Hi Chris, have you read the anamorphic guide by Andrew, so to have an idea of some important characteristics concerning the compatibility of your gear (camera+lenses+anamorphic lens) & what the result may be? If not, I suggest you'll do. Send me a pm. From my small experience, Panasonic LA7200, Century, or Optex will fit you most and you'll avoid the cost for a clamp, as the need just a normal step-up ring to adjust the anamorphic on the taking lens. I have the last 2 (but for use on m4/3) and I'm very pleased with the results. Right now I'm waiting to receive the D610 so to make a test on FullFrame too. Also add to your budget some money for close-up filters (diopters) and you will need of course a filter clamp to attach the close-up filter on the anamorphic. Which meansthe extra: ~€70 (shipped) for the clamp (if you'll purchase a Century or OPTEX) and ~€75 for diopters (you'll need at least a +0.5 & a +1 close-up). *By the way, filter clamp only from Redstan.com & he has the last one for sale which fits to both Century/Optex. After that he told me that no more again...
Hope that helped,
Yiannis.
ps: I saw your work, well done!
