Moving to FF, and also moving away from SLT pellicle mirror will offset the loss of IS. The adapter however re-introduces SLT as part of the A mount adapter solution.

A problem I find with the later SLTs is it is hard to know what benefit IBIS is actually providing in real terms. I do not see a great difference when it is on or off in most shooting scenarios.

At least some of the later SLTs (e.g. A77) have two different kinds of IBIS, one for stills and one for video. You have to be sure you're turning the right one on & off. Of course you won't notice any difference except in shots which were slow enough in shutter speed to have been spoiled by a bit of camera shake, but not so much that the IBIS can't cope with it. I seem to be steady enough that If I shoot in auto modes the auto tends to keep my shutter speeds high enough that IBIS isn't needed, i.e. it has no effect. But when I deliberately push shutter speeds lower into the danger zone i find it is very effective.

HI Chris

I certainly agree, most of my shooting is daytime shooting in good light so IBIS is not really required or noticeable, particularly for portrait shooting. It all depends on shooting style, lighting, and subject. IBIS does help when the camera is limited with higher ISO so the A77 benefits from it under low light conditions. I think FF, no pellicle with native lenses will definitely offset IBIS to a large degree considering the better ISO performance expected.
