The title suggests that I'm going back many years when I say old, but this camera only come out a few years ago. Of course it's obsolete within 18 months as technology advances at a fast pace. I also have the E-420 which was the model before the E-620 came out. Of the two I prefer the images from the E-420. So why also purchase the E-620? Easy, it has IBIS and the E-420 doesn't.
Going back to a post some days ago when I mentioned that people love to surround themselves with new equipment, both of the above mentioned cameras can make better images than I can make. I decide how the image is taken and with what settings, not the camera. Probably the E-420 would be enough for me but it's that new equipment addiction that pokes it's head out from time to time.
