Rated 4.4 out of 5 by 5
Rated 5 out of 5 by SharpShooter Works great with older "A" mount lenses!
One of the main factors in my decision to purchase the A7r was due to this adapter. I had started with a Minolta film camera and moved to the a900. While I don't have a huge fortune in glass, I didn't really want to reinvest. I have listed the lenses I have below which all work well with this adapter.
Older Minolta lenses:
28-100 AF 3.5-5.6
100-210 AF 4.5-5.6
70-300 AF 4.5-5.6
17-35 AF 2.8-4
Sony alpha A mount lenses:
500mm reflex f8 (Sony mirror lens)
50mm prime 1.4
135mm prime 1.8
The two primes and the 17-35 are my favorite lenses and they don't disappoint me on the A7r. The 135mm is one heavy piece of glass but is razor sharp and color is tack on. I would definitely suggest using the tripod mount on the adapter for heavier lenses.
I do have one lens which does not work with this adapter. It is the first lens on my first Minolta. It is a 35-80 "power zoom", an odd little lens with a powered ring for zooming and focusing. Not a big loss for me, but I thought I would mention it.
If you have lenses from Minolta or Sony A mounts, I would definitely get this adapter!

Rated 4 out of 5 by Apocryphon Extremely useful, but extremely improvable
I'm giving this a 4 because 3.5 is not available and it is good enough to where I'll round up instead of down.
This said, I almost never take it off any more, though it does happen here and there.
Simply put, the upside is that it greatly expands your range of excellent glass to include Sony A mount and Minolta Maxxum lenses.
The downside is that it does not seem to effectively communicate with your camera to the fullest extent - and this is a huge downside and disappointment. I almost never use autofocus anymore, BUT, for those who do you'll find your autofocus points greatly diminished to a crosshair type pattern that you'll be familiar with from older dSLRs (I use the a6000.) This would be fine IF it was a selectable option inside the camera (especially if it allowed for more resources and speed to be allotted to those few points), but, really, and for future reference for Sony, it should communicate with the camera and have NO hindering effects on the performance of the camera in that respect.
While I seem to get great images out of it, I'm not sure if that has to do with the addition of the mirror, the lenses, or both.... I think anyone who is familiar with the CSCs that it will be attached to will find certain elements diminished (I also think it views a bit darker than e-mount lenses.)
All in all, it is a great purchase that has allowed me the use of some excellent lenses. I would certainly like to see improvements on the idea in the future.

Rated 5 out of 5 by dtopp Allows me to use other lenses
This adapter allows me to use my collection of Minolta lenses. I have to adjust aperture and exposure times, but the adapter is saving me the cost of buying lenses.

Rated 5 out of 5 by games252 it was exactly what I wanted
I have multiple lenses for my dslr but wanted the ability to use them with my new Sony. I can easily switch cameras , set up cameras for multiple use, and easy to carry. I am extremely happy with this attachment.

Rated 3 out of 5 by Pattig A to e mount adapter
I used my Alpha lens and had some problems with it connecting to the camera. Needless to say I was Not impressed.
