I'm a soon to be former Pentax K-5 shooter intending to become a Rich shooter after Photokina 2012. Yes, the K-5 is a great DSLR but it's size, weight (body and FA primes), etc., is all "getting in the way" of the more traditional, less complicated, purer, if you will, experience that I'm looking. I like to shoot manual most of the time except when subject matter is better suited to aperture priority or shutter priority. I've been reading quite a bit about the GRD IV and GXR (28mm module). One of the great aspects of photography is actually shooting (lol!), what I mean is that most of the time I would leave my K-5 at home because it's just too much to carry everywhere and therefore I spend much less time shooting than I could if I had a more readily portable kit. What I'm looking for is advice from users of the GRD IV and GXR (28mm module)....which to choose and why? Pros and cons of each? I'm not looking to shoot portraits, rather I'm looking for something close to the elusive "all around - walk around" camera that I can always have with me with great IQ. From what I read, both of these Ricoh cameras have that, thought the GXR is a bit larger. I'd likely want the flexibility of an OVF or EVF on the hotshoe. Thanks!
