HI , i just got a set of lomo round front anamorphics on a sub rental basis, and was primarily using it in the digital world. I have been acquiring 2 perf cameras using spherical lomo lens for the wide screen look. I had bought a movie cam compact to convert to 2 perf but the cost was too much. So i was going to sell the body, when this chance to get these anamorphic lens came about. Its a four perf version, and i am in the same boat, i don't know much about anamorphic stuff i need to make it work. SO i assume that there was a switch for the viewfinder, but i didn't see one like the ones they have on panavison, Most of my AC friends are retired, and new digital ac have no clue. So what do i need to make it work, an anamorphic ground glass, Gate, viewfinder?
