Related Questions and Answers

Q: 1. Is that lens compatible with BlackMagic URSA?

A: This lens is compatible with Blackmagic URSA cameras with an EF mount.

Q: 2. Do you need to have lens support?. Thank you.

A: The PL mount is robust and meant to securely hold heavy lenses. This lens is not too heavy, only 4 lbs. However, I would not normally use this lens without support. The leverage created on the lens mount by the camera fighting the lens goes right to the lens mount, the most crucial adjustment on the camera. The mount and the lens are set to tolerances of plus minus 5 10,000 so you do not want strain that mount at all. If that adjustment is off, all your footage will be soft or the lens marks will be off as well. So if the camera and lens never move, you probably will be OK. But if you are moving, put a support under it.

Q: 3. With a supporter cinema camera, like the C500 II, or supported EOS cameras, like the R3 and R5C with WFT-R10A, can this lens be controlled using the browser remote function?

Q: 4. If this lens is closed down to higher than T3.95, will it hold transmission through the zoom range or will it still ramp at the long end?

Q: 9. How would I power this lens with a Canon C200 EF mount? Is the expansion unit EU-V2 required and is that compatible with the C200?

A: This lens cannot be powered with the C200... It uses a 12-Pin Control port for control and power and can not be controlled or powered directly from a canon c200. EU-V2 is an expansion unit strictly for the c500MK2 and will not work on a c200.
