Venus Optics brings its Laowa 9mm T2.9, 12mm T2.9 and 15mm T2.1 cine primes to Canon RF mount

28 Sep

Venus Optics has announced it’s now adding a Canon RF lens mount option for three of its ultra-wide cinema primes: the 9mm T2.9 ‘Zero-D’ lens, 12mm T2.9 ‘Zero-D’ lens and 15mm T2.1 ‘Zero-D.’

The 12mm T2.9 ‘Zero-D’ lens was released back in January of this year, while the 9mm T2.9 and 15mm T2.1 ‘Zero-D’ lenses were announced back in June of this year. At the time, the lenses were only available for Sony E, Canon EF and PL mount, but owners of Canon’s EOS R series mirrorless cameras can now get native versions of the lenses, negating the need to use the EF version with the EF-RF adapter.

Canon announces the EOS C70, a Cinema EOS camera in a mirrorless body

24 Sep

Canon has announced the EOS C70, a digital cinema camera with a body that resembles a mirrorless stills camera. Notably, the C70 uses Canon’s RF lens mount, making it the first Cinema EOS camera to adopt the company’s newest lens system.

The EOS C70 features a Super35 sensor using Canon’s next-generation Dual Gain Output (DGO) technology. The DGO sensor reads each pixel at two different gain levels, with one prioritizing saturation and highlight protection and the other suppressing noise in the shadows.

When combined, Canon claims the camera can deliver 16+ stops of dynamic range at up to DCI 4K/60p or 2K/120p (using a Super16 crop). It can also capture 4K/120p and 2K/180p without extended dynamic range. Recording choices include both All-I and intra-frame options using Canon’s XF-AVC or MP4 (H.265) codecs.

Other features that should appeal to video shooters include dual-pixel autofocus, a motorized 10-stop ND filter, C-Log2/C-Log3, PQ and HLG gamma for HDR, two mini XLR mic inputs, thirteen customizable buttons, and custom in-camera LUTs.

An air intake system provides cooling, allowing the camera to record for extended periods. The cooling system is outside the sealed part of the camera to prevent dust or moisture from reaching the electronics.

The camera features a 3.5-inch 2.76M-dot rear LCD but not an electronic viewfinder. Presumably, Canon expects many Cinema EOS users to put the camera in a rig with their preferred EVF or external monitor.

Alongside the camera, Canon also announced the Canon Mount Adapter EF-EOS R 0.71x, which allows users to attach EF-mount lenses to the C70. Unlike Canon’s existing EF to EOS R adapters, the EF-EOS R 0.71x is an optical adapter that works like a speed booster, making it possible to use EF lenses on the smaller Super35 sensor at their intended focal lengths while increasing lens speed by one stop.

The EOS C70 will be available in November for $ 5499. The EF-EOS R 0.71x adapter will follow in December for $ 599.

READY FOR ACTION: THE CANON EOS C70 4K DIGITAL CINEMA CAMERA PACKS CINEMA EOS IMAGING FEATURES INTO STILL CAMERA ERGONOMICS

The First Cinema EOS Camera with an RF Mount, this New Compact and Lightweight Model Features a Super 35mm Dual Gain Output (DGO) Sensor, DIGIC DV7 Image Processor, ?and 16+ Stops of Total Dynamic Range

MELVILLE, N.Y., September 24, 2020 – Canon U.S.A., Inc., a leader in digital imaging solutions, is excited to announce the company’s first-ever RF mount Cinema EOS camera, the EOS C70 4K Digital Cinema Camera. When the Canon RF mount was first introduced, imaging professionals began to dream about the possibilities that this revolutionary mount system might provide them. One request that Canon consistently heard was to put an RF mount on a Cinema EOS camera so that future lens performance could capitalize on the short flange depth. Just two short years later, those wishes have come true with the new C70 camera.

The unique design of the EOS C70 camera puts a significant emphasis on operational convenience for the end-user. The small form-factor, weighing only 2.6lbs., allows the camera to be easily handheld and dramatically enhances a videographer’s mobility, providing a seamless bridge between the EOS and Cinema EOS families for cinematic applications. Cleverly designed, the camera features a slim, motorized ND filter unit – having a mere 6mm depth – that is built into the short flange back of the RF mount. The motorized 10-stop ND filter provides users with the flexibility to control exposure while keeping the desired depth-of-field and capturing images that feature the desired level of bokeh. Thirteen customizable buttons allow users to select from more than 80 functions to be assigned based on individual preferences.

