Will this adaptor allow me to use lenses that mount on a Zeiss Ikon Contarex on a Canon EOS?
it did not work for me putting Optar Primes to a Canon C300 - total waste of time and it messed up my shooting schedule
test if you have time, return if it doesn't work
This adapter, while great in it's intent, is short on the list of lenses that it works with. I bought it to convert cinema style lenses to my Canon C300 and found that after buying it, it did not take most of the intended lenses from Optimo, Angenieux, etc. that I was interested in adapting..
so, check it out carefully, or just buy it to try it..you might save the receipt.
