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. "APS-C Coverage" means it wil produce vignetting on a Full Frame sensor or means that the mount is EF-S?

A: That is correct. This lens is only able to cover an APS-C sized sensor. It is not compatible with a Full Frame camera and will give you substantial vignetting.

Q: 3. what does vdslr stand for and mean?

A: This lens is a video lens. Therefore the VDSLR stands for Video Digital Single Lens Reflex.

Q: 4. will this lens fit my canon eos rebel?

A: The Samyang 10mm T3.1 VDSLR Lens with Canon EOS Mount is designed for use on a Canon APS-C camera like the Rebel. It will work perfectly.

Q: 5. 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: 6. How does this compare to the 50mm f 1.4 lens (SY50M-E) besides the unclicked aperture?

A: If you are doing video and particularly if you have a focus puller, you want this lens. Much needed features of a video lens besides the de-clicked aperture is the geared rings for a mechanical interface with manual or motorized controls plus horizontal focus and aperture scales for easy reading by the camera assistant. The 50mm f 1.4 lens (SY50M-E) is a still photo lens thus does not need these features.

Q: 7. I do very little video. Will this lens provide quality still photos?

A: While this is designed as a Cinema lens, meaning that it has a de-clicked aperture and gear rings for follow focus systems, you can still take photos with it. Keep in mind though this is a fully manual lens, it will not work with your cameras AF system for still photos.

Q: 8. is it compatible with 70d?

A: The Samyang 50mm T1.5 VDSLR AS UMC Lens for Canon EF Mount is perfectly compatible with the 70D. Be aware this gives on a APS-C sensor camera a slightly telephoto perspective along with being manual aperture and focus only.

Q: 9. How bad is the focus breathing on this? I have the 85mm and it's pretty heavy.

A: On this Rokinon 135mm Cine DS model, the breathing is minimized.

Q: 10. 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.