“The Canon EOS C70 camera is truly a special tool that will undoubtedly satisfy and delight a variety of users on the search for a high-powered piece of video equipment,” said Tatsuro “Tony” Kano, Executive Vice President and General Manager of Canon U.S.A.’s Imaging Technologies & Communications Group. “In today’s fast-moving, ever-changing world of filmmaking and content creation, versatility is key, and the EOS C70 will provide a familiar form and feature set to our entire spectrum of imaging customers. We are eager to see how creatives use this tool and the projects that come from it.”

The camera features Canon’s innovative and next-generation Super 35mm DGO Sensor that further extends the high dynamic range and lowers noise levels by reading out each photodiode with two different gains. One gain prioritizes saturation – protecting detail in highlight areas – while the other suppresses noise in the shadows. The result is an image with up to 16-plus stops of total dynamic range, clean, rich shadows, and vibrant highlights in up to 4K/ 60p or 2K/120p in Super16mm Crop mode. The EOS C70 camera also features Canon’s recently developed DIGIC DV7 image processor that collects the extensive information captured from the DGO sensor and processes it into exceptional HDR imagery while offering choices between Canon Log 2 and 3, in addition to PQ and HLG gamma functionality. The C70 camera can also record 4K DCI or UHD up to 120fps and 2K DCI or HD up to 180 fps – with an important flexibility in the choice of codecs.

The camera supports XF-AVC format (in variable bit-rate) – both Intra and Long GOP with MXF file format. The intra-frame format compresses the data after analyzing each frame separately, while Long GOP format compresses data at a higher rate, creating an even smaller file size. A secondary choice is Long GOP 10-bit 4:2:2/4:2:0 MP4/HEVC (a next-generation HDR video recording compression standard) with an MP4 file format – a first in the Cinema EOS line.

The camera’s independent air intake system is separated from the electrical systems to protect the sensor from water, sand, and dust. In addition, the camera also features two air outlet vents that allow uninterrupted recording for extended periods of time.

Additional features of the Canon EOS C70 4K Digital Cinema Camera include:

  • New Direct Touch Menu System
  • Coordinated Electronic Image Stabilization
  • Two built-in Mini XLR inputs
  • Time-code input/output terminal
  • Custom picture processing via import of 3D LUTs and recording to Look Files
  • Dual-SD card slots
  • Built-in stereo mic
  • Support for optional Canon RC-V100 remote control

Canon Mount Adapter EF-EOS R 0.71x

The Canon Mount Adapter EF-EOS R 0.71x is a new optical adapter that allows users to tap into Canon’s extensive collection of superb full-frame EF lenses when operating the EOS C70 camera. The adapter implements two critically important functions – preserving the similar FF wide angle image onto the 4K Super 35mm image sensor while simultaneously elevating the lens camera sensitivity by one stop. The mount adapter preserves full electronic communication between the lens and camera, enabling optical lens corrections and transfer of lens metadata between the EOS C70 camera and select Canon EF lenses*. ?

Price & Availability?

The Canon EOS C70 4K Digital Cinema Camera is scheduled to be available in November 2020 for an estimated retail price of $ 5499.00. The Canon Mount Adapter EF-EOS R 0.71x is scheduled to be available in December 2020 for an estimated retail price of $ 599.99**. For more information please visit cinemaeos.usa.canon.com.?

* Compatible EF lenses are EF16-35mm F2.8L III USM, EF24-70mm F2.8L II USM and EF24-105mm F4L IS II USM. As of September 24, 2020. Firmware update provided free of charge, compatibility will be added for additional EF lenses in the future. Even if you do not update the firmware, you can use the EF lens, but it is recommended to use the firmware update in order to effectively use the function linked with the camera.

Canon is crowdfunding its monocular-style PowerShot Zoom concept camera in Japan

15 Sep

Last year, at CP+ 2019, Canon showed off a number of concept cameras with new and unusual designs. While some of those concepts are still just that, at least one more is well on its way into the consumer market — in Japan, at least.

The Canon PowerShot Zoom is a monocular-style point-and-shoot that’s being crowdfunded on Makuake, not unlike the approach Canon took with its Ivy Rec camera. Inside the almost cartoon-looking design is a 12.1-megapixel 1/3” CMOS sensor that works alongside a DIGIC 8 processor to capture stills and record Full HD video at 1080p.

