Even though I'm trapped in my house, at some point hopefully the plague will be over and I'm thinking I need a new 90mm lens. Right now the only one I have is the 90/4 chrome elmar (from the time of the M2 and M3). It's actually not awful, but I would like something better. I am sensitive to weight (so the OLD summicron 90 is out, it's just too heavy). But I could probably carry the new 90/2 or even the APO (they seem to be about the same weight) and then there is the 90/4 macro elmar as well. And then there are the Summarits which are much cheaper and also light. And the old standard 90/2.8 Elmarit M. I saw one of the dealers I've bought form before had a 90/2 pre-APO which seemed to be going for a decent price. Would I like that lens, do you think. Both my other main lenses are summicrons so I'd have the set. Any opinions? Thanks!
