I notice a a number of the "this brand or that brand" types of question son the forum from time to time and I figured I'd share my experience of owning both an E-P1 and G2. First, I don't find much difference between the two cameras in terms of IQ. If what you're after is great pictures (and assuming that you've already decided to go m43) either one wil do the job nicely. The E-P1 has it all over the G2 in terms of style and design. Its a great looking camera with just the right amount of heft. The Panasonic on the other hand has a very "form follows function" appeal which is to say that it is homely. It looks like a DSLR only small. Surprisingly the E-P1 sits home a lot because while the G2 my not be the most attractive of cameras it is hugely functional and the whole point owning a camera is making images. I have a number of manual focus lenses and while they work well on either camera the EVF on the G2 makes using them much more practical in bright light. The ideal setup (IMHO) for the E-P1 is with an AF prime on it like the Panasonic 20 or 14. The Panasonic 14 is nice because it's quite and the AF is very fast. The 20 is a better lens but it is not particularly fast to focus and that is only exacerbated by the AF on the E-P1 which in full auto mode is "interesting". Using the E-P1 in A mode and setting the metering to center weight help quite a lot but it's nowhere as nice as the G2 in the AF department. Something I was thinking would be a huge advantage in favor of the E-P1 was the fact that Olympus bodies have IBIS where the Panasonic relies on it being in the lens. Previously I had been using an E-PL1 with an attached VF2 and it worked quite well. The problem I had with the E-PL1 is that I found the control layout to be frustrating. I did not care for the point and shoot style button layout and while I did eventually get used to it I find the layout on the G2 to be much nicer and I find myself being able to maneuver the controls without thinking about it. I feel like the layout is very intuitive and that makes a difference to me when shooting. To it's credit the E-P1 has a much nice layout than the E-PL1 did but still not up to the level of the G2. As for the advantage of shooting with IBIS on legacy lenses...to be honest I haven't missed it. That is not to say that it isn't useful but I have not found myself in situations where I felt that I would have gotten the shot if I had only had IBIS. In the end, I have ended up using the G2 for most of my stuff. The times when I choose the E-P1 are when I want to take some photos but not call attention to myself. The DSLR style of the G2 screams CAMERA. the E-P1 manages to have that rangefinder vibe and I find it tends to not get noticed as easily. They are both very capable cameras and I like them for different reasons.