In front of the sensor is a zoom lens that can toggle between 100mm and 400mm (full-frame equivalent) focal lengths. You can also double that to an 800mm (full-frame equivalent) focal length when combined with the camera’s digital zoom.1 The device features built-in image stabilization, Canon’s Face AF technology, a USB-C port for charging and a microSDXC card slot.

The camera features three buttons on the top: power, menu and zoom, as well as three on the bottom: a dial, a capture button for stills and a capture button for video. Photos and video can be transferred via the microSD card or wirelessly when paired with Canon’s accompanying smartphone app.

The PowerShot Zoom is currently being crowdfunded in Japan through Majuake. The campaign has already raised over $ 280,000, far surpassing its initial goal. Japanese backers are able to secure the first units for around $ 300.

There’s no mention of whether or not the PowerShot Zoom will become available outside the Japanese market at this time.


Disclaimer: Remember to do your research with any crowdfunding project. DPReview does its best to share only the projects that look legitimate and come from reliable creators, but as with any crowdfunded campaign, there’s always the risk of the product or service never coming to fruition.

1Canon had previously said it hoped to have intermediary focal lengths during zoom, but it appears that feature isn’t available at this time.

Canon releases major firmware update for its EOS R6, minor update for the EOS R5

11 Sep

Canon has released a firmware update (version 1.1.1) for its EOS R6 mirrorless camera that brings with it a number of improvements previously given to the EOS R5 via a version 1.1 firmware update late last month. Additionally, Canon has released a small bug-fix update for the EOS R5 as well.

Starting with more substantial improvements to the EOS R6, firmware version 1.1.1 claims to improve the total recording time on the EOS R6. No specific performance increase metrics are given beyond saying the limit has been ‘improved,’ but we plan to put it to the test to find out.

Other major fixes in the firmware include improved in-lens image stabilization when shooting ‘certain’ RF lenses during movie recording and improved connectivity during FTP transmission. Smaller fixes include improved support with the RF 100–500mm F4.5–7.1 L IS USM lens and a number of menu fixes. You can download firmware version 1.1.1 for the Canon EOS R6 below:

Firmware version 1.1.1 for the EOS R6

Firmware version 1.1.1 for the EOS R5 is less substantial than the EOS R6 update, but is still worth mentioning and updating to if you’re an EOS R5 owner. The only changes include the same lens compatibility improvements for the RF 100–500mm F4.5–7.1 L IS USM lens as found in the EOS R6 firmware update. Specifically, Canon notes the following changes:

  1. When the RF100–500mm F4.5–7.1 L IS USM lens is attached, an image stabilization effect of approximately six stops* is achieved through collaborative control with the in-lens image stabilization. *Focal length 500mm, Based on CIPA (Camera & Imaging Products Association) standards.
  2. Fixes a phenomenon in which the IS capabilities may be degraded when performing continuous shooting in cases where the RF100–500mm F4.5–7.1 L IS USM lens is attached to the EOS R5 running firmware version 1.1.0.

You can download firmware version 1.1.1 for the Canon EOS R5 below:

Part II: Lensrentals investigates the Canon EOS R5’s heat emission

10 Sep
Image credits: Photos published with kind permission from Lensrentals.

Following up on the Canon EOS R5 teardown, Lensrentals has published a follow-up piece investigating the heat emission of the Canon R5.

Before digging into the investigation, it’s worth covering some basics. Electronics in cameras produce heat while operating and to ensure full, uninterrupted operation, heat must be controlled. You can remove heat from critical areas in a camera ‘by conduction (flowing through nearby materials), convection (circulating through gas or fluids), and radiation (which mostly occurs at high temperatures).’ Based on his experience tearing down the Canon EOS R5 with Aaron Closz, Roger Cicala knows that the R5 is tightly sealed, which is great for keeping water out of a camera but not ideal for releasing heat from inside the camera. This means that convection, circulating heat through air, ‘doesn’t play much of a role.’

Cicala avoids discussions about chip operating temperatures, the thermal flow of different substances in a camera, firmware cycles and the like, as they are not his area of expertise. Instead, he focuses on the basic issue of how heat generated by the operation of a fully assembled Canon R5 camera exits the camera. At some point, especially when doing an intensive task such as recording 8K video footage, the camera will overheat and the heat either needs a suitable exit path or the camera needs to shut down. You can learn more about different usage cases and how long the R5 can operate being shutting down by checking out our Canon R5/R6 overheating test.

