I'm looking into purchasing a set of lomo primes in oct-18 mount. I noticed that to directly mount the lens to a canon camera you have to buy either a oct-18 to oct-19 adaptor, and then an oct-19 to EF. They also make oct-18 to pl, and then pl to EF. Anyways, with either of these adaptor setups, I noticed that the oct-18 versions of the lomo anamorphic primes rear lens barrel rotates when focusing. Does anyone have any insight or experience using or converting oct-18 lomo anamorphic primes to any kind of canon EF setup???? And if so how does the focus work, or ways around it??? Any help is greatly appreciated!!
