The xa is nice because it is so portable but it is almost TOO small. The finder is tiny and the focus lever has about a half inch of movement. I also notice a bit of vignetting on the xa. The corners are darker than the rest of the image. And I took a lot of accidental pictures. That electronic shutter button has a hair trigger. But it sure does fit nicely in your pocket.
I actually liked the olympus rd or rc or ed or sp or whichever better. Seems to fit the hand better, but not the pocket.
