I'm doing some research to figure out what camera to buy. For financial reasons I'm considering the a6000 or a7. I own a few Sony and Minolta A mount lenses which I know will work with adapters. I also own a couple of Canon L lenses with IS. Will the IS function with either body? If not, which one do you recommend? I need IS or SS because I have muscular dystrophy and it's a big aid in keeping the camera steady.
