Greetings everyone. So, I'm planning to shoot a narrative next month and I will have canon 5D Mark III and 1DX. I have a set of old canon fd primes from 24mm-100mm and two zooms brand new 35-105mm (I ordered from eBay) and 80-200mm. I was planning to use them on the shoot and I got some questions. What is the best adapter that will work? Will lenses vignette? Is there anything specific I should know before using them on eos bodies? Stuff like that. Thank you.
