Q: 2. will this fit a canon xa20?

A: Sorry, but the Canon XA20's lens is not removable so there is no way to mount this Kowa lens. Since 25mm is very telephoto on the XA20's 1/2.84 HD CMOS Sensor, you might consider this tele converter that you mount on the front of the XA20's permanent lens.

Q: 10. Should my focus ring be more accurate? When my focus ring is set to 7' focus is actually at 5'. When I set to 4' focus is 2' 8 . I do tend to measure my manual focus lenses and this is my first I feel I can't trust. I do feel infinity focus seems a bit soft, is it possible I'm not able to get infinity focus if the actual focus distance is shorter then marked? Wondering if I should return... anyone else test the focus ring accuracy?

A: In my decades of being a motion picture camera assistant, this was a situation the we had to look our for. The problem is either the lens is out of collimation or the lens mount flange depth is off. If both are correct, Infinity is Infinity and 5' is 5'. I would suggest that it is the lens and that you should exchange it if you bought it from B&H less than 30 days ago.Contact B&H Customer service to do so. B&H Customer Service Contact: https://bhpho.to/2caRE5L. If the lens comes back and you still have an issue or you purchased longer than 30 days ago, take or send the lens and the camera to a camera service center.
