My daughter called me up today. She went by the local camera store, who we have dealt with for years and have been very knowledgeable. She's seen the images I'm been showing her from the A7/A7r cameras, and it has her rethinking her Canon 5dMkII. She's very petite, and has always had trouble holding a camera steady. Her hands used to shake a lot, and after lots of tests, she was put on a DOPA regimen which appears to have stopped the shakes, but the Canon is still heavy for her. So she's thinking about the A7/A7r, and maybe using her Canon glass for now until more FF lenses are available. This is where the fun begins. The guy at the store said that using an adapter on EF lenses may end up damaging the focusing motor on the EF lenses, and they might not AF at some point, even on her Canon body. Now I have never heard such a thing, and if it were true, it would be all over various forums. Sounded almost like pure FUD to me, and was surprised it came from the camera store. Has anyone heard such a tale?
