    Posted: 23 August 2018 at 01:15
I have one of these sitting around not used for a very long time and suddenly have a fast need for a wide FF lens on a budget - which is not available in E Mount at all. So I was thinking an old Minolta 35mm lens that has AF.

As far as I can tell the LAEA3 (I have in hand) will only AF on Sony SSM and SAM lenses though so I may be out of luck.

Yes I could get a different adapter - but I literally only have 2-3 days left in which to find something. Otherwise I'm shooting 24mm only. The worse case is something wide on 2/3 format but then I would need even wider.

Any suggestions?

A search through the lens database reveals just two that meet your requirements: Sigma 35 f/1.4 DG HSM Art and Tamron SP 35 f/1.8 Di USD.

The Sigma Art 35/1.4 AMount works very well with LAEA3 and a7RIII. Just about as good as the FE version.

You could manual focus the Sony 35/1.4, and retain all smart connection. It's a good balanced fit on EMount.

Do you not have any zooms that cover this range? The Sony 28-75mm F2.8 SAM is fully supported on the LA-EA3.

Thanks everyone for the quick replies!    I mentioned at the end of the post - but I should have mentioned specifically - I already have a 24mm (24-70 2.8 GM) - so I was looking for something actually wider.

But - this is to put on a FF E-Mount second body... something small that's FF and autofocuses is the hope...if the LAEA3 would work.    Would a SAL20F28 have AF this way? It seems like maybe not....

There's also zooms like - Tamron AF 17-50mm F/2.8 XR Di-II LD SP

But it has to AF. This will be used for a few special effects WA look to supplement the regular shots.
The lens quality is secondary, so affordable is key too - otherwise there are expensive options - it's mostly for the crazy fun wide group action type shot.

The Tamron 17-50mm F2.8 won't AF on an LA-EA3, and it also doesn't cover full-frame. With an APS-C crop it is less wide than a 24 mm.

The SAL20F28 is identical to the 1986 Minolta AF 28 F2.8 and won't have any AF on the LA-EA3. There are no A-mount primes wider than 24mm with an AF motor.

The Sigma 12-24 HSM, Tamron 15-40 USD, and CZ 16-35 SSM are A-mount full-frame ultra wide zoom options--none of which is particularly inexpensive. The Sigma 10-20mm F3.5 HSM might be your cheapest wider than 24mm AF option with the LA-EA3. It might even cover full-frame at the long end.

The Samyang AF FE 14mm F2.8, Zeiss Batis 18mm F2.8, Tokina Firin 20mm F2, and the 21mm ultra wide converter for the FE 28mm F2 are the FE AF prime options.

This is what I was responding to:

Communication is funny sometimes!

Much thanks again - OK everyone is pretty much confirming what I was finding.... There really aren't inexpensive options out there. The Sigma 10-20mm F3.5 looks like the most affordable, though not very fast.

Yes, sorry about mentioning Minolta 35mm (format) it did confuse things.

Most of them, (adding the cost of the adapter), lead me back to eventually just getting a native FF E-Mount lens. For now however it's going to have to wait as I'm still recovering from the purchase of a 70-200 2.8 GM.

Don't use E-mount body, but I heard that it is possible to mod the Sony E16mm f2.8 to be used in A7, a link. I saw the modding quite popular at the early day of A7 series when there were very few FE lenses.

hey Guys,

have some questions about the LAEA 3/4 Adapter as well:

I own the a900 with

- Tokina 17mm 3.5
- Minolta 20mm 2.8
- Sony Zeiss 24mm 2.0
- Sigma Art 35mm 1.4
- Sony Zeiss 50mm 1.4
- Sony Zeiss 85mm 1.4
- Minolta 100mm Macro 2.8
- Sony Zeiss 135mm 1.8
- Minolta 200mm 2.8 APO HS (+ 1.4 Minolta Teleconverter)

I plan to upgrade my Body to the a7iii. Are these Lenses usable without any problems on the LAEA3 adapter?

best regards

Some of these are screw drive lenses, and as such need the LA-EA4 to autofocus. The LA-EA3 will work, but in manual focus only.

@Ziegengeist

I think only your 24/2 35/1.5 and 50/1.4 will work in AF on the LA-EA3. Should be fine - probably better than on A900, but some lenses seem to work better than others.

Like Stuart says the 4 is what you'd need for the rest. Reduced functionality and doesn't seem like it will ever be improved by Sony (if it even can be). Whether that would work for you would depend on what and how you shoot.

I was wondering if AF on the LA-EA4 (which is said to borrow from the A65) is on a par with or better than that of the A900. The fact that it's designed for a crop sensor implementation may be a factor to consider of course.

Nothing is as good as the center double cross AF point of the A900. It is better then my A77m2 focus points - only the spread is less. I feel the A99m2 is comparable.

I am not convinced the A7m3 will be better then the A900 using the center focus point and dedicated lenses.