Lensrentals’s initial testing methodology involves using a Canon R5 camera running version 1.0 firmware recording 8K video to a CFx card. The camera was then run until it reached a temperature cut off while the team used industrial thermometers to monitor the heat of the camera and see where heat was exiting the R5.

With a lens attached, with all covers closed and with the LCD folded against the camera body, the R5 ran for 18 minutes on a table before getting a temperature warning. Lensrentals found that the hottest part of the camera was the back behind the LCD with a temperature of 43°C / 109°F. The thumb rest was slightly cooler at 40°C / 104°F and the bottom plate around the tripod socket 38°C / 100°F. The test was run again with the LCD moved to the open position and the camera was a few degrees cooler but was unable to record for a longer duration.

Next, Lensrentals ditched the thermometers in favor of a FLIR IR camera. Cicala has long suspected that the lightweight material used for camera chassis and shells aren’t good conductors of heat. With a removed R5 shell as the test subject, it turns out Cicala’s assumptions were right. He says, ‘The shell material doesn’t spread heat especially well…Obviously, it does pass heat out of the camera to some degree, but it sure doesn’t act as a heat sink or anything.’ Cicala continues, ‘Even exposed to air, it was over 10 minutes before [the shell] cooled down to room temperature. This kind of poses the question that if heat isn’t getting out of the shell very well, then how does the heat get out?’

With the FLIR IR camera, the team redid the original recording test, and lo and behold, the warm spot found by the thermometer is immediately evident in the FLIR IR image. Cicala overlaid an image from the R5 teardown and no surprise, the hot spot is located above the camera’s processor and SDRAM cards.

Cicala is careful to point out, ‘This is NOT an image with the back off. It’s an image of inside of the camera overlaid on the heat image to correlate location.’ Image credit: Lensrentals, 2020

The front of the camera showed a bit of warmth and the top of the camera remained quite cool. Cicala wondered if the heat from inside the camera might rise through the air inside and reach the top plate, but as the teardown showed, there’s very little empty space inside the R5. The viewfinder also acts to block some heat transfer.

When taking apart the Canon R5, Lensrentals noted that there’s a heat sink connected to the metal tripod plate. The FLIR IR image shows that the bottom of the camera does get quite warm. In the image below, captured at thermal cut-off, you can see the metal screws that go into the tripod plate heating up. The tripod socket itself, for some reason, remained quite cool.

As the camera heats up to the point where it needs to shut off, heat is showing in the FLIR IR images in numerous places. The metal lugs for the camera strap get very hot, the front of the camera is now quite hot, especially around the lens mount area, and the area near the card slot door also heats up considerably. The hottest spot of the camera during testing proved to be the CFx slot itself, at nearly 48° C.

After upgrading the R5 to firmware version 1.1, recording times before cut-off increased, but so did the operating temperatures of the camera. Of interest here is that the I/O ports connected to the main PCB itself got ‘quite hot,’ but the ports attached to the sub-board didn’t seem to heat up much at all. The image sensor itself also quite hot, nearly 50° C. An anonymous friend of Lensrentals read the internal temperature from a raw image captured during the temperature testing. That image showed an internal temperature of 61° C, which is hotter than the CFx card slot, meaning that somewhere inside the camera is hotter than the hottest temperature Lensrentals measured during testing.

After testing, Lensrentals has a few interesting conclusions. Heat does not leave the R5 very well, and it seems to exit primarily via metal parts of the camera body. Further, the camera is hotter inside than at its hottest exit points. Cicala writes, ‘If [the R5] doesn’t get heat out very well, it certainly can’t be expected to cool down quickly after it turns off from overheating. Cooling the outside of the camera should help a bit, but it’s not going to be very efficient.’

There are some steps you can take to possibly help the camera stay cooler, such as leaving the LCD opened away from the back of the camera, opening the HDMI port cover (remember, this port is attached directly to the main board), and saving to SD cards when possible, which is of course not possible when recording 8K video. However, Cicala doubts that these steps will make a significant difference. Perhaps more effective steps would be to remove the lens, open the shutter and open the memory card doors will help. These aren’t steps you necessarily should have to take in order to use a camera the way you want to.

More enterprising individuals may opt to try minor modifications. Cicala says, ‘Some people intend to do more aggressive things to extend recording time. It would certainly be possible, with some minor modifications, to connect the metal heat sink plates to the outside world. You might do so by just exposing the bottom tripod plate and attaching a sink to that. Of course, you lose weather sealing, but it would be simple to try.’

