SLR Magic is proud to announce the SLR Magic ANAMORPHOT-CINE 1.33x PL lens set for filmmakers which could be adapted to EF/F/mFT/E-mount via adapter.

As a commitment to the film industry, SLR Magic developed the SLR Magic ANAMORPHOT-CINE lenses to deliver the classic contrast, distortion, chromatic, color aberration, and flare characteristics of vintage anamorphic lenses, but with the convenience of a matched lens set without the hassle of aligning and matching lenses to the already popular SLR Magic Rangefinder with Anamorphot adapter combination.

To achieve the much loved scope aspect ratio, which gives a very pleasant, epic effect, filmmakers must crop off the top and bottom of standard 16:9 footage when using spherical lenses with modern digital cameras. As a result, 25% or more sensor/negative information is discarded.

This 1.33x anamorphic lens help filmmakers to maximize their image quality by preventing this loss of vertical resolution. The unique 1.33x squeeze factor uses the entire 16:9 sensor/negative area to achieve the desired 2.35:1 aspect ratio. The SLR Magic ANAMORPHOT-CINE 1.33x does this by compressing a 33% wider field of view to fit the width of the 16:9 sensor/negative without compressing image height.

The SLR Magic ANAMORPHOT-CINE 1.33x create a unique “artifact” such as horizontal lens flare, commonly referred to as anamorphic streaks, and may create slightly elongated bokeh. Over the history of cinema, these same stylish effects have contributed to the cinematic “look” of epic motion picture photography. Characteristics that shape this anamorphic “look” come from “front-mounted” anamorphic designs such as the SLR Magic Anamorphot while “rear-mounted” anamorphic designs have more suppressed anamorphic characteristics.

Optical prescriptions that appear to correspond to production lenses are of particular interest and over 400 are organized into the Optical Bench Hub. The Optical Bench Hub is probably the best place to start.

In addition to the Optical Bench there is an Optics Primer that people may find interesting reading.

The Optical Bench has a many features and if things aren't obvious as you play with it check out the Help button. The help is a little out-of-date, for example the Zoom and Focus slider features are quite new and not documented yet (but a lot of fun!).

To whet your appetite I'll attach a screenshot showing the recently announced Canon RF100mm F2.8 L Macro IS US.

did anyone tried the Olympus 9-18mm (4/3 mount) on the GH2 with an adapter? I am interested in buying one, just wanted to know your opinion on this before spending the money. The adapter I want to buy is the "cheap" Viltrox JY-43F (45€) plus the lens Olympus 9-18 (300€ used).

I think this lens would be nice Wide on the Blackmagic Cinema Camera also no?

Hobbyists, photo enthusiasts and professionals alike will be captivated by the M.ZUIKO DIGITAL ED 8mm f/1.8 PRO Fisheye lens' 180-degree diagonal angle of view. Like the M.ZUIKO DIGITAL ED 7-14mm f/2.8 PRO, this lens includes dustproof and splashproof construction, for unlimited wide-angle adventure. The lens is also compatible with a custom dome port for use with an Olympus underwater housing.

The M.ZUIKO DIGITAL ED 8mm f/1.8 PRO Fisheye lens is constructed of 17 elements in 15 groups and can capture high resolution at the very edges of an image, even at the maximum aperture of f/1.8. ZERO Coating minimizes optical flares and ghosting. The lens also comes with a fixed lens hood and a pinch-style lens cap LC-62.

From under the sea to the night sky, the record-breaking new M.ZUIKO DIGITAL ED 8mm Fisheye 1:1.8 PRO is an unprecedented opportunity to add stand-out creativity and a uniquely dynamic and abstract look to extremely wide-angle shots of the natural world. Unprecedented, because – in this category – the Fisheye PRO is the world’s brightest fisheye lens*. The super-large aperture ensures photographers top-notch optical performance in any conditions, especially in low light. The 2.5-cm minimum focusing distance (measured from end of the lens) and maximum magnification of x0.2 make it a logical choice for nature photographers with a passion for quirky perspectives and eye-catching bokeh.

But the Fisheye PRO is also ideal for fast-action sports photography; landscape, nightscape and sky panoramas; as well as crowds, interiors or architecture. For underwater specialists, it likewise opens up exciting new opportunities – it’s compatible with a range of accessories via the new underwater lens port PPO-EP02.

Like the other lenses in the M.ZUIKO PRO family, it’s extremely compact and lightweight, especially compared to equivalent D-SLR rivals. The build quality is top notch. In pre-launch tests, professional photographers were quick to praise the blur-free performance of the Fisheye PRO at both ends of the f stop scale. Light fall-off at the edges is negligible, as are both chromatic and comatic aberrations, particularly when compared to equivalent rival lenses.

Designed to provide both stunning HDR imagery as well as beautiful 4K, Canon U.S.A., Inc., a leader in digital imaging solutions, is introducing a new addition to its cost-effective UHDgc series of portable 4K broadcast zoom lenses — the CJ17ex6.2B. This lens supports 4K UHD quality optical performance and provides operators with a compact, lightweight, and highly portable form factor for easy integration into Houses of Worship, ENG, and commercial environments. With the addition of this lens, Canon further expands its lineup of 4K broadcast lenses, now at an industry-leadingi 18 models.

The CJ17ex6.2B features a wide-angle focal length of 6.2 mm and a 17x zoom ratio that brings the telephoto focal length up to 106 mm. The lens is also equipped with a built-in 2x extender that enables users to quickly double the focal length up to 212 mm while maintaining amazing image quality and fine details. The lens utilizes UD (Ultra-low Dispersion) lens elements, optimally arranged in a Canon proprietary optical configuration, providing superb color reproduction to the image’s peripheral areas by enabling the suppression of potential chromatic aberrations such as color bleeding and fringing. Special lens coatings on all elements combine with a number of optomechanical strategies on the interior of the lens barrel to help reduce ghosting and flaring. Like all Canon 4K lenses, the CJ17ex6.2B comes standard with a drive unit that contains 16-bit absolute value encoders for smooth cooperation with CG environments, as well as three 20-pin connectors for easy integration into virtual and robotic systems. In addition, the lens supports HDR and WCG compatible color gradation, producing images rich with vivid colors and details.

The CJ17ex6.2B lens is easy to maneuver and shoulder, with its compact and lightweight design, weighing approximately 4.78 pounds and measuring approximately 6.49 inches (w) x 4.31 inches (h) x 9.46 inches (l) in size. The lens itself is designed with optimally located handgrips to help minimize operator fatigue when shoulder-mount recording.

Availability

The CJ17ex6.2B 4K UHD portable zoom broadcast lens is scheduled to be available in June 2021*. For more information, please visit, https://usa.canon.com/broadcast.
