I have a few 24 and 28 lenses that I have been using. I find that 24/28 is a particularly nice match with an APS-C sensor camera as you get 36/42 EFL. I have a few favorite 24/28 lenses like the Rokkor 24/2.8, Hexanon 24/2.8 and Vivitar 28/2 but my recent experience with the Konica 40 has made me really appreciate a really compact lens on the XE1. Any suggestions? Right now I'm leaning toward a Super Takumar 28/3.8 or perhaps an Olympus 28/3.5 but I'm open to suggestions.
