I have the Olympus PEN E-P1 and it's OK as a backup to my Pentax, especially considering I got it for a song. I am wondering if there is a better camera for me, since I want to use a viewfinder and this forces a new purchase. So far I have been unimpressed with the models that have come after, since they seem to be either missing key features or too expensive for me. But I could be wrong and so ask for the help of those more knowledgeable than I! I shoot mostly in Av and so need direct access to aperture, exposure compensation and ISO. That's very basic, but my E-P1 does not let me assign ISO to one of the soft buttons. I have learned to live with using the OK menu for this, but it's not ideal, since OK has other functions. It would be great to use a flash trigger and viewfinder at the same time, though I think no model manages this. So, OK, another compromise. I use legacy lenses and need quick access to the focus magnification. The E-P1 ties this in with info screen selection, which is a PITA. This bugs me a lot. IBIS is essential, since I work in available light a good amount of the time. This is why I am only considering Olympus. Reports indicate the IBIS on the E-PM1 is broken, so that one's out of the running. Any other models I should eliminate? I don't care about extraneous "features" like touch screens and don't need to have the most recent model, unless it really makes photography better. Faster burst rates and AF mean nothing to me. P.S. I am posting this on three forums out of curiosity, to see where I get the best info.
