Leaked photo hints at Samsung Galaxy S9 with variable aperture lens

13 Jan

Samsung has confirmed its upcoming new flagship smartphone, the Galaxy S9, will be launched at MWC in Barcelona, so we’ll have to wait until late February to know for sure what features and specifications the new model will have to offer. That said, Reddit users have found an image of an alleged S9 retail box that is already giving us a good idea of what to expect from the new flagship.

From a photography point of view, the most interesting information on the box is the “F1.5 / F2.4” aperture specification, indicating that the Galaxy S9 might come with the same stabilized variable aperture 12MP camera as the China-only W2018 flip-phone.

On that phone, the camera switches between F1.5 and F2.4 when it senses there’s enough light around in an attempt to capture the background as much in focus as possible. Whether or not that really makes a lot of sense, given the small image sensors in smartphones, is for you to decide. In any case, the F1.5 aperture value is the fastest on any current smartphone, which should be appealing to any low-light shooter.

If the specifications on the box are true, the S9 camera will also record super slow-motion videos, hopefully at similarly high frame rates as the latest Sony devices. In addition, there is a pair of AKG-powered stereo speakers, and we’d expect the S9 to come with Qualcomm’s latest Snapdragon 845 chipset.

Most most of the additional information on the retail box is quite similar to the current S8 model: the S9 screen will have a Super AMOLED panel with Quad HD+ resolution (1440 x 2960 pixels), 18:9 aspect ratio, 4GB of RAM, 64GB of internal storage, and an 8MP front camera, all wrapped up in an IP68 water and dust resistant body.

Samsung’s new W2018 flip phone features a variable aperture F1.5-F2.4 lens

02 Dec

Samsung just announced something that looks like it belongs in the mid-2000s… but looks can be deceiving. Meet Samsung’s new flip phone: the W2018. Announced earlier today at an event in Xiamen, China, the followup to the W2017 is an Android-powered flip phone that boasts smartphone-caliber specs. In fact, the 12-megapixel rear camera is nearly identical to the one found in the Galaxy S8, featuring dual pixel autofocus, optical image stabilization and 1.4?m pixels.

It does differ in one very interesting way though.

Not only does the W2018 boast an F1.5 aperture—the brightest you’ll find on a phone—that aperture is actually variable, switching between F1.5 and F2.4 when it senses there’s enough light around. In this way, the phone automatically captures as much of the background as possible.

You can see the trick in this close-up video uploaded to Weibo by Jason Wang:

Rumors have been floating around that the Galaxy S9 will feature a variable aperture F1.5 lens; as you might expect, the appearance of the selfsame lens in another Samsung phone makes us pretty confident that will, indeed, be the case. As to whether or not you ever really need to ‘stop down’ a smartphone camera lens… that’s another topic entirely.

Like the W2017 before it, this phone will first be released in China, comes with a bunch of “VIP” perks like free tech support, and will probably cost upwards of $ 3,000… no, we didn’t add another zero.

Syrp introduces Super Dark 5-10 stop variable ND filter

13 Dec

Accessories brand Syrp has announced a new variable neutral density filter that will appeal to those who like to create very long exposures. The Syrp Super Dark Variable ND Filter operates between five and ten stops (ND32 to ND1024) and provides stop-markings on the rings so photographers can measure exactly how much light they are cutting out.

The company says it has reduced the range of densities the filters create to avoid the ‘X’ interference effect that is common with one to ten-stop filters. The filter can only be rotated within ‘safe’ limits, and Syrp has used ‘hard stops’ to prevent the forward ring being turned too far.

The filters come in 67mm and 82mm sizes, and each is packed with a pair of step-up rings to allow them to fit to smaller lenses. The forward ring of each is also threaded so further screw-in filters can be stacked in front of them, and the bezel is moulded to allow a regular lens cap to be fitted.

The filters cost $ 169 for the 67mm version and $ 209 for the 82mm version, and both come with a protective leather zip-up holder. For more information see the Syrp website.

Manufacturer information

Introducing the New Super Dark Variable ND Filter!

With 5-10 stops of adjustable exposure control, the Syrp Super Dark Variable ND Filter is a must-have tool for any photographer’s gear bag and is available for pre-order from today, with a planned shipping date of the 15th of December. The Super Dark is available in two sizes and includes hard stops at the minimum and maximum ends for reducing X-pattern.

Long exposures are fundamental to landscape photography as they capture the effect of time passing, giving your images an expressive and often surreal look. They also add a creative element to your time lapses making them more fluid and giving them a dreamy effect. Silky smooth waterfalls or glassy lakes can be captured in full day light with just a simple twist of the filter to allow you to slow your shutter speed and record long exposures.