Maybe removing the weather sealing and opening parts of the camera would help, but to really fix the overheating issue, someone will have to figure out a way to improve heat transfer from inside the camera, as there appears to be a thermal bottleneck deep within the R5. Cicala provides a humorous image as to what a ‘redneck 8K video camera’ might look like after modifications.

For many more images and to read Cicala’s full speculation about whether the Canon R5 can be ‘fixed’ and whether it even needs fixing in Canon’s eyes, read the full article on the Lensrentals blog.

Adobe Camera Raw vs. Canon Digital Photo Professional: Which should you use and why?

10 Sep

If you’re like many photographers, the first thing you do upon taking a brand-new camera out of its package is to set aside the included software download info (or, with older cameras, the CD or DVD), opting instead for a third-party option like Adobe’s Camera Raw or Lightroom. But is that a smart move in our newly-normal, more cost-conscious world, or could you get by just as well with your camera’s bundled software?

Canon Digital Photo Professional version 4.12’s user interface.

That’s a question we’ve wanted to answer for a while now, and one which I’ll discuss in a new series of articles comparing the user interfaces, performance and image quality of the manufacturer’s apps with those of their much-vaunted Adobe rival. In the interests of keeping things to a readable length, I’m limiting myself only to image editing, and won’t address features like image management, tethering or printing.

The ground rules

In this article, I’m comparing Adobe Camera Raw 12.4 alongside Adobe Bridge 10.1.1 versus Canon Digital Photo Professional 4.12.60.0, all of which are their current versions. My computer is a 2018-vintage Dell XPS 15 9570 laptop running Windows 10 version 1909.

To ensure neither Adobe nor Canon had any advantage out of the gate, I’ve aimed to reproduce, as closely as possible, the look of already-processed images from our galleries, without any prior knowledge as to the recipes behind them. I’ve chosen images from the EOS R for use in this comparison, for reasons we’ll come to in a moment.

Adobe Camera Raw version 12.4’s user interface.

To avoid getting too far into the weeds, sharpness and noise reduction were left at their defaults, while lens corrections were enabled for both apps with the exception of distortion correction, so as to make for easier comparison to our reference shots from the gallery.

Images processed in ACR were saved at JPEG quality 11, just as used in our galleries. For DPP, I saved at JPEG quality 8, producing near-identical file sizes.

The main differences

Of course, the most immediately obvious differences between ACR and DPP are their camera support and pricetag. You already paid for DPP when you bought your Canon DSLR, so it’s effectively free. While it only supports Raws shot by the company’s own cameras, you can expect full Raw support for almost every Canon camera to be available more or less immediately upon release.

Click or tap for the full-sized ACR version; here for DPP version

By contrast, ACR comes with a recurring subscription fee. While it supports a vast range of cameras from many manufacturers – even a couple of older Canon models that DPP no longer recognizes – that support can take some time to arrive after the release of new cameras. It’s also sometimes more limited than that in first-party software. For example, Adobe doesn’t yet offer ‘camera matching’ profiles for any Canon camera released since September 2018. (That’s why I selected the EOS R for my comparisons here.)

Camera Raw’s UI is more modern

Overall, DPP’s user interface feels more dated than that of ACR, and occasionally more obtuse and frustrating. Both applications support modern features like 4K displays, touch-screens and pen control, although I did notice a few minor glitches in DPP’s 4K support.

But where Adobe’s controls are grouped together in clearly-named, collapsible sections within a single panel, DPP’s span no less than nine different tabs, each identified only by a small icon. And many of DPP’s sliders for contrast, tone, saturation etc. jump in large steps, unlike ACR’s which move smoothly and precisely when dragged. For finer-grained adjustments, you must either type in values directly or click tiny arrow buttons.

And the locations of DPP’s controls aren’t always logical, nor are their names always intuitive. For example, even if you’ve tweaked multiple images at once, the large Save button at the top of the screen won’t process them together. Instead, you have to find a Batch Process command hidden within the File menu.

ACR is also much faster to use

But the biggest difference between ACR and DPP, operationally speaking, is in their performance. Compared to its Adobe rival, Canon’s app feels glacially slow to use.

