Preston Lens Mapping
Posted 21 June 2010 - 01:40 PM
We learned today that the Arriflex Master Zoom is not a linear lens, and as such it can not be mapped properly. I know that there are other lens out there that have this same issue. I would love to put together a list of lenses to include with our kits showing what will present problems to try and save the AC's some hours of troubleshooting trying to figure out what is wrong when indeed everything is actually OK.
BTW - the way to check and see if the lens is linear or not, is when you calibrate you will be asked to hit INF and 5 marks throughout the barrel. If those 6 marks are spot on, but everything between them is off, then the lens must not be linear.

RED Pro Primes (from 18 to 100) can't be mapped with the HU3. I have asked Preston to have a look at this problem, I have not received any update or news about this yet.
Thanks for starting this thread.
