Tamron announces 70-210mm F4 Di VC USD for full-frame DSLRs

22 Feb

Tamron is introducing a stabilized 70-210mm F4 tele-zoom for full-frame Canon and Nikon DSLRs. The lens uses an internal zoom mechanism so that the overall length never changes as it’s operated and a ring-type ultrasonic motor. It also offers moisture-resistance, up to 5 stops of stabilization and a close focusing distance of 0.95m/37.4in. The 70-210mm F4 includes 20 optical elements in 14 groups, including 3 low-dispersion elements to reduce chromatic aberration.

The 70-210mm F4 is compatible with Tamron’s 1.4x and 2.0x teleconverters, as well as the company’s Tap-in Console for easy firmware updates. Arriving this April in Canon and Nikon mounts, the 70-210mm F4 will sell for $ 800 – quite a bit cheaper than the offerings from those two manufacturers.

New F/4 telephoto zoom lens featuring superb optical performance and a lightweight and compact body for easy portability

70-210mm F/4 Di VC USD (Model A034)

February 22,2018, Commack, New York— Tamron announces the launch of the 70-210mm F/4 Di VC USD (Model A034), a compact telephoto zoom lens for full-frame DSLR cameras. Model A034 provides superb optical performance throughout the entire zoom range and features a maximum magnification ratio of 1:3.1, the highest in its class.* The design includes an internal zoom mechanism that provides solid mechanical construction and stable, reliable operation. Model A034 also employs a Dual MPU (Micro-Processing Unit) design, which enables high-speed and high-accuracy AF performance as well as powerful VC (Vibration Compensation) image stabilization for flexible and versatile use in various situations. For dependable outdoor use, the new telephoto zoom is equipped with Fluorine Coating and Moisture-Resistant Construction. The lens will be available in Canon and Nikon mounts in April at $ 799.00.

PRODUCT HIGHLIGHTS

1. High-performance telephoto zoom lens with a constant maximum aperture of F/4
Leveraging Tamron’s years of knowhow developing telephoto zoom lenses, Model A034 achieves superb optical performance with high contrast and resolution. The optical construction (20 elements in 14 groups) uses three LD (Low Dispersion) lens elements to effectively compensate for axial and transverse chromatic aberrations, thereby ensuring crisp and crystal-clear image quality across the entire frame. Furthermore, Model A034 features a constant maximum aperture of F/4 throughout the entire zoom range, thus providing superior control over depth-of-field and excellent bokeh. Compared to large aperture telephoto zoom lenses, the new A034 is lighter with a weight of just 30.3 oz. and is more compact with a total length of only 6.8 in. for excellent portability. The lighter weight and smaller size make this new lens easier to carry and instantly spring into action.

2. Class-leading magnification ratio and MOD (Minimum Object Distance)
Model A034 boasts the highest-in-class maximum magnification ratio of 1:3.1 and the shortest-in-class* MOD of 37.4 in. The shorter working distance enables photographers to capture close-up images of small objects like flowers while using a telephoto zoom.

*Among 70-200mm F/4 class interchangeable lenses for full-frame DSLR cameras (as of January 2018: Tamron)

3. Highly reliable internal zoom mechanism
Thanks to an internal zoom mechanism, the physical length of the A034 does not change during zooming, thereby minimizing changes in the center of gravity and providing more stable use and operation. In addition, it’s not necessary for the photographer to move backwards even when shooting space is limited, for instance, when photographing through a wire mesh fence at a zoo. So-called “zoom creep” is impossible because the overall length never extends. Furthermore, the design provides a very robust and sturdy feeling, and the non-rotating front element makes the use of polarizing filters much easier.

4. High-speed Dual MPU (Micro-Processing Unit) control system delivers responsive autofocus performance plus outstanding VC (Vibration Compensation) image stabilization
The Dual MPU system includes two high-performance MPUs (micro-processor units) dedicated to VC processing and lens system control. Both MPUs have a DSP (Digital Signal Processing) block that provides high-speed digital signal processing, improving the computing power of the entire system. This new control system achieves high-speed and precise AF performance as well as assured VC effects.

Excellent autofocus performance
Model A034’s AF drive system uses a USD (Ultrasonic Silent Drive) ring-type ultrasonic motor for outstanding responsiveness and to ensure fast, precise focusing. Plus, the new zoom is equipped with a Full-time Manual Focus override mechanism that enables a photographer shooting with AF to instantly make fine manual focusing adjustments without switching the AF-MF mode switch.

