Sony LA-EA 5 Adapter Review: Real Time Tracking with A-mount lenses

In this thread (https://www.dpreview.com/forums/thread/4519508#forum-post-64475460) someone just confirmed 10FPS with continuous AF with the LA-EA3 and A7III. Sony says this doesn't work, but the results are quite clear.
That was with the A7r iv and firmware 1.20, not the a7iii.
Oh. Sorry. My mistake. However Sony still says this should not work.
Well, they actually do say that it works. However the wording might be a little confusing, and maybe not all their webpages are updated. But on the Sony Japan webpages the compatibility information on the LA-EA3 adapter (and the LA-EA5) on the A7R IV with a-mount SSM lenses says:

"When you perform continuous shooting in the Hi+, Hi, or Mid mode while the focus mode is set to AF-C, the focus does not track a subject. To enable AF continuous shooting by setting continuous shooting to Hi+, Hi, or Mid mode, the system software must be upgraded to Ver. 1.20 or later and the Mount Adaptor software must be upgraded to Ver. 02 or later."

Thanks for that.

The web page I had linked in the other thread was updated October 12th 2020. It's the one that says that only Continuous Lo is supported: https://www.sony.com/electronics/support/articles/00059736
 
I would be interested in how you reached the page you are citing. And I AM interested in the fact that it makes no mention of the A6600, nor (if my eyes haven't failed me) of the LA-EA5. Having run a (much smaller) website for a couple of years, I do know how hard it is to keep all the content current, but this is weird ...

I Google something like LA-EA3 ILCE-7RM4 Continuous AF, and that's the first result that comes up.
 
Fair enough, but still ought to have been updated by now ...
 
I've was far more active on here with my Minolta film cameras and then somehow got lost when the website changed several years back and maybe was deleted or lost track of my log in. So since then I've been served well just lurking as I went from those film cameras through the Minolta Konica Digital to my current A77ii/A700. Eventually most of us will end up being forced into making decisions on what to do after the A mount. Since I prefer a crop camera and I use it pretty simply (no not in 'P', but in 'A' and Aperture Mode mostly), The A77ii for all it's fine features has been as much camera as I need and will continue to be my camera along with an older A700 which sits on a table with a ready 2xTC and 70-200G in my home office for any periodic passing wildlife. I shoot mostly on travel trips and most images involve landscape, wildlife, along with of course the normal family events, and the scale tips more towards a crop sensor as I like the additional reach. For now I remain confused over the A7 series differences, but I don't see any crop bodies. Not in any hurry to go full frame and then maybe find I need to add a longer telephoto to be happy.

I should have bought 2 A77ii's when they first came out new on that fantastic $800 deal with free vertical grip. I had no idea it would be a good as it is.

But I became very interested in this thread as I had smugly perhaps thought I would transition to a A7 of some model type despite their higher costs for how I use my cameras. I thought I would just naturally get an adapter to use my 5 lenses which over the years worked my way up to. The Zeiss 24-70, the 70-200G, a Minolta 100mm macro and 85mm 1.4. Oh and a Minolta 11-17 D. The 24-70 and 70-200 w/ TC are 90% of my shots. Go figure.

This is getting long - so I wanted to ask if I understood the details of this adapter issue as I understand them related to how I shoot: I think this latest new adapter will not allow my A77ii to take videos in any acceptable way, and may not allow shots in a darker setting say early morning or evening (I presume that to mean not well lit at all), or in a continuous shot sequence unless I set it in slow continuous. I maybe could live with these, but the requirement to shoot in 'P' or 'A' mode would be a deal killer if I could not shoot in 'A' mode and still change apertures. Somehow I learned this as my way of changing depth of field as well as shutter speeds and at times as adjustment to light conditions.

While the material I read over 2 hours trying to run these points down did not cover this point beyond saying it "would not work outside of 'A' mode". None of the material clarified if I could shoot in 'A' mode as I do now and still change apertures. "A' mode may be scoffed at by more prolific photogs, but it is a good crutch when I only shoot 2-3 times a year during a trip and in the quickness of the moment forget what might be better or take out some checklist ;-) and just let the camera compensate in anyway it needs to to help get the shot.

Has anyone tried the 'A' mode on the A77ii with this new adapter to see how strict or forgiving it is in this way?

Many thanks,

This adapter is to let you use your A-mount lenses on an E-mount body. It won't fit onto your A77ii or mine. How much functionality you get from the lens/body combination depends on both the body and the lens.

