I bought this a few weeks ago and it has been super nice to use my old Minolta/Sony A mount lenses with my a6700. I will say there is some chromatic aberration for some of the focal lengths but it's nothing too terrible that makes me not want to stop taking photos. I've really enjoyed using this adapter!
This works very well with my all my A lens including my Sony 2.8/300 SSM. I was pleasantly surprised it also worked with my Kenko Mx-AF 2x Teleplus MC4. (With most A lens.) Unfortunately it does not work on auto focus for the Sony SAL14TC nor does it work for the Sony SAL20TC.
Just upgraded my camera to a Sony Alpha 7iv and I wanted to use my other lenses. I bought this in hopes it worked with the auto focus. It worked great, so now i have twice as many lenses to use.
This adapter did not work for what I need it for. It does attach well to camera and my A lens did attach well to the adapter, but it did not work with my sony A mount wide angle lens. Photo was darker and not as sharp as they normally are when lens is attached to my A77mrk camera. It does work, but not for what I need.
No, I would not recommend this to a friend.

Sony's commitment to customer satisfaction is our top priority. This adapter is meant for Full Frame 35mm Lenses. The A77 is a crop sensor camera, so any lenses designed for a smaller sensor will have a dark mechanical vignette around the edges. You would need to put your camera in APS-C mode to get rid of the vignette.
It's great that Sony released an adapter that can provide mirrorless AF for screw drive lenses. It's disappointing, though, that this new adapter still includes so many restrictions that applied to previous LA-EA adapters, and even introduces new ones.
Third party adapters from Sigma and Metabones can provide hybrid AF and fast CDAF, and support such behaviors as stopped-down AF and use of the AF illuminator, but Sony still can't do these things for its own lenses on its own bodies with its own adapter. Further, screw drive support for AF is limited to just a few newest and highest end bodies. All of this sounds like firmware, rather than hardware, limitations, since other third parties, like TechArt and Monster have adapters which provide screw drive support on older Sony bodies. I hardly ever shoot video, but the LA-EA5 providing less support for video than the LA-EA4 is also disappointing.
In good light, though, for stills shooting, the LA-EA5 on the A7R4 is quite good. Fast and flexible AF with few limitations. Being able to use all the OSPDAF points with my Minolta 24-105D lens is great. In lower light, though, AF from the LA-EA5 struggles. Even in daylight indoors, trying something like the Sony 18-250 is much slower and less likely to get a lock than on the 10 year old A390.
In short, if you have a newer Sony E mount body, and some A mount lenses you would like to continue using, the LA-EA5 is your best choice, but there are still things Sony could probably do with firmware that would make it a true upgrade from A mount bodies.
It rocks, given a proper system setup. The sample pictures were taken by A7r mark iv + Sony 70-400 SSM G (ver 1). The AF tracking ability is surprisingly good. It doesn't feel like an adapted lens at all. In some cases, it may perform better than my trusty a99 mark2. However, for non-SSM lens, the tiny motor inside the adapter struggles a little to drive heavier lens, like the Carl Zeiss 135mm f/1.8. All-n-all, this adapter is a must have for any serious A-mount user.
While I am fortunate enough to have the proper body to fully utilize its potentials, Sony, please expand the supported body list. Other users complaints are absolutely legit. If you want your customers to be loyal to Sony system, Sony must provide a wider range of backward compatibility support. For that, I take down my rating a touch, to 4-star.
