Of course you can switch the A-Mount lens to manual (switch on the lens), then it will allow M mode and any aperture other than f3.5, but that's really not the point of using this product with an AF lens. I can not refocus manually while making a smooth slider shot or using a flycam stabilizer.
I know the three star review will potentially upset shoppers who only intend to use it for photography, but as a product I consider it a fail because of the above limitations. Quite a few people resort to Sony for video. So, be warned.
So you know I'm not a Sony fanbois (strictly speaking), I'll start with the cons:
It works, but it's NOISY (and this is coming from a guy who doesn't mind the a7R shutter), and although it adds Phase Detection, in anything less than good light, it's slow. (Sorry, Sony - but I have 30 years invested in this gear, and it's just not quick or precise). NOWHERE near the AF speed (or accuracy) of the same lens on the A77 or 99 (and with the FEZ551.8 it's very capable, *amazing, actually, with EyeFocus* so it isn't the body).
The screw drive lenses (28-85/3.5, 70-210/4, 16-50/2.8, 17-70/2.8, 50/1.4, 50/1.7, 90/2.8, 105/2.8, 135/2.8, 10-20/4.5) all have varying degrees of mechanical NOISE - I mean like very clear clicking and muted banging/slamming of gears. as if there's slack space between the drive pinion and the corresponding connector in the lens. It actually scared me a little - it sounds like something may break - seriously. It's the worst in marginal light when the system has to hunt a little - it clicks and clunks like anti-lock brakes in a panic stop on a snowy road, and vibrates like that too.
In daylight, it's quick and reasonably precise, assuming you pick a good spot to focus on. If you accidentally spot focus on a shadow, however, it often sends the macro capable lenses (105/2.8 especially) into a fuzzy seeking loop that will cost you shots - I personally guarantee it. I've taken to just hitting the MF button, rack in by hand close to where it should be and then re-engage it; otherwise it hunts itself to a stall, and the a7R battery just isn't up to that task too often if you're working.
And yes, it sucks the battery down faster, but that should be obvious to anyone mounting a mechanically focused lens on an electronically focusing body. I always have 3 spare batteries in pockets or straps, so I don't mind, but you might.
The last con is the EXTREMELY delicate STL membrane on the rear side. It can not be cleaned outside of a technical facility, and I got one first from warehouse deals that someone had tried to clean themselves (apparently with a chainsaw and a hammer) that would NOT produce a sharp image. The film is fine as frog hair, so even canned air could be devastating. The front opening is less sensitive, but still - be careful. I would never - never - never expose the rear port (camera side) outside in ANY wind or even inside if there was any possibility of dust attaching itself to that surface.
Now the pros:
It fits. Right, tight and solid. It has a screw socket for mounting on a tripod (but not on a larger than small quick plate). It's light, it doesn't take up much bag room, works on HUNDREDS of lenses, and for the right person, is a source of great options and creative latitude.
Nobody now makes lenses with the color of the 70's-90's Minolta glass. When all the old Minolta glass is gone, it will be a sad, sad day for me, personally, because I absolutely LOVE the feel of many of those old lenses. Newer glass is technically sharper in many cases, and Zeiss has it's unbelievably 3D 'pop', but for rich, mesmerizing saturation and rendition of color, nothing made today matches the old Minoltas. To be able to put the 'beer cans', which I have lovingly guarded for decades, on a 36mp sensor with no AA is borderline sinfully delightful.
You haven't seen the best images those old lenses can produce, and you haven't seen the colors possible from the new full frame E mounts until you strap the two together on a sunny day with some fluffy shade makers floating around. Add a CPL and the images, literally, have otherworldly potential if you know what you're doing. With the camera set to all flat response, the depth and vibrance of reds and greens are impossible to duplicate any other way outside of some deftly built PS layers. In fact, if you want the images to LOOK believable, you may have to reduce vibrance and saturation in post; in many situations, the files OOC look over-shopped and "too" color-rich. Get your white balance set wrong, and it's off to crazy town if there are people in the shot. They really are THAT saturated and vibrant; if it's wrong, you're not getting it out in post.
But back to the adapter (I apologize). IF you already have a bag or two full of older lenses, it's a must-have, and gobs of fun / nostalgic magic wand. If you don't, or only have a couple, keep your old body and your money (and wait). The a7/a7R is a great enough platform that eventually, there will be FANTASTIC glass, and once the 3rd parties start building for it, it's REALLY going to take off, not to mention the fact that it will knock Sony's giraffe-knob prices down a peg or two.
Cautiously recommend for certain shooters, but due to the mechanical scariness, highly recommend extended service for it as well; it just doesn't appear to be robust enough to do it's job indefinitely.
The natural progression then was to use them on my Sony A6500. This adapter is exactly what I needed to do that.
It has a screw-drive so that it can auto focus the Minolta lenses. As I understand it, the LA-EA3 does not.
I tested this out with my Minolta AF 85mm lens and compared it to my Sony 85mm lens. There is certainly more hunting (attempting to acquire focus) using the Minolta lens and there are less autofocus points when using this adapter and adapted lenses. Other than those minor issues, which are to be expected I suppose, this adapter is a great addition to my camera. It allows me to use a lot of old, inexpensive lenses to take great photos.
I am happy I picked this up.
It has it's own auto-focus motor, which ends up stealing just a teeny bit of light, so an f-stop of 2.8 becomes 3.x. Meh, not a big deal.
The auto-focus is contrast detection based (identical to the first generation A99 auto-focus).
It's fine. A little slow by today's standard. Though since I use it for the A7SII, which has an auto-focus that goes down to EV-4, it's a bummer that this focus can only do EV-0 or -1.
If you already have A-Mount lenses and now have an E-Mount camera (like the Alpha series), this is pretty decent.
But, if you use an A7RII, or likely the upcoming A9 series cameras, I'm told that the LA-EA4 allows pass-through auto-focus, so you can actually use the phase detection auto-focus (which is much faster) of the actual camera, instead of relying on the auto-focus of the adapter. Since I use the A7SII, that pass-through option isn't available, forcing me to use the auto-focus of the adapter, relegating me to the LA-EA4 as the only option.
However, if looking for a new lens, and thinking the LA-EA4 is a good option to get a new A-Mount lens onto an A7 or A9 or A6xxx, I wouldn't recommend it. At $400 (heck, even at $150), the price add-on isn't worth it. Better just to get an FE lens (FE = E-mount lens that is Full-Frame compatible, vs. an E lens, which is an APS-C E-mount lens).

The adapter is hit-and-miss with other brands such as Sigma or Tamron.
One will need to do some research before using other brands.