When you move sliders in ACR, the preview image updates in real time to show your change before you’ve even released the mouse button, even when using a 4K display. But DPP’s previews frequently take anywhere from a couple of seconds to 10 seconds or more to update after releasing the mouse button. Worse still, the preview often updates in multiple passes, initially showing results that, misleadingly, differ significantly from the final pass.

Things are no better when it comes to final output performance, either. Processing all six comparison images for this article in ACR took just 16 seconds, start to finish. DPP required longer than that to process a single image, making it 6-7 times slower than its Adobe rival. Processing all six images in DPP took a full 108 seconds – and that’s even with it configured to take advantage of my graphics processor, which it wasn’t by default.

The settings chosen for a given image do impact on performance somewhat, but they don’t come close to explaining DPP’s modest performance. Even with all six images reverted to out-of-camera settings and with all lens corrections disabled, DPP still needed 81 seconds to complete its work.

ACR makes lighter work of shadow / highlight control

Although most of their basic controls are broadly similar, ACR offers a few extra tools that DPP lacks. Both applications give you a one-click auto control to get basic settings in the ballpark, plus slider control over brightness, contrast, shadows, highlights, saturation and tone. But ACR adds sliders for vibrance, texture, clarity, dehazing and blacks/whites.

I particularly missed these last two, and while DPP’s dynamic range control helps make up for their absence, I found it less intuitive to use. Even with it, I had to resort to finely tweaking curves to try to hold onto the brightest highlights and deepest shadows, using the keyboard arrows to more finely position the points than I could with a mouse or touchpad.

Both applications are capable of great results with a little effort

ACR’s one-click auto control tended to hold onto highlights and open up shadows much better than did DPP. But in return, Canon’s auto control yielded more realistic colors, although it sometimes felt too muted in foliage. Adobe’s results, meanwhile, tended decidedly towards the contrasty and garish, especially in foliage and skin tones.

At default settings, DPP tended to control noise a little better than did ACR, although that advantage came at the expense of the finest image detail. In fact, even with its noise reduction sliders zeroed out completely, DPP showed similarly low levels of noise to ACR with both luminance / color noise reduction sliders set at around level 25-30.

But you really have to pixel-peep to notice these subtle differences. The effects of lens correction were much more noticeable, and both applications did a great job of automatically taming lens defects like chromatic aberration and vignetting.

Overall, I felt that neither ACR or DPP had a huge edge over the other in terms of basic editing. However, I found ACR quite a bit easier to work with, and spent several times as long working to get similarly-pleasing results from DPP.

Final thoughts

Although it’s capable of images just as good as those from ACR with a little effort, I personally found DPP’s interface and performance issues quite off-putting. If you’re on a shoestring budget, it could make sense as an alternative to paying the Adobe tax every month, freeing up cash for other gear at the expense of some convenience. But if you can afford it, I recommend spending the extra on Camera Raw for a much faster, more intuitive editing experience.

Lensrentals tears down the Canon EOS R5 and finds interesting sealing and thermal flow

09 Sep

Since Canon announced the 8K-capable EOS R5 mirrorless camera, there has been heated discourse online about the thermal flow inside the camera and its propensity to overheat. Curious photographers have been wondering what the inside of the EOS R5 looks like and what sort of design features Canon has implemented into its latest high-resolution full frame camera. Wonder no more as Roger Cicala and Aaron Closz at Lensrentals have disassembled a Canon R5 to see what’s going on inside.

In terms of thermal design, when tearing down the R5, the duo found multiple heat sinks and thermal pads. For a photo camera, there is a lot of heat sink inside the EOS R5. However, compared to a video camera, the R5 features ‘not even a fraction of what’ is seen in a video camera.

Cicala speculates that it’s possible the camera has been designed to allow heat to exit through the top panel of the camera, as the connection of the top panel to the main body does not feature the same level of sealing found in the connections between the body and the bottom and side plates.

Speaking of sealing, after having removed the camera’s grip, battery door, bottom plate and side plates, Cicala and Closz found an impressive level of sealing throughout the camera. The battery door has weather resistant gaskets around the edge and the bottom of the battery door compartment itself is a soft gasket material.

Along the bottom plate, Canon placed a ‘soft rubber gasket along the entire mating edge of the pieces.’ This provides a ‘greater seal area’ than what is usually seen in disassembled cameras at Lensrentals headquarters. The same sealing gaskets found here are also present where other body parts are sealed together, such as along the sides of the camera.

