[QUOTE="mikew_RIP, post: 562018, member: 14174"] I had the Nikon 200mm macro with IF on my 35mm gear,yes it was very sweet to use as we only had MF in those days,i now have the Sigma 105 and do find it can block light at full ext,but what i dont know is if IF keeps the front element further away from the subject at a given magnification,ie is the IF any longer in the first place.
