While the 12 mm and 15 mm lenses are already available with a VM-Mount the 10 mm focal length is completely new. As these extreme wide lenses are challenging a fast and smooth communication between lens, camera and photographer, which is extremely important.

If enabled the camera changes automatically in magnifying mode during focusing which allows highest accuracy. All lens-relevant data such as focal length, aperture and focal distance are transmitted to the camera. This data is shown in the view finder/display and used for metering and image stabilization.

The selective aperture control system for full frame is used for the first time in this lenses—a vital feature for film makers as it allows a stepless and soundless aperture control.

Sony Electronics, a worldwide leader in digital imaging and the world’s largest image sensor manufacturer, has today introduced a new full-frame lens for their E-mount camera system, the Planar T* FE 50mm F1.4 ZA (model SEL50F14Z).

This 50mm prime lens features a large F1.4 maximum aperture that offers impressive contrast and outstanding resolution that are hallmarks of the ZEISS® brand. It produces these consistently strong qualities throughout the entirety of the frame – from center to corner – and at all aperture settings, even while shooting wide open at F1.4. The cutting edge optical structure includes high-precision AA (Advanced Aspherical) and ED (Extra-low Dispersion) glass elements that reduce spherical and chromatic aberration, as well as a ZEISS® T* Coating that minimizes flare and ghosting creating the classic ZEISS® clarity. Additionally, its Planar design ensures minimal distortion.

The large F1.4 maximum aperture of the FE 50mm F1.4ZA lens provides a level of brightness and speed that are advantageous for dimly lit indoor shots, night scenes, and portraits, while its 11-bladed circular aperture allows for stunning “bokeh”, or background defocus, in images. The lens also features an aperture ring with an adjustable ON/OFF switch, an AF/MF focus mode switch, and a dust and moisture resistant design¹, further increasing its functionality.

The new lens is also equipped with a ring drive SSM (Super Sonic wave Motor) system, which allows it to efficiently lock focus with speed, precision and in near silence, making it particularly useful for shooting movies.

Pricing and Availability – FE 50mm F1.4 ZA Lens

The new FE 50mm F1.4 ZA lens will ship this July for a retail price of $1,500 US and $1,950 CA. The new FE interchangeable lens will be sold at a variety of Sony authorized dealers throughout North America.

SIGMA Corporation is pleased to announce the upcoming launch of interchangeable lenses for the Canon EF-M mount digital camera series with APS-C image sensors. SIGMA will gradually introduce the lenses as members of the Contemporary line.

The new Canon EF-M mount models will feature a newly and exclusively developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed. In addition, these lenses will be compatible with Servo AF and lens aberration correction.

The lineup will include the Contemporary line set of three prime lenses 16mm, 30mm, and 56mm. While retaining the compact, lightweight and outstanding image quality concepts of the Contemporary line, this new large-aperture lens series covering from wide to mid-tele angle provides the amount of bokeh and admirable brightness expected from F1.4 to be enjoyed on Canon EF-M mount cameras.

Key features

• Impressively compact construction with image quality rivaling SIGMA's Art line.\ To achieve such a compact construction, the lens design is considered based on the capabilities of the camera body function to correct peripheral light amount and distortion. A compactness and lightweight construction combined with superb image quality is achieved.
• Smooth AF ideal for video shooting\ The combination of optical design for video AF and use of the stepping motor enables smooth and quiet autofocus. This lens is also compatible with the camera's Face + Tracking AF.
• Data loaded for compatibility with in-camera aberration correction\ The lenses will be fully compatible* with in-camera aberration correction, which includes corrections for peripheral illumination, chromatic aberrations and distortion. By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.
• Available Mount Conversion Service\ This service converts the mount of SIGMA lenses to that of a different camera body, allowing photographers to continue using their favorite lenses over the long term regardless of camera system.

Only when the camera is compatible.

1952, smooth as silk. Review shortly.

Announcement soon.

The ZEISS Ventum 2.8/21 offers outstanding optical quality in a compact and rugged aluminum housing. The extremely fast, fixed-focal-length lens for Sony's E-Mount was primarily developed for use with drones. Lenses used for this purpose must be as small and light as possible, yet still offer outstanding image quality. Thanks to its compact design and the use of a fixed-focus setting, the weight of the ZEISS Ventum 2.8/21 has been reduced by 50% compared to the Interlock Compact 2.8/21. This reduction in weight allows drones to fly longer, resulting in greater efficiency.

