Originally posted by Wheatfield I've never met a macro lens that wasn't a very good lens.
As Wheatfield says...... I have the A 50mm. It is beautiful. A setting very convenient. Only lacks 1:1, which is pretty silly at this focal length anyway , which can be remedied which an extension tube or close up filter if required, and AF which is not needed for close up work but may be useful for more general photography. Personally though I prefer my K 50mm f4, for its' superior build quality and its' je ne sais quois in terms of IQ. Unless you need f2.8, I would not discount either the K or M f4 model especially if you already have a fast 50mm.
