I'm considering buying the E-P3 and saw that the kit with 17mm is being sold for $100 less on eBay from a reputable dealer. I already have the Panasonic 14-42 (or is it the 14-45.....it's the one with the plastic mount). And in general, I prefer primes. But I was planning on getting the kit zoom since I also have the Panasonic 20mm that I love, so felt the Oly 17mm was redundant. But this small savings has my considering getting the 17mm. So the question is does anyone have any experience to compare the new Oly kit zoom vs the Panasonic kit zoom? I assume resolution should be about a wash, but was most interested in the speed factor since that it one of the biggest selling points of the E-P3. Is it noticeable? Is it worth the extra $100?
