looks like the improved version with TTL and phase detection AF support is $50 off as well.

It's not so much that the laea4 is the improved version - they serve different functions.

The laea3 uses the camera's own autofocus system (though sometimes with not all features enabled), though only with lenses that have their own motors (as most modern lenses do). With older cameras, that just meant unbearably slow contrast AF. Starting with the a7rii and a firmware update to the a7ii, it could use the on-sensor phase detect AF for performance that was much closer to native. Some advanced/smart functions were still disabled, but the most recent cameras and firmwares enabled more, including eye af.

The laea4 uses its own AF system with a translucent mirror, much like a Sony DSLT. That sacrifices about a third of a stop light transmission, uses a cluster of AF points close to the center, is subject to calibration issues and can't use the smart AF functions. But it's also the only option for using lenses without motors (the "screw drive" lenses). It's also the only way to get video AF with an A mount lens on an adapter, though the aperture is locked to f/3.5 (or the closest the lens can get).

So for most modern lenses on one of the newer bodies, the LAEA3 is better. For a screw-drive lens or one of the earlier bodies, the LAEA4 is usually better.

Stop using mine and eventually sold it because it was excruciatingly slow.

I have 3 lenses from a Minolta Maxxum 7000. To save some money, I would like to mate them to either an A mount body like the A99 or an E mount body like the A7ii with an adapter like this. Primary use is video. Any thoughts?
