BTW, I finally managed to get LA-EA 5 shipped to Israel and I received it 2 days ago!

I was surprised how the combo of a7RIV + LA-EA5 + CZ 135/1.8 (and also 85/1.4) feels comfortable and natural in my hands. It is not the bulky LA-EA 4.
The AF works pretty well. I got some out of focus photos when the kids were moving around (although I used AF-C and Eye-Focus) when using these lens wide-open, but on my native a-mount cameras (a900 and a99) it is more or less the same rate of missed-focus in such situations. When the kids are more static I get great and extremely sharp photos with focus right on the eye! I tried it for candid shots of the kids, but for studio shots or staged shots when you can ask your subject to stand still for few seconds it is great.

But it is a bit annoying that it works only with the newest cameras, that we still have delay when aperture is closed down and it still doesn't work with TCs.

As my 'insurance policy' against my a-mount cameras dying and not then having to ditch my extensive a-mount lens collection, I took advantage of Sony Australia's special half price offer to buy an LA-EA5 adapter around Christmas and finally took delivery.
Out of curiosity, i borrowed my daughter's a6400 camera to do some test shooting.
The adaptor is quite compact, but out of my unfamiliarity I find the a6400 feels very small.
Nevertheless, my a-mount lenses mounted on it work fine.
The only ones that AF are the CZ 50mm f1.4, CZ 16-35mm f2.8, CZ 24-70mm f2.8. Sony 70-200mm f2.8 G2, Sony 70-400mm f4.0-5.6 G2, and Sony 300mm f2.8 G.
The following are only manual focus: CZ 85mm f1.4, CZ 135mm f1.8, Minolta 500mm f8 Reflex, Sony 100mm f2.8 Macro.
I find it odd that the 50mm autofocuses but its 'big brothers' the 85mm and 135mm don't. I would have thought their mechanical focus mechanisms are the same.
If I get interesting enough photos, I might yet post a few.

I can confirm that your CZ 135mm f/1.8, 500mm f/8, and 100mm f/2.8 macro lenses should work with the LA-A5 and a suitable body - at least my copies of those lenses work with my A6600 and A7Riv as expected.

The 500mm seems to be slower to AF on the A7Riv than I remember it on my A99ii - but I haven't tried them together so it may have been poor subject choice for the test. When I'm allowed to go somewhere interesting I'll try it again - COVID-safe, socially-distanced, street photography?

The 100mm macro is never a quick focussing lens, and that hasn't changed.

The CZ 135mm was, as always, a pleasure to use.

You're welcome to see how your lenses feel on my A7Riv some time; otherwise you'll just have to give your daughter a generous birthday present so you can borrow hers occasionally.
A9 | A7Riv | A6600 + 1018 | 1670Z | 18135 | 2470Z | 70200G | 70300G | 70350G | 200600G
28 | 55Z | Σ56 | 85
Surplus - A99ii + 1635Z | 2470Z | 70200G (and a few more)

Anyone care to guess whether the screw-drive capability of LA-EA5 will be enabled by firmware update on A7x M2 and M3 models?
Realistically, how likely is that? Did the later cameras need some hardware changes to make it work? or does the firmware necessary conflict with something else (or is resource-limited)?

0% chance.

Sony never allowed the NEX 5R, 5T, 6, A5100, A6000, or Alpha 7 to use phase-detect with the LA-EA1/LA-EA3. The A6000 focuses better with the Advanced mode of the Metabones than the A7II. Sony even released a new firmware for the A6000 in 2019.

The A7C and A7SIII were both released without it.

They want you to buy the A1, A7RIV, or A6600 -- highest margin products.

The MonsterAdapter LA-EA4r project is progressing.

The tripod foot of the LA-EA3 annoys me enough to consider the LA-EA5.

Thanks for that, Mathew. I'm replacing my LA-EA2 with a 4 but wondered if it was worth waiting. Sounds like it's not, and I'm not buying an M4 camera just so I can buy an LA-EA5 instead.

I'm wondering if an LA-EA5r monster adapter would work. If it had the same chip as the LA-EA4r, how would the camera know it wasn't one?

I guess the LA-EA5 drive motor would need to have similar electrical connections to the 4 or else a modified chip would be needed.

The LA-EA5 doesn't even have the room to physically fit the LA-EA4 PCB.

@Miranda F The Monster Adapter team have stated that they are examining how the LA-EA5 works, on their facebook page. Presumably to see whether they can learn something that could be added to their LA-EA4r adapter firmware. But it could also be to see whether there is any way to hack the LA-EA5 to work on more cameras (who knows?).

However they have so many projects nearing completion at the moment, it might be a while - adapters for Pentax, Nikon lenses are coming, and presumably they are looking at further development of firmware in them too.

Finally, there are issues arising with the latest update to the LA-EA4r V4 probably because of different models of the LA-EA4, and they are trying to sort those out. Updating from V3 has resulted in some lenses behaving peculiarly, particularly the Mino 135 f.2.8 and the 500 f/8 on some adapters.
