I have been looking over options to upgrade my existing MFT kit (which consists of a Panasonic GF1, 7-14mm f/4, and 20mm f/1.7). Originally, I was going to move to a GX1 and add the 45mm f/2.8 to the existing lens kit. Then I got looking at the Olympus E-P3 with the new 12mm f/2 and 45mm f/1.8. I've compared the sensor output (JPG, RAW, high and low ISO) on DPReview, weighed out the plusses and minuses, and even considered mixing it up (i.e. GX1 with some Olympus glass). I've gotten great output from my GF1 kit, and if I shoot RAW it appears that the GX1 has the edge over the E-P3 (although comparing the GF1 and E-P3 in RAW at ISO 1600, the E-P3 looked slightly better to me). But here's the thing - I thing this has gone beyond the analysis (it's obvious that both cameras and potential optical kits are capable of great results)... it has turned emotional. I absolutely love the look of the E-P3 in silver with the 12mm f/2 or 45mm f/1.8 on the front (like this one: Olympus E-P3 12mm f/2 | Flickr - Photo Sharing! ). I find it classically striking. The Olympus kit still has technical reasons to draw me in (like low-light street photography at 12mm with a two-full-stop advantage - without IBIS - over my 7-14mm). I can't believe it seems to have come down to this - the aesthetics of the camera itself. Anyway, I don't think I've left any stones unturned in my technical comparison, but if anyone has something you think I might not have considered - or if you just want to reinforce my emotional response - feel free to share.
