A65 is consumer level construction ie not magnesium alloy. Second the AF system is lifted from the A55 not a new system like the A77. No top LCD either. The backscreen only double hinged. More important can only do 10fps and max shutter is 1/4000. No X socket as well for flash. But the body is abit smaller which might please some. There are fewer buttons on the rear. There is question over if the ISO is capped at 1600.
