Upload & Sell: Off
Hello! I've been photographing for 50 (fifty) years and used predominately SLRs w/film. Two years ago, I bought an Olympus E-P3, their 35mm lens, the small flash and their 90 degree, hot shoe mounted view finder (which, by the way, Leica uses EXACTLY but w/their nomenclature). Really, really nice outfit & pics.
That being said, I have sold it and saved-up enough $$$ to buy a Canon 5D MarkIII and a 50mm F/1.8 lens (not type II). Why? I truly missed the feel of a SLR and now that it has a FF sensor, it has the capability of producing some great photographs. (Prior to this, I would not have spent this large sum of $$$ on a DSLR, as I have felt that their capability to produce close approximations to the film/slides that I used was lacking. Sure, I could have gone to a MFD or spent even more $$$$$$$$$, but just felt that that was NOT the way to go.
So, my thoughts are: keep your Canon gear, or perhaps sell some of it to finance a G15, a Ricoh GRD IV, or even a Canon S110, etc. I STILL use my FujiFilm F30-a much desired 6MP compact camera. That has traveled w/me to Machu Pichu, Death Valley, to the top of Mt. Taylor, etc., and have gotten some wonderful shots. Shure, there is no RAW, but once again, it is light & very portable.
Good luck: take your time and evaluate, evaluate, evaluate what you REALLY LIKE to do in photography. THAT will be your ultimate guide. BTW, try traveling light w/your 5D II: just take along either a 50mm or even better a 35mm and work on informal, street shooting. Just use your feet :*) !
