Originally posted by RobA_Oz I have both the DA35/2.8 Macro and the FA31/1.8 Limited, and they're both lovely in their own, if somewhat overlapping ways.
I can see a purpose to this, if only in that the FA31 is ever so slightly wider, a stop and a bit faster, and (from what I've read) a shade ahead in quality, plus it has effortless retrofit compatibility with film bodies (if that's what you're into) and the FF DSLR when it eventually comes out. That's when the 31 becomes a 31 again, rather than (approximately) a 45.

No, it probably wouldn't. I actually originally bought the 100mm WR f/2.8 Macro, but found I needed a much wider field of view for the larger specimens. I thought very hard about the fifty, but decided that it was better to go to the other extreme immediately than to go middle-of-the-road and have regrets. Experience has shown me that I did the right thing. It was an expensive mistake, but I can't bring myself to ditch the hundred - if nothing else, I have a fairly fast short telephoto lens that's good for portraiture, with backup macro capability if I should ever need it. This is good because one of my dogs is very photogenic, but only when it's resting - and that isn't when it's outdoors or I'm shoving a wide-angle lens in its fuzzy canine face.
