I really can't make up my mind whether I want this or not. Full frame does appeal to the gearhead in me, but when I look through my favourite photo's - are there that many where I think "I wish Id had a full frame for that shot?"
Not really, my K5 is a cracking camera, my lens collection covers most of my needs, and when I upgrade to the K3 or whatever, Im sure it will be more camera than I have ability for and can grow into.
Maybe Im so used to ASPC that I have forgotten what Im missing.
