Almost the same size. That's really good news though, because A77 I and II have a really nice and easy-to-handel size, with a good grip and many control bottoms .
I bet Sony engineers have learned a lot about squeezing stuff into small cameras when they worked with those tiny E-mount bodies.
Yup on all that. I love the size and feel of the A77ii. Part of why I was willing, sight unseen, and pictures unprocessed, to lay down the large sum of $ for the A99ii. Will not be dining out much in the coming year though :-D .
