The new AFD version has an update in multicoating and adds cfc (close focus correction), reaching a minimum focusing distance of 0.25m. It adds screwdriver-type AF, and all the distance info for 3D matrix and TTL flash use
Filters are 4, rear bayonet-type: L37C, on the lens, O56, A2, B2 inside a blister included in the package, and named CA-2. The blister is in a kind of faux leather that degrades in time and for unknown environmental reasons.
NEVER BUY A 16MM 2.8, IN THE AI, AI-S, OR AFD VERSION IF IT HAS NOT THE L37C FILTER ON THE REAR LENS. It will affect field curvature and focus capabilities because it is PART OF THE OPTICAL DESIGN.
