The 135mm T1.5 AS UMC VDSLR II Lens for Sony E-Mount from Samyang is a manual focus prime lens. It provides a maximum aperture of T2.2 for effective low light capture and shallow depth of field control and a 9 blade iris for attractive bokeh. Optimized for cinema and video applications, the focus and aperture control rings are outfitted with industry standard gearing, which provides an interface for working with a traditional follow focus. The aperture control ring has also been de-clicked, which enables smooth iris pulls. In addition, bright aperture and distance markings are printed on the lens barrel facing laterally to facilitate easier control by a focus puller. The lens has a minimum focus distance of 2.6'. Internal focusing minimizes the effects of focus breathing, and the lens is composed of 11 elements in 7 groups. A lens multi-coating helps to improve light transmission reducing flare and ghosting. The filter thread diameter for attaching sunshades or filter rings is 77mm.

Each of the VDSLR II lenses will offer the same position of their geared focus and aperture rings so that follow focus and other rig accessories won't need re-adjustment when swapping lenses. Also, each lens is tested to be color matched with the other lenses in the series and provide the same color and contrast when shooting video, allowing you to add lenses to your kit over time without worrying about the color of your image changing significantly when swapping lenses. As an aid to focus pullers, the lenses are marked with focusing scales on each side of the barrel for easier adjustment from both sides of the camera.

The 135mm T2.2 is part of the VDSLR II series of cine lenses, sharing characteristics and features that unify the series and make it easier for users to swap out lenses when shooting video. Each VDSLR II lens provides aligned focus and aperture rings so that readjustment of the follow focus is not necessary when switching lenses. Also each lens has been tested to match color and contrast for a consistent look and less potential post-processing. Finally, all lenses from this series print focus scales on both sides of the lens barrel for ease of use from each side of the camera.

Related Questions and Answers

Q: 1. Is this the same lens as Rokinon?

A: Rokinon and Samyang lenses are manufactured in the same factory.

Q: 2. Is this the identical sister to the Rokinon version? I understand the branding is different.......thanks

A: These two lenses are identical.

Q: 3. Does the lens transfer the EXIF date to the camera? i.e. Would Adobe Lightroom know the photo was taken with a Sony a7 + Samyang 135/2 lens for a profile correction?

A: There is no electronic connection between the camera and lens. Exif will have exposure and camera type only. The same as if you were using any vintage lens.

Q: 4. Is this newer than the DS version?

A: The Samyang 135mm T2.2 AS UMC VDSLR II and the Rokinon 135mm T2.2 Cine DS Lens were announced the same day, January 12, 2015.

Q: 5. Same quality as Rokinon DS cine? If these Samyang VDSLR II lenses are identical to the Rokion DC cine lenses, it would be great if there were lens kits and more models, like the Rokinon DS line.

A: The Rokinon line is the highest level of quality of image, finish and features that this lens manufacturer makes. I would imagine in a test, there would be a slight edge with the Rokinons for better contrast and flare control over the Samyangs. And the feature that would be essential on productions with an focus puller is the Dual Side of the Rokinon DS line. However, if you are a single shooter, you could save your money for other stuff.

Q: 6. What is the weather-proofing on this lens? Can this be used in rainy conditions?

A: It is nowhere as well weather proofed as the Canon L lenses for example.It is very well built, but I would avoid getting it wet if possible.At least, I wouldn't be game to get mine wet if I can avoid it.A few drops shouldn't be a problem though.

Q: 7. Will the exposure be shown (caculated) when used on the A7II?

A: Yes in. M. A modes.

Q: 8. Will this lens fit and work with my Nikon D5200 ?

A: Yes it will. It is a full crame lens. It will work as 50mm on fx bodies and as 75mm on dx bodies such as d5200. Note that the version t1.5 is a cinematography lens. If you need it for photography you should get f1.2 version.

Q: 9. does TTL work with this lens?

A: Because this is a manual lens, the Samyang 135mm f/2.0 ED UMC lens does not have electronic contacts for communicating with your Sony E-mount camera. However, as TTL is mostly based on metering, TTL should not be adversely affected by this lens or its lack of electronic communication.

Q: 10. Does this lens require an adapter to mount on the A7r?

A: As the Samyang 135mm f/2.0 ED UMC Lens for Sony E Mount, B&H # SA1352SE, uses the Sony E-mount on the rear of the lens, the lens would directly attach to the Sony Alpha a7R Mirrorless Digital Camera without the use of an adapter.
