larry i'm going om-d, but i am always curious at the philosophy of putting huge slr lenses on mirrorless cams. it always seemed to me CEVIL cams have 2 'advantages': theyre small, unobtrusive & thus nonthreatening, and you can mount most any lens ever made to very nice effect. but the negatives are crop factors of 1.5 to 2x. imo, when i wanted to mount huge lenses, i had a FF 5d. i left that cam/lens combo--and with it the advantages of shooting great lenses FF--for a compact CEVIL rig, then to be coupled with similarly compact lenses, in my case RF and kodak retina dkl. i am always confused about why one would choose CEVIL and then destroy its primary advantage? if one loves BIG lenses, why not pair them with a BIG FF cam?