I think I understand your 70-200 is the version 1 G zoom, and were you to get a used a7ii, then Sony's compatibility promise (info from the UK website) is:
  • Available with a Mount Adaptor.
  • Operation sound of the diaphragm is recorded with the internal microphone.
  • Outside the A (Aperture priority), S (Shutter priority), and M (Manual) modes, the shutter speed and the aperture can not be adjusted during the movie recording.
  • If you attach the [A-mount lens] using the Mount Adaptor, MF assist function does not work automatically when you turn the focus ring. You can enlarge the image by selecting [Focus Magnifier] function or [MF Assist] function to any key in the "Custom Key Settings".
  • In order to use focal plane phase detection AF, the camera's system software must be updated to Ver. 2.00 or later. If the version of the camera's system software is 1.X, it is set to the contrast AF, and with an A-mount lens attached, the autofocus speed will be slower than when an E-mount lens is attached. (It takes approximately 2 to 7 seconds (based on Sony’s measurement standard). It may vary depending on the subjects or brightness of the shooting environments.)
If you get a brand new A7R1V, then for the same lens, Sony promise:
  • Available with a Mount Adaptor.
  • Outside the A (Aperture priority), S (Shutter priority), and M (Manual) modes, the shutter speed and the aperture can not be adjusted during the movie recording.
  • If you attach the [A-mount lens] using the Mount Adaptor, MF assist function does not work automatically when you turn the focus ring. You can enlarge the image by selecting [Focus Magnifier] function or [MF Assist] function to any key in the "Custom Key Settings".
  • When you perform continuous shooting in the Hi+, Hi, or Mid mode while the focus mode is set to AF-C, the focus does not track a subject. To enable AF continuous shooting by setting continuous shooting to Hi+, Hi, or Mid mode, the system software must be upgraded to Ver. 1.20 or later.
  • When you perform continuous shooting in the Hi+, Hi, or Mid mode while the focus mode is set to AF-C, the speed of continuous shooting can be slower.
You will have seen there is a good deal of uncertainty as to the exact meaning of all these promises. I have an EA5 on order, due to arrive in the next 5 days, and will post clarification on the compatibility with the A6600 body in this thread as soon as I have some hard, first-hand, data.
 
  • Outside the A (Aperture priority), S (Shutter priority), and M (Manual) modes, the shutter speed and the aperture can not be adjusted during the movie recording.
As you say 'uncertainty' indeed. If I understood most of the points correctly, some loss of functionality will not matter to me as I don't use the camera in some of those ways and don't anticipate it. As I tried to show I am rather simple in my approach to taking photos yet still want good IQ. The particular note above from your post would suggest in movie mode using A, S, and M modes I could use aperture changes in the manner that it is written. If so, then a step further would suggest for stills I could use aperture adjustments as well. This was the deal killer if I could not shoot this way and I would be moving on.

I think I will just lay low and keep my ear posted to this forum and see how it shakes out with this adapter. If Sony wanted to maintain a barrier to prohibit folks from moving over to their E mount bodies with their previous A mount lenses, that would end my 40 year association when I am through with my A77ii for whatever reason. This transition worked well from the M/K7D and Sony digital bodies so far. I read someone's post that stated it could not be technically done. Buying all of the same equivalent quality lenses and a new E mount body would turn me away. I like the lenses I gradually acquired and would prefer to keep using them with a new E mount body and would certainly continue with them if I could. I am sure many folks are in this similar position and wonder similarly.

Thanks for your reply.

Having A99MII working with A7rII, I found A mount lenses are better go with A mount bodies.
You should try the A9 with SSM II lenses. Using the A9/LA-EA3/70-400SSMII the C-AF is way better than on the A99. There is no comparison at all. I have not tried the A99II, but I can't imagine it to be better than the A9 with LA-EA3. The SSM I-series motors don't give the same AF speed.
Quite sure the a9 is the fastest thing around... but I did try a friend's a7RM4 last week with LA-EA3 + SAL70400G2 against the SEL200600G at 200 and 400mm and there is no comparison. A-mount glass will never be faster that E-mount glass on E-mount cameras.

Friendly reminder, the SEL200600 isn't the fastest focusing lens around. GM takes the crown.

So for A-mount users, A99II is probably the best option around. Too bad the precision can suffer from lens to lens if you don't calibrate it properly (and at 42Mpx, that's very critical)

That wasn't Marcus' point, though. The question is whether A mount glass on E mount can be better than A mount glass on A mount. Showing that native E mount glass is faster on E mount doesn't prove or disprove anything... and AF is more than just speed... it's also lack of hunting, accuracy, tracking, and coverage.