Outstanding vibration compensation effects
The new A034 is equipped with Tamron’s proprietary VC system and achieves the CIPA image stabilization performance level of 4 stops.* Even in low light or with slow shutter speeds, photographers can enjoy shake-free handheld shooting with ease and comfort.

*CIPA Standard Compliant. For Canon: EOS-5D MKIII is used; for Nikon: D810 is used.

5. Fluorine Coating
The surface of the front element is coated with a protective fluorine compound that has excellent water-and oil-repellant qualities. The front surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture or oily fingerprints, allowing for much easier maintenance. The coating also provides an enhanced level of durability, and will sustain its effectiveness for years.

6. Moisture-Resistant Construction
Seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops to provide Moisture-Resistant Construction. This feature affords an additional layer of protection when shooting outdoors under adverse weather conditions.

7. Compatible with Tamron teleconverter
The new lens is also compatible with the TELECONVERTER 1.4x (Model TC-X14) and TELECONVERTER 2.0x (Model TC-X20), which increase the focal length of the lens to 1.4 times and 2 times the original, respectively. Both teleconverters are carefully designed and constructed to provide outstanding high image quality.

Note: For more detailed information about teleconverters, please refer to the Tamron website.

8. Compatible with TAMRON TAP-in ConsoleTM, an optional accessory
The new A034 is compatible with the optional TAMRON TAP-in Console, an optional accessory product that provides a USB connection to a personal computer, enabling users to easily update a lens’s firmware as well as customize features including fine adjustments to the AF and VC.

9. Optional tripod mount compatible with Arca-Swiss style quick release plates
For rapid attachment to a tripod, an Arca-Swiss style tripod mount is available as an optional accessory. Featuring a hinge-type ring section, connection is easy even when the lens is mounted on a camera. To maximize the advantages of the small and lightweight F/4 zoom lens, the tripod mount is made of lightweight, sturdy magnesium alloy.

10. Electromagnetic diaphragm system now used also for Nikon-mount lenses
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses.* More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a built-in motor through electronic pulse signals.

*Available only with cameras compatible with the electromagnetic diaphragm (D5, D4s, D4, D3X, Df, D850, D810, D810A ,D800, D800E, D750, D600, D610, D300S, D500, D7500, D7200, D7100, D7000, D5600, D5500, D5300, D5200, D5100, D5000, D3400, D3300, D3200, D3100). (As of January 2018; Tamron)

2018 Japan BCN camera rankings: Canon dominates DSLRs, tops Sony in mirrorless

18 Jan
Photo by Mario Calvo

The 2018 Japan BCN camera rankings are in, and they show that (surprise, surprise) Canon is still veritably dominating the DSLR space with 61.1% marketshare, only a slight drop from its previous 63.3% share. More impressive is Canon’s performance in the mirrorless category where Canon took the number 2 position, hitting 21.3% versus Sony’s 20.2%. Olympus beat both to take top slot in mirrorless at 27.7%, though, a small increase over its previous 26.8% marketshare.

According to BCN, Canon also topped the “digital camera with integrated lens” category, holding 27.9% of marketshare over Nikon’s 25.5% and Casio’s 17.2%. The BCN rankings also look at action cameras, which saw GoPro take top slot with 67.2% marketshare (not that this has helped the company’s outlook lately…), as well as digital video cameras, which has Panasonic on top with a 42% marketshare.

When looking at previous figures, the rankings show Nikon growing in DSLR sales while Canon and Ricoh both saw decreases. Olympus, Canon, and Sony all experienced growth in the mirrorless category, while Canon and Nikon both experienced growth in the integrated lens digital camera market.

Notably, Canon continues to show strong growth in Japan’s mirrorless market despite Sony’s recovery from the disruption caused by the 2016 Kumamoto earthquake.

That earthquake had impacted Sony’s nearby image sensors facility, which supplied sensors for both Nikon and Olympus, among others. In its early 2017 fiscal quarterly results, Olympus had noted that the 2016 Kumamoto earthquake had a negative impact on its Imaging Business sales. Likewise, Nikon had revealed its own Imaging Products Business impact during the same time, resulting in downwardly revised forecasts.

However, despite Sony’s facility restoring operations in the many months since the earthquake, Canon is still outpacing Sony in the mirrorless segment.

