not sure how nightmarish it would be to hold a 70-200F2.8 with the sony, I would think just as bad as the DSLR, which I'm holding with two hands anyhow. For short tele and wide, sony checks a lot of boxes. There arent many lenses that are small, that collection is limited to a half dozen lenses unless you're willing to get into the vintage prime/leica territory, then your options are huge.
I think I am going with a small kit that involves some small and some large lenses.
14 - medium
28mm - small
50 - small
100 - big
28-70 - medium size but super light (maybe the upcoming 24-240)
the 28-50-100 will be my core everyday shooting lenses. The great thing about the sony setup is that the body is hardly intimidating. People will get intimidated by my 6D, not so much with the A7r. it's small, it cant be serious 

Is it the Canon-mount (ZE) version?
