IBIS and the lack of it with NEX - a question

If you're going to be doing a lot of telephoto shots esp. with legacy lenses esp. in low light then yes it is a problem. It was a deal breaker for me so I got an a77. If you're going to be doing portraits the larger Sony sensor will give you shallower depth of field. That's the main reason I gave up on m4/3 which is otherwise a fine system. And most Olympus lenses are excellent.