Of the weather sealing in the EOS R5, Cicala writes, ‘When we took these pieces apart, you feel the suction when they disengage. That’s not something we’ve seen in other cameras. The thing about weather sealing is it only takes one weak place to leak, but this sealing seems to be a step up from anything we’ve seen before.’ This is certainly a promising find for prospective R5 owners.

While there are gaskets around the I/O ports on the R5, Cicala notes that the HDMI and digital out ports are part of the main printed circuit board (PCB). This means that users should be careful to not damage these ports, as it will result in an expensive repair. On the other hand, the tripod plate and tripod mount itself are both replaceable parts and not soldered anywhere. This is great news for the team at Lensrentals, as they regularly must take apart cameras to make repairs like this before sending them out to new customers.

Moving to the back of the camera, the R5 has more dials than the EOS R but maintains an identical wiring arrangement. There’s a new flex design on the LCD side and you can even see a mark made by a Canon tech in the image below.

On the back of the circuit boards, there is a notable difference between the EOS R5 and the EOS R. The new camera has ‘immensely more intense and dense circuitry.’ In the image below, the green sub-board ‘appears to be about DC power conversion.’ On the left black board, the large white chip is a Wi-Fi chip.

Located beneath the green sub-board is either an aluminum heat sink or an electronic shield. Cicala notes that ‘electronic shields tend to be quite thin, but this is a manly piece of aluminum, 0.98mm thick. I speculate it’s more about heat than electronics. Notice I said ‘speculate.”

When removing the main PCB, Cicala and Closz found a large aluminum heat sink on the underside of the board. There is a layer of insulating tape over the sensor as well. There is also a thermal pad located underneath the CPU, which Cicala speculates means that Canon is directing heat from the four SDRAM chips located around the CPU to one heat sink and the heat from the CPU itself to a different area.

After removing the circuitry, the Lensrentals team was able to inspect the image stabilization system and image sensor arrangement. The sensor assembly is held in place by three screws. To ensure that the image sensor stays perfectly parallel to the lens mount, Canon uses shims to make tiny adjustments. The EOS R used spring tension screws instead. Cicala assumes that ‘the vibration of an IBIS unit could loosen them over time’ and notes that ‘every IBIS camera we’ve opened uses shims.’

Once the circuitry and image sensor/IBIS unit has been removed from the R5’s body, there’s not much left besides the shutter assembly. Lensrentals don’t take apart shutter assemblies as they are incredibly labor-intensive to rebuild and if anything is not lined up perfectly, the shutter timing will be off and only factory software can be used for recalibration.

The sensor is mounted directly to the IBIS plate. Some cameras use screws and plastic tabs to support the sensor, which Lensrentals has seen result in fractures. ‘On all the edges of the Canon unit, the sensor is mounted directly to the IBIS plate; no tabs. That doesn’t mean it can’t break, of course, or glue comes loose. But this seems sturdier to me,’ says Cicala.

Summing up the findings, Cicala writes that the R5 is ‘pretty thoroughly filled up, there are lots of parts and not much air.’ The new weather sealing method found in the lower two-thirds of the camera ‘seems to give a really, really tight seal.’ The IBIS unit ‘is very compact but well-engineered.’

With respect to thermal flow, Cicala believes there are a pair of separate heat sinks. One of them is located under the voltage board and the other between the main PCB and sensor assembly. Both heat sinks include thermal pads to direct heat. There may also be a heat sink in the tripod plate, although it’s unclear. Cicala says, ‘In a small photo camera, there’s not a lot of ventilation/convection current to let the heat out. This camera is better sealed than most; I doubt there’s very much ventilation at all. Somebody should look into that.’

Jakumei Optics announces the $735 Dulens APO 85mm F2 for Canon EF, Nikon F mounts

08 Sep

Chinese lens manufacturer Jakumei Optics has announced (translated) the release of the Dulens APO 85mm F2 manual lens for Canon EF- and Nikon F-mount camera systems.

According to the manufacturer, the lens’ apochromatic (APO) design is inspired by ‘Sonnar-style’ lenses, the first of which was created by Dr. Ludwig Bertele in 1929.

The lens is constructed of seven elements in six groups, including two extra-low dispersion elements and one high-refractive index lens. Other features include an aperture range of F2-F16, a nine-blade aperture diaphragm, a 90cm (3ft) minimum focusing distance and a 55mm front filter thread.

The lens is available in black, grey and silver, and is available to purchase on the Shoten Kobo website (translated) for approximately $ 735 (76,950 JPY).
