Bob, I know my A77 in and out and have used it under just about every photographic condition imaginable in the 3 years I've had it. All this is to say that I've EXTREMELY familiar with it's capabilities and operation.

The A77II is a MUCH better camera. It does focus faster... exponentially faster, and the focusing system is as good as any other on the market save the ones on the D4S and 1DX. Additionally, the flexibility is amazing. There are SO many things you can do with the AF system that you can't do with the A77.

Low light photography is also improved. The AF system is much more sensitive now using the pop-up lamp. (The only draw back is when photographing people you have to WARN them that the first flash is NOT the picture being taken! :lol: )

Additionally, there is LESS noise, and my favorite low light feature, Multiframe Noise Reduction, has also been improved.

I dislike the loss of the GPS module, and even though I personally don't use NFC I can see how it would come in handy, ESPECIALLY for remote control with a smartphone or tablet. The WiFi module can also be useful, though I don't use it either.

I also like the ability to customize the menu... a feature popular with NEX cameras. It's REALLY nice to be able to lay out the display EXACTLY the way you want it.

I'm still experimenting, and truth be told, you could spend a year learning the in's and out's of this camera before you master it.

I thought the A77 was powerful. Well, the A77II makes it look like a beginners camera!

I LOVE it!
