I'm 1st ACing a feature right now and we got off of an EXT night shoot (very cold out) and my lens markings are mostly off. It's a set of CP2's that we rented from an owner/ operator, and one of the lenses is off between 2"-11" and another is off by a foot. Never had to deal with this before, but I'm just wondering what I should do? Will a rental house take them in and calibrate them? I have a day off tomorrow so I'm going to try and get it solved then.

Thanks!

Is it the lenses or the camera? Could it be back focal distance that's wrong? Take everything to the shop, all the camera bodies and lenses.

Flange depth is likely off, but as it is the CP.2 you don't say if they are in PL mount or Canon. You need to go to a facility that can check what you've got properly. Abel Cine Tech can do this for you in either mount. But you need to talk to the owner of the lenses first -- we can't touch someone else's gear without permission.

They're PL mount CP2's and we're shooting on the RED. The owner/ operator is a friend so I'll contact him and get in touch with you. Thanks!

No problem. Easy for us to set.