Though Nikon saw DSLR marketshare growth in 2017, whereas Canon saw a slight decrease, the latter company still trounces its closest competitor at 61.1% versus Nikon’s 34.4%. Whether Canon’s biggest competitors will see any significant 2018 gains on the company in their respective categories is anyone’s guess.

Smartphones dominated Flickr’s 2017 uploads, but DSLRs are on the rise

13 Dec
Photo by Max Delsid

The iPhone has dominated Flickr’s annual ‘top devices’ list, representing 54% of the site’s top 100 devices in 2017, as well as the majority of the site’s 10 top devices list. These figures were published as part of Flickr’s end-of-year analysis, in which the platform reveals what cameras are most popular among its users, as well as highlighting the site’s top photos of the year.

Flickr’s 2017 Year in Review report shows that smartphones were once again the device of choice among the site’s users, increasing from 48% in 2016 to a full 50% of uploads in 2017.

But it’s not all smartphones this and smartphones that. In fact, DSLRs were used to take 33% of the images uploaded to Flickr this year compared to just 25% in 2016. And in an utterly predictable turn of events, the use of point-and-shoot cameras dropped from 2016’s 21% to a paltry 12% this year.

Mirrorless cameras were the only ones to hold steady, boasting just 4% of uploads in both 2016 and 2017.

Looking at brands specifically, Apple dominates Flickr’s 2017 annual review, with its iPhone representing 54% of the top 100 devices of the year. Flickr says that 9 of the top 10 devices were iPhone models; only the Canon 5D Mark III tarnished that record, coming in at #9. Canon, overall, was the second biggest brand on Flickr this year, accounting for 23% of the top 100 devices. Nikon came in third at 18%.

Flickr has a very large user base at 75 million, making its annual report a notable insight into which devices are most popular with the general public. Just like its top 25 photos of the year give us an idea of the photographic styles that appeal to the most people.

CAMS unveils new camera plates for small DSLRs and mirrorless cameras

02 Dec

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_5930146630″,”galleryId”:”5930146630″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Following in the footsteps of its successful Kickstarter campaign to fund the Pro Camera plate system, accessory manufacturer CAMS is looking to the crowdfunding platform once more to create scaled down plates for smaller DSLR and CSC bodies. The company hopes to raise $ 20,000 to fund a project that it says brings a host of new features to the plate and sling strap system.

The new CAMS standard and Mini Plates are designed to fit smaller camera systems while still allowing access to the battery compartment door so batteries can be changed without having to remove the plate. The plates also have their own storage slots for a spare SD card and to hold the hex key that fits the plate to the camera.

Those using Arca-Swiss type tripod heads will be able to mount the plate directly onto their tripod, while a further thread in the base allows the plates to attach to a standard 1/4in-20 tripod screw.

Here’s a quick intro to the new plates from the Kickstarter campaign:

A sling strap comes as an optional accessory and connects to the plate via a quick-opening attachment, while a hand strap can be used with the smaller lug close to the camera’s handgrip. In addition to the usual neoprene strap, the company is now offering Minima webbing strap and a Pelle leather version.

Prices start from $ 50 for either plate with no strap or $ 65 with a Minima strap. For more details, visit the CAMS Kickstarter campaign page or the CAMS website.

Ten Nikon D5 DSLRs will arrive at the International Space Station tomorrow

14 Nov

Back in August, NASA’s love affair with Nikon cameras made the news when the space agency ordered 53 unmodified Nikon D5 DSLRs that it would use on the International Space Station and for ‘training purposes’ here on Earth. Ten of those D5 cameras are scheduled to make it to the ISS this week.

Packed aboard the Orbital ATK OA-8 Space Station Cargo Resupply Mission that took off this Sunday at 7:19am Eastern time, and are scheduled to arrive at the ISS tomorrow morning around 4:50am (you can actually watch live coverage of the rendezvous on NASA TV starting at 3:15am).

Nikon tells us that NASA is “reusing Nikon lenses and accessories previously launch with the Nikon D4 and D2Xs cameras,” and are planning to keep the D5 cameras in circulation for 12-18 months. With any luck, the astronauts aboard the space station will use them to capture more images like these:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_9349612405″,”galleryId”:”9349612405″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

NASA’s relationship with Nikon began in 1971, when the Nikon Photomic FTN (a modified Nikon F) went to the moon with the astronauts of Apollo 15. Fast forward to 2008, and NASA ordered its first digital cameras for use in space, a set of six Nikon D2XS DSLRs, followed by an order for 11 Nikon D3S cameras in 2009, 38 Nikon D4 DSLRs in 2013, and another 10 D4s in 2016.

