I'm going on a little vacation in two weeks. Might see a little bit of wildlife. Not that I want to be doing professional wildlife photography with the kinds of zoom lenses that entails, but I'd like something with much narrower field of view than my 23mm Summicron-T.
Should I rent the Summarit-M 90mm or the APO-Vario-Elmar-T 55-135mm as a secondary lens? Anyone have experience using both?
I tried the 55-135mm a few months ago and autofocus was so slow it was almost unusable (so might as well get the more compact manual focus M lens). But I haven't tried it with firmware 1.4.
