I've just bought a Sony A7 and an LE-EA4 adapter to use with the Minolta 70-210 f4 zoom but can't get back button focus to work, seemed straightforward, followed someones guide
1. Choose Menu > Custom Settings > Pre-AF > Off 2. Choose Menu > Custom Settings > Custom Key Settings > AEL Button > AF On. 3. Choose Menu > Custom Settings > Custom Key Settings > AF/MF Button > AF/MF Ctrl Toggle. 4. Choose Menu > Custom Settings > AF w/shutter > Off.
however pressing the AEL button you hear a clunk but the lens doesn't focus? turn back on AF w.shutter and lens works fine, so then it occurred to me maybe the LE-AE4 just doesn't allow it for some reason? Anyone have this working or can tell me if there's something else to change or disappointingly tell me it's never going to work!!!