The only question now, I suppose, is when is the Space Agency going to replace its glass? NASA’s latest order of Nikon glass was placed in 2010, when 64 NIKKOR lenses were delivered to the space agency. If astronaut photographers are anything like us Earth-bound folk, that means they’ve been drooling over ‘better’ lenses than they currently have since about… three days after they got those lenses.

Vixari is the world’s most portable tripod, but it can still handle DSLRs

10 Nov

A new tripod called Vixari is attempting to launch on Kickstarter, where it is billed as “the world’s most portable tripod.” Vixari has an ultra-portable foldable design that’s only a little bigger than a smartphone, but despite its ultra-compact size, Vixari is still able to handle large cameras, including DSLRs that weigh up to 2kg / 4.4lbs.

Vixari isn’t the first portable tripod, but the team behind it claims that it is the most compact. The tripod features extendable legs that fold into the unit’s body, which itself doubles as a folding case. Each of the three legs have a maximum length of 105cm / 41in, while the body has three mounting options: a slot for smartphones between 6mm and 9mm in thickness, a mount screw, and GoPro tripod mount adapter. And since it can be used to trigger smartphones, it includes a Bluetooth remote shutter that supports Android and iOS.

The tripod body is made from polycarbonate, while the legs are made from aluminum alloy, the combination of which makes it durable and lightweight. The tripod will be offered in black, white, and dark blue colors, assuming it successfully makes it to market. Overall, Vixari measures 19cm x 6.5cm x 3.4cm / 7.4in x 2.5in x 1.33in and weighs 600g / 1.32lbs.

Kickstarter backers are offered the tripod, plus mount screw, mount adapter, remote shutter, and charging cable for pledges of at least £49 / $ 65. Shipping to these early bird backers is expected to start in February 2018.

To learn more or put down a pledge, head over to the Kickstarter campaign.

DxOMark: DJI Zenmuse X7 outperforms GH5, on par with top-notch APS-C DSLRs

09 Nov

Remember when the DJI Zenmuse X7 drone camera was released, and we said DJI had become a camera company without anybody noticing? You might consider the latest scores out of DxOMark proof of that assertion. The sensor testing company just released its review of the X7, ranking it above the popular Panasonic GH5 and on part with top-scoring APS-C sensors like the Nikon D7500.

Sporting the largest sensor yet for a DJI camera module, the X7 boasts a Super 35/APS-C sized chip that DxO discovered will hold its own against the leaders in that category. In fact, going through the rankings, you’ll find that only two APS-C sensors have ever scored higher than 86. And when you compare it to one of the top-scoring APS-C cameras (the Nikon D7500) and the often-drone-mounted Panasonic GH5, you see that DJI is not playing around:

As DxOMark points out in their conclusion, this is an impressive showing for the drone maker:

Thanks to an increase in its size as much as to technological advancements, the DJI Zenmuse X7’s sensor takes a significant step up in performance from the Zenmuse X5S sensor. In fact, it delivers results that compete closely with those from a high-scoring APS-C format DSLR, despite being housed in a camera that’s mounted in a stabilized gimbal and specifically designed for aerial photography.

Be sure to head over to DxOMark to read their full DJI Zenmuse X7 review. And then check out our own opinion piece about DJI’s transformation from a drone maker, into a full fledged camera company.

NASA just ordered 53 Nikon D5 DSLRs for the ISS and training purposes

27 Aug

NASA’s relationship with Nikon is as strong as ever, judging by the fact that the space agency just placed a massive order for 53 Nikon D5 DSLRs.

According to Nikon, NASA ordered the cameras as-is (no hardware modifications) and plans to use them for photography on the International Space Station, as well as astronaut training on Earth. The agency might make some changes down the line, but for now there’s no difference between the D5 cameras available to consumers and the ones being shipped to NASA.

This is the latest development in a long-running relationship between NASA and Nikon, which has provided the space agency with camera gear as far back as 1971 for the Apollo 15 space mission.

Most recently, Nikon provided NASA with 38 units of the Nikon D4 DSLR in 2013 and another 10 units of the D4 in 2016. The camera maker didn’t reveal whether NASA received any special discounts on its bulk order, but assuming NASA paid retail price, the cost could have exceeded $ 344,000 USD.