Both the Small and Large Filter Kits come with a genuine leather carry case to house the filter and ensure it stays protected from dust and scratches. Our Super Dark Variable ND Filter provides exposure reduction of 5 (ND32) to 10 (ND1024) stops using a smooth, adjustable front ring. The filter also has a front thread so you can easily stack filters if needed and will fit your regular lens cap.

Included in each Filter Kit are two step up rings for maximum compatibility with the range of lenses in your kit. The Large Kit (82mm) has 77-82mm and 72-82mm rings and the Small Kit has 58-67mm and 52-67mm rings. An invaluable tool for time-lapse, the Super Dark creates a more natural and fluid transition between frames, reducing the appearance of moving elements’ flickering and stuttering.

Sony announces the PXW-FS7 ll with electronic variable ND filter and new handling features

10 Nov

Sony is preparing to release an updated version of its popular PXW-FS7 professional video camera that will feature an electronic variable neutral density filter that automatically compensates for exposure shifts of between two and seven stops. The filter can adjust itself so that apertures and shutter speeds can remain constant even when light intensity changes quite dramatically – thus maintaining the ‘look’ of the video. The new feature also allows aperture changes that alter the depth of field during recording without affecting the exposure of the footage.

The new camera doesn’t replace the existing FS7 as Sony says it will retain both models in the range to give videographers a choice. The new model will cost more than the original, so there will be models to suit different budgets.

Another new feature of the FS7 ll will be a locking collar around the lens throat that allows E-Mount lenses to be fitted directly to the camera without the need to twist them into place. The lens can be offered up to the throat and the collar rotated to lock it into place. This, Sony says, makes changing lenses much quicker as lens support rigs won’t need to be taken off to complete the lens switch.

Sony has altered the shoulder mount and the viewfinder so that they can be adjusted without tools, using wing nuts and finger screws to secure them in place. The monitor arm and the micro holder can now be switched for left-eye viewers, and the number of external assignable buttons has increased from six to ten.

The camera can accept A-mount lenses via an adapter

Like the FS7 the new FS7 ll uses a Super 35mm format sensor and can record 4K and full HD video at a range of frame rates up to 180fps and in a wide range of formats.

At the same time Sony announced the FS7 ll it also announced a new kit lens for the FS7 series and a G-Series 256GB XQD card with a 400Mbps write speed. The new lens is the SELP18110G 18-110mm f/4 power zoom with Optical SteadyShot built-in. Although Sony had said originally that the lens would be suited to be paired with the SEL14TC and SEL20TC teleconverters it has now announced that it will not in fact be compatible.

The Sony PXW-FS7 ll is due to arrive in January 2017, and the company has yet to release pricing information (the current model costs about £8000/$ 8500). For more information visit the Sony Pro website.

Sony Expands FS Series with New FS7 II Camcorder

New Model Delivers Advanced Features for creative Documentary and Indie Production with Electronic Variable ND Filter, Lever Lock Type E-mount and Refined Mechanical Design

Sony is expanding its FS Series Super 35mm professional family with the addition of the new FS7 II camcorder. The new model builds on the original FS7’s strengths by adding advanced features including Electronic Variable ND technology, a lever lock type E-mount, and a new mechanical design for faster and easier set-up.

Since its introduction in 2014, the FS7 has become one of the most widely used cameras in a range of production applications, and the original model remains in the Sony line-up. The new FS7 II now gives creative professionals a broader range of creative tools, with new features all based on end user feedback.

The new FS7 II camcorder is designed for long-form shooting and production applications, especially for documentaries and independent filmmaking. Amongst the many enhancements outlined below, the FS7 II can also record in BT2020 colour space, hence making it ideal for today’s 4K broadcast productions.

Electronic Variable ND Technology

The camcorder’s Electronic Variable ND Filter system, combined with its large sensor, delivers greater exposure control, with the option of preset or variable operation modes. Variable ND mode (clear + 2~7 stop range, in seamless transition steps up to 1/128) allows the user to vary the density of the ND filter during shooting and to transition seamlessly between steps. This also ensures an optimum motion delivery by maintaining desired shutter speed.

The camera’s expanded ND operations enables fine exposure adjustment by relegating iris to set depth of field, prevents soft focus caused by diffraction, and prevents colour shift caused by stacking multiple external ND filters.

The camera can compensate for exposure fluctuation caused by iris control while adjusting the depth of field. Users can adjust exposure while keeping the same bokeh in changing shooting or lighting environments.

Preset mode lets users assign three ND settings to the filter turret, useful in selecting the most appropriate filtration range for changing light conditions, for example. Auto ND mode is also available allowing exposure to stay at a fixed level while adjusting the depth of field with iris control.

