I have a conundrum. I currently shoot with a Nikon D300 and D5100. The D300 tends to get used around the house (family, flower macros, pets etc), and for weddings (1 or 2 a year). The D5100 tends to be the walkabout camera with a 18-200mm on the front. I enjoy architecture and candid people photography, but find the live view of the D5100 painfully slow. The movie mode is also not the best (lousy auto-focusing). After the recent and unexpected death of a much loved pet, I realised that I had too few films of him and those I had were of less than excellent quality. Thanks to a back problem coupled with bouts of medication induced fatigue even the D5100 and 18-200 can be a bit much to carry around. Therefore, I'm looking at a 'killing two birds with one stone' solution - better video capability plus a lighter walkabout (including candids using live view fold out screen) camera. I used to have a G1 but sold it due to the badly positioned command wheel and no movie mode. However, having just done some RAW conversions in DxO 8, I'm very pleasantly surprised at the overall image quality - much better than I remember from using camera raw. I'd be looking at a 14-45 (or 14-42) plus 45-200 (or 45-150) setup - total weight about the same as my D300 body or around 250-300g lighter than my D5100 + 18-200mm. The question is, do I go for a used/refurb GH2 or new/refurb G3. I'd guesstimate around 90% min. use for stills & 10% max. for video overall. Decent high ISO is desirable but not essential. Decent dynamic range is more desirable - especially good shadow detail when trying to tame highlights. Suggestions and recommendations gratefully received.
