Well, I just this weekend done exactly what your thinking,
I was shooting sports team photos and a few action shots for pay( not full time, weekend stuff)
and travel,family,fun,landscapes other times.
in both cases I found "customer" arround the sports soccer fields seemed to like the way you looked with a dslr,grip and big white lense, as with weddings,etc, the " look" seems important to look pro. But carrying the very heavy bag,camera,and lensemay look good,but its so cumbersome and heavy, I went skiing in nz four weeks ago, took lo pro bag full. Pain in ass on airport,plane,and certainly up slopes, when to be honest, it came out once,and I missed an arvo skiing,lugging it arround
so it all got sold, this weekend on eBay, all gone, now I got $3500 au, to get my next rig,
im now researching a lightweight system, still can take a team photo in raw.with full manual, and, with a decent lense, still take a action shot, but can also easily slip into a pocket,with a small prime on it.
My choices :
olympus E-M 1.........coming any day a true pro cam, but small,good previews
E-P5..... Tested and reviewed, but a bit " pretty boy" ( or a girls camera) trouble coming from that comment
Panasonic GX7... Great reviews, slower shutter, retro look, feels good in hand, but is it " pro" enough?
or a canon G16 ( easiest to carry,but might not give me a reasonable pro look if I decide to do some team shots .
anyway , the store i was in ,teds, all had the opinion the 4/3 mirror less was a growing trend, and predicted it would be the norm very soon ( unless you work pro full time)
Just my research and thoughts, I'm not decided which yet, I wait with interest on opinions
