I'm getting an M. Mostly this will be my Parks (WDW) travel setup where the 5D3 is too bulky/heavy.The "M" is APS C, so you will see a angle of view 1.6 X that of a 200mm lens, or 320mm.
I'm thinking for Animal Kingdom in bringing the M with the Tamron 70-200 + 1.4 TC. I get 448mm @ f/4. Is that right?
Have you tried one with the Tamron? I would not expect it to work well with a Tamron lens, it may be extremely slow to focus. Most third party lenses do not play well with Canon's live view. There is no phase detect with a EOS M, so try first or make sure you can return it.
With a huge lens, the body size makes only a slight difference, and balance may be poor. You might be far better off with a SL1 and the ability to use phase detect AF if you want a small body. Tamron Af will work reasonably well with phase detect.
SX50'HS is a nice, small, almost pocketable, cheap super telephoto, but if you want better IQ, then you should avoid TC's on zoom lenses as well. Otherwise, you won't get a much better result than a super-zoom P&S camera.
