I don't plan to buy anything for this year, but I've started collecting some information to evaluate the available options, just in case I should conclude, at the end of the year, that there's no "native" choices in the 2016 roadmap.
As I suspected, reasoning with different mounts and adapter is a mess, because of a number of factors.
Anyway: let's say I'm thinking of two distinct solutions: first a birding lens, light for carrying along in a hike, hand-holdable, to replace the Nikkor AF-S 300 f/4. Quite simple: it doesn't exist and so it's not a thing I can even start thinking about. The second solution is a longer zoom, that would be definitely heavier, so not for hikes, but to use in short walks or from the car; for landscapes also, stationary birds or wildlife, even though I'd like it to have AF fast enough at least for trying some simpler case of birds in flight.
I see four possible options:
There are weight, but especially wild price differences. I'll think of them later. First I need some technical information.
First, I don't understand whether I need the Sony LE-A1 or LE-A2 adapter for having fast AF with the A-mount lenses. Apparently the LE-A1 is enough, because those lenses have their own motor, but if I understand well it wouldn't support PDAF. Honestly, the LE-A2 would close the discussion for me, as it sounds absurd to have a mirrorless system and add an adapter with a sort of mirror inside.
Second, if I understand well, the Tamron in A-mount doesn't have stabilisation, so it would be not an option.
Third, I'd like to understand how the Metabones adapter for Canon AF performs.
All in all, I see good chances that none of the possible choices is working.

- SAL-70400G2 via Sony A-E mount adapter;
- Canon EF 100-400/4.5-5.6L IS USM II via Metabones adapter;
- Tamron SP AF 150-600mm F/5-6.3 Di VC USD via either Sony A-E or Metabones adapter in Canon mount;
- Sigma 150-600 mm f/5-6.3 DG OS HSM Contemporary in Canon mount via Metabones adapter.
