Sony a7iv

Dune wrote: The screw drive lenses I have are the 500mm mirror and Minolta 100-200mm F4.5 zoom.   They both work as well as or better in the case of the 500mm as they did on my A77. I also have a couple of A mount lenses with motors in them, 70-300G and a Sigma 105mm macro. Both also work well with it but of course I could have used a different adapter with those.

Thank you! That's good to know! It's definitely something I'm contemplating down the line.

Thanks for those pics Joe. What was the AF setting you used for those? It looks like combining the a7iv with an LA-EA5 adapter is a very effective combination.

Thank you, Joe!

The photos look great! I'm wondering what the difference is between the LA-EA3 and LA-EA5 when used with SSM lenses. I understand the LA-EA5 is not compatible with my A7III. The LA-EA3 seems to work fine with My SAL 70-200 SSM G (original). Mind you,normally the fastest moving objects I photograph are trains. So I wonder if I were to upgrade to the A7iv or other newer camera, will I need the LA-EA5 for SSM lenses?

Ah, Ok! Thank you Matthew!

I don't have an older A7 right now, but I have a NEX 5T, and the LA-EA5 works just like the LA-EA3 (and updated LA-EA1) on it--right down to having contrast-detect AF-S in movie mode when you press the shutter--the most recent Sony bodies no longer have any contrast-detect with the LA-EA1/3/5 adapters.

Another set of even more recent cameras dropped all AF support for the LA-EA2 and LA-EA4 adapters, but those cameras still support all the non-AF stuff with those adapters. They didn't just drop all support for those adapters.

Summary:

NEX to A5100/A6000/A7/A7R/A7S/A7SII/A7II(original firmware)

- Updated LA-EA3 and LA-EA5 support 11/10 FPS HI+ frame rate AF-C
- LA-EA1/2/4 and original firmware LA-EA3 limited to LO frame rate AF-C
- Still no AF with original firmware LA-EA1

A7SIII/FX3

- LO frame rate AF-C
- No LA-EA1/3/5 contrast detect/video AF-S
- No LA-EA2/4 AF support
- No LA-EA5 screw-drive AF
- Still no AF with original firmware LA-EA1

A1/A7IV
- LA-EA5 screw-drive AF

Interesting. Though the LA-EA4 kind of sucks and the LA-EA5 is way better so I'm not sure why anyone would want to use it with them!

I vote for you.
It is a disappointing specification for those who already have LA-EA4.
However, LA-EA5 brings out the modern AF performance of the latest body. Maybe future progress too.
The LA-EA4 pushes AF back to the old standards it was designed for, no matter how good the new body is.

Without the LA-EA5, I would have been dissatisfied with the AF performance and sold off all the A-Mount lenses. But thankfully there is LA-EA5!
