I have one of the cheap IR Remotes for my Sony cams. It (sort of) works on both the NEX and the A7r. I have the A7r set so the AF is not actuated by the shutter (only by the AF button on the back - that is the way I used my Nikons for tripod shooting for years). Last night when I set up on the tripod and used the IR remote, it appearred to try to re-focus the camera. Does anybody know anything about this behavior and whether there is a setting I may be missing?
