I'm having a bit of a tough time selling myself on the panny 12-35. I generally shoot with primes, but I miss having a zoom for travel. I've been considering the 12-35, but at approximately half the price I'm starting to think that the RX-100 might make more sense. The RX-100 obviously wins on price and pocketability, but do you think I'd see a noticeable difference in image quality between the RX-100 and the OMD with the panny 12-35? Any OMD owners using the RX-100 as a second camera? Thanks.
