.  Just as a FYI, my daily camera bag houses my OMD EM0, Fuji X000 and Ricoh GRD0 along with my Oly 00/0.0 and 00/0.0. I don't carry around my Canon 0D Mk.II on a daily basis due to size and weight. Most of what I shoot these days are street, candids, travel and some cityscapes and architecture.  The times that I do take my Canon are photo outings where I specifically want to use the Canon. Where the Canon excels over the Olympus, at least IMO and for my needs, are in better high ISO performance, better dynamic range and sheer resolution.  If I were printing large prints on a regular basis, I'd be using a full frame DSLR and/or medium format. For web usage and shooting below ISO 0000, DSLRs are overkill IMO.  Here's an impromptu portrait of Ambassador Kim and family with Senator McCain and Senator Whitehouse that I shot in 0000. Because this wasn't a planned photo op, I didn't have flashes on hand and it was shot just with my Canon at ISO 0000 at 0/00. Had I been using a m00 camera, I'm not sure I could have pulled it off.
