Q: 1. Would this lens work with a Mitakon Zhongyi turbo II lens adapter attached to a Blackmagic pocket cinema camera? Can I control the focus, and the aperture? Thanks.

A: It appears that the Mitakon Zhongyi turbo II lens adapter is a manual adapter, which means there would be no electronic communication between the lens and the camera. You would not be able to adjust the lenss aperture, and you would need to focus manually.

Q: 2. can I use it with the C100 mark II ?

A: EF lens mount, so yes.

Q: 3. Will it work on a Canon EOS Rebel T6???

A: Jorge, it will work, but be aware because of the crop factor, it really won't give you the true results of a 17-40mm. That said, I have one that I use on full frame bodies, and it's a nice light lens with reasonable quality.

Q: 4. Will this lens work on the t6i camera?

A: This lens will be compatible with the Canon T6I.

Q: 5. I use a Canon 6D, and I'm considering buying this lens. I'm a bit concerned with the fact that it only opens up to f/4. Should I be concerned? Or would ISO be able to make up for it without reducing image quality?

A: I have the 6D and the 17-40mm f/4L lens and they work great together. The full frame sensor in the 6D lets you crank up the ISO without adding too much noise and the noise reduction features in Adobe Lightroom virtually eliminate any noise that is present. I routinely shoot indoors in low light with no flash and have had no trouble. I switched to the 6D 2 years ago and it took a little while to get used to the fact that I could crank up the ISO to 12000+ and still get great images.

Q: 6. How well does this lens work with the Canon R mirrorless?

This should be done with a metric ruler, making sure the ruler passes through the lens' center point. The appropriate cap size is the diameter in millimeters.

Q: 9. I have a canon 60d and in the future would like to upgrade to a fullframe camera. Would an Canon Extension Tube EF 25 II benefit me to get the wide angle lens ?

A: The Extension Tube EF 25 II is designed for lenses of 50mm and above, it will not work with this lens which is a 17-40mm. That being said it is a great wide angle lens that you can use on your 60d now and it is also compatible with Full Frame Canon Cameras like the 5D Mark IV and 6D for when you upgrade in the future.

Q: 10. would this fit the 5d mark ii full frame?