E-mount (Lever Lock type) for professional shooting

The FS7 II revisited E-mount (lever lock type) gives users the ability to change lenses by rotating the locking collar rather than the lens itself, which means that in most cases lens support rigs don’t need to be removed, saving time during a production. The new E-Mount has been designed for demanding applications in the professional environment and will fit any existing E-mount lenses in the market and other mount lenses with an adapter. The new FS7 II camcorder also supports Sony ? Mount System, which includes more than 70 lenses.

Mechanical Design Enhancements

Like its counterparts in the FS Series family – the FS7 and FS5 models – the new FS7 II features several design and ergonomic updates for comfortable and functional use in the field. These new features are based customer feedback around the FS7.

The FS7 II “tool-less” mechanical design lets users make on-the-fly changes to the camera’s set-up and operation. For example, no tools are required to adjust the Smart Grip or viewfinder positions.

The detachable viewfinder eyepiece, which comes with a pop-up hood, provides a third stabilizing contact point when shooting handheld. Durable square section rods and lever-clamps on the LCD and camera body provide simple and precise front-to-back VF adjustment while retaining level positioning.

New Sony 18-110mm Sony G lens

Sony also introduced a new E-mount, Super 35mm lens specifically designed for documentary and motion picture production.

The new lens, model E PZ 18-110mm F4 G OSS, covers Super35mm and APS-C sensors. Compact and lightweight — 2.4 lbs (1.1Kg) — with an 18 to 110 focal range (6x zoom) it uses a new fully mechanical/servo zoom switchable system, capable of snap zooms and entirely devoid of lag. The focal range is optimised for Super 35 and APS-C sensors.

The lens is compatible with Sony ? Mount System cameras, including the ?7 series interchangeable-lens cameras and professional Super 35mm 4K camcorders like the FS7 or FS5. Although perfectly suited for still image taking, filmmakers will fully appreciate the lens’ extended creative capabilities for shooting motion images.

The lens benefits Smooth Motion Optics (SMO) design from Sony, which is developed to optimise performance during motion image capture. This lens design eliminates undesirable characteristics and artifacts that do not affect still image taking, but can severely limit a lens’ usefulness for motion shooting, such as:

  • Ramping: F stop gradually diminishes when zooming tight
  • Not holding focus while zooming
  • Breathing (angle of view variation while focusing)
  • Optical axis shift (image moves in the frame while zooming)

*Due to a change in the SELP18110G specifications it is no longer compatible with the SEL14TC and SEL20TC teleconverters.

XQD Cards

The FS7 II supports the XQD memory card format, designed for capturing and transferring high-bandwidth, high resolution files. The newest XQD card from Sony, QD-G256E — with an industry first 256 GB capacity — enables recording time of approximately 45 minutes at 4K 60P and 3.5 hours at 2K 30P. Combined with a read speed of 440MB/s and write speed 400MB/s, users can shoot for longer without needing to change media cards.?

The FS7 II is planned to be available in January 2017. For more information, please visit the product page.

Kipon launches EF to Sony E adapters with built-in variable ND filter

29 Oct

Chinese lens and accessory maker Kipon has introduced an adapter that includes a variable neutral density filter, primarily for video shooters. The filter is placed between a Canon EF-S mount and a Sony E-mount body. The Kipon EF-S/E AF ND retains the autofocus and image stabilisation features of the lens, according to the company, and EXIF data is communicated so it can be recorded in the image files. The adapter also allows manual focusing of the lens to trigger MF assistance features of the camera – such as peaking or magnification.

Kipon has produced adapters that contain graduated neutral density filters before but this is the first that has a variable ND filter. The filter is turned via a wheel that sticks out of the barrel and is marked with values between 1.5 and 7 f-stops. The idea of the adapter is that wide apertures can be used with shutter speeds appropriate for shooting video – as well as for stills shooters who want a shallow depth of field outdoors on bright days.

The adapter features an EF-S mount, so that it can use both EF and EF-S lenses but covers the full frame image circle for use on a7 series cameras.

The company suggests that the selling price should be 45,000 yen before tax, which is approximately $ 430.

You can read more about the adapter, including camera compatibility, on this translated version of Japanese agent Focus Workshop’s website.

Kenko-Tokina launches NDX variable neutral density filter

08 Aug

Kenko-Tokina has announced a variable neutral density (ND) filter that can be adjusted fro ND2.5 to ND1000. The Kenko NDX filter can darken the scene by anywhere from 1.3 to 10 EV. The filter allows the use of wide apertures while keeping the correct exposure within the shutter speed range of your camera, or of very long shutter times to emphasise motion. The company suggests its use for shooting video with shallow depth-of-field, for instance. Its variable nature allows the amount of filtration to be reduced for focusing, then increased to the desired amount, without having to remove the filter. The filters can vignette when used with lenses wider than 28mm equivalent and are available in 77mm and 82mm filter thread sizes.
