Prime Lenses used for shooting video on DSLRs benefit from a specific set of features, which the Samyang 10mm T3.1 VDSLR Lens with Micro Four Thirds Mount incorporates into this extremely wide-angle lens. It covers APS-C sized sensors and features an de-clicked iris for smooth exposure pulls. Built-in industry standard geared focus and iris rings allow you to use optional lens accessories such as follow focus units or lens motors.

A nano coating system is used to provide the lens with increased flare protection and improve contrast. For The lens features an aluminum housing, with 14 elements in 9 groups, including two aspheric elements and one low dispersion (ED) element. Focus and iris rings are manually controlled and a non-detachable, a petal-shaped, lens hood provides protection from flare and glare without using a matte box.

Related Questions and Answers

Q: 1. Is this a good lens for astrophotography? Is there a better choice for X mount?

A: Yes, the TTArtisan 10mm f/2.0 Lens (FUJIFILM X) can be used for astrophotography. This Rokinon 12mm lens would also be a good option: https://bhpho.to/3VYAv4j.

Q: 2. Looking for a wide angle to use when shooting my A7S II when shooting at 120 fps (which crops the sensor at 2.2) So the focal length would be about 25 mm? Will this remove most the fisheye bending?

A: This lens should create, on a full frame camera, a circular 180 view. When you go to 120FPS, the fisheye distortion will be unchanged for all that happens is that image is cropped and you are left with what is in the center.

Q: 3. 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: 4. "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: 5. Internal focusing for this cine version as well?

A: The lens has an internal focusing design, which means that the length of the barrel wont change as you focus, which is particularly important when shooting with a matte box.

Q: 6. 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: 7. That lens shouldnt be a MACRO lens?

A: To be called a macro lens, the image has to be recreated in a 1:1 ratio life size on the sensor. With this 100mm lens, focused at it's minimum distance of 12 does come close but not 1:1. I would say it is about 1:2 which may be close enough for you. If needed to get closer, I would use close-up lenses like these.

Q: 8. I do very little video. Will this lens provide quality still photos?

A: Lenses are agnostic optically as to whether they are shooting still or video: they give the same quality either way. Frankly, most any lens can do either. What differentiates is the feature set. AF, or manual, clickless stops, f/stops vs T/ stops, IS, etc, etc. That being said, this lens with create very good image quality, in stills or video. You will have to manually set the focus and the aperture.

Q: 9. Is this a full frame lens or APSC?

A: The TTArtisan 10mm f/2 Lens is an APS-C (crop frame) lens. They make the 11mm for full frame: https://bhpho.to/3cuznxf

Q: 10. Is it rectilinear corrected?

A: It is not. I believe you may be referring to this lens instead, the Samyang 12mm f/2.0 NCS CS Lens for Sony E-Mount (APS-C) (Black) which is not a fisheye lens but a wide angle lens, BH #SA122SEB. https://bhpho.to/2MeAEiK
