I came across on this (see below) for sale here in raleigh going for $40 and I've looked through here/google and noted that if these have the little pin on the mounting ring then its best to remove it so that it wont jam on the camera... so that is good to know! But I'm trying to find out if its actually a good lens in terms of quality and if anyone else has used this. It says its a macro but then says min focusing distance of 18"? I always thought macros focus much closer... Any input/advice would be appreciated... Thanks! For sale here is a Sears 80mm-200mm f:4.0, macro/one-touch zoom lens, in original box. Serial Number is 850815655 It has multi-coated surface to reduce flare, a macro ring for close-ups as near as 18", and constant f:4.0 throughout the zoom. It is for the Pentax KR mount, has the A-position, ideal for Pentax DSLRs, like the K10D.