The lens is equipped with the E-Mount and is compatible with large area-scan and line-scan sensors with an image circle of up to 43 mm and a pixel size starting at 2.8 µm. The aperture can be adjusted on the lens by 1/3 f-stops from F2.8 to F22. The locking and torque of the aperture ring are designed to prevent accidental adjustment due to vibrations or the movement of the drone through the air.

Drones are important tools in modern surveillance applications, and will become increasingly common in the future. The ZEISS Ventum 2.8/21 offers unmatched data quality for applications such as cartography, creating three-dimensional models, inspections, surveys or monitoring project progress from the air.

The lens also provides reliable data in stationary applications such as the large-scale monitoring of events, power plants, open-cast mining, landfills or construction sites.

Leica Camera sets an even higher benchmark for the Summicron-SL family with another top-flight lens: the Leica APO-Summicron-SL 50 mm f/2 ASPH. Often seen as the standard focal length for full frame cameras, this new 50 mm promises a level of performance high enough to demand a spot in the gear bag of any photographer looking to take advantage of the L-Mount system. Whether the task at hand is travel photography, studio work, architecture, landscape, portrait or documentary photography, the Leica APO-Summicron-SL 50 mm f/2 ASPH. is the new go-to L-Mount lens, delivering results that satisfy even the most discerning photographer.

The new APO-Summicron-SL 50 mm f/2 ASPH. consists of twelve expertly designed lens elements – three of which have aspherical surfaces for correcting optical aberrations – arranged in 10 groups, to achieve ultimate image quality. This lens allows photographers to seamlessly capture natural skin tones, smooth bokeh, outstanding contrast and consistent sharpness from corner-to-corner of its distortion-free images. The APO-Summicron-SL 50 mm f/2 ASPH. keeps chromatic aberrations in check by utilizing apochromatic corrections, where it earns its “APO” designation. This ensures that all colors of the light spectrum are accurately passed through the lens and fall on the same focused point on the camera’s sensor, so the photographer can know that they will get maximum detail in all situations without optical artifacts like distracting green or purple color fringing. To accomplish this, nearly all elements used in the construction of the lens are made from specially formulated, high-quality glass types for the highest possible light transmission. The end result marks an advancement in imaging performance with the venerable “Leica look” and signature rendering.

The thoughtful construction of all Summicron-SL lenses pays special attention to the prevention of stray light and reflections. The optical and mechanical design coupled with high-quality lens coatings serve to maintain the exceptional quality expected from a Leica lens. With their effective weather sealing against dust, moisture, and water spray, combined with an Aquadura coating of the exposed lens surfaces preventing water from beading, the Summicron-SL lenses can be confidently used in most extreme weather conditions.

The autofocus drive of all Summicron-SL lenses employs powerful and robust stepping motors with DSD® (Dual Syncro Drive™). The entire focus range of the lens – from close-up to infinity – can be fully traveled in just about 250 milliseconds to ensure spot-on focus that keeps up with moving subjects. Summicron-SL lenses also take an innovative approach to manual focusing technology, featuring a totally new focus ring construction. With this new method, a ring magnet with alternating polarization is embedded in the manual focusing ring along with a sensor that monitors the status of the magnetic field. The magnetic field changes its polarity when the ring is turned, and the sensor transmits the pinpoint details of user input that drives the focus. This intricate process happens near-instantaneously at the simple turn of the focus ring, enabling even faster and more precise manual focusing with a nicely dampened and weighted feel. The photographer can quickly access the finest manual focus micro-adjustments when they need it, right at the reach of their fingertips

Thanks to the L-Mount standard, the new APO-Summicron-SL 50 mm f/2 ASPH. is also fully compatible with cameras manufactured by partners of the L-Mount Alliance who use the lens mount developed by Leica. The APO-Summicron-SL 50 mm f/2 ASPH. is on sale now at Leica Stores, Boutiques and Dealers for $4,495.00.Leica has announced its APO-Summicron-SL 50mm F2 lens, which is designed for the L-mount system. The lens is smaller, lighter and, as you'd expect, cheaper than Leica's F1.4 variant.

The 50mm F2 has twelve elements; three are aspherical and eight use an anomalous partial dispersion (APD) design to reduce chromatic aberration. Dual stepping motors can move the focus elements from their minimum focus distance to infinity in 250ms, according to Leica. The minimum focus distance is 0.35m (13.8"), with a 0.2x maximum magnification.

As one would expect from Leica, the lens is sealed against dust and moisture, and an 'Aquadura' coating prevents water from collecting on the front element.

The APO-Summicron-SL 50mm F2 lens is now available for $4495.
