It depends....I love my A77.
Pluses are the SLT technology means the EVF shows you how the photo will look unlike an OVF. If the EVF is too dark then your photo will be too and vice versa.
It's fast...very fast. In fact the 10fps is useless. But it does mean if you put it in continuous high/low it's still faster than most Nikon/Canon's.
All Sony's have IBIS so that's a plus.
Downsides......
Erm battery life. You can take around 300 shots max. For a full day wedding I can use 3 batteries. I can get through a day with a single battery on my Nikon. Not a biggie. Batteries are cheap.
ISO performance. It's not great after 1600.
But when all said & done, unless you can get a substantial discount then the D7000 is significantly cheaper for virtually the same features. And if you want to stay Sony then look at the A65 which again is much cheaper and all you lose is the weather sealing, some buttons and the top LCD (which I never use cos all the info is in the EVF).
