Just had a slightly useless response from Sony customer services about whether the AF performance with the APS-C sized LA-EA1 will be identical on the A6300 as it is with the full-frame LA-EA3 mentioned by Sony in all its literature.

We are sorry to inform you that we do not have sufficient information in regards to the Sony (ILCE-6300) camera as the product has not been officially released yet.

As far as I can tell, when using APS-C lenses, the LA-EA1 performs the same on the A7rii as the LA-EA3 so I'm hopeful it will be the same with the A6300 - but I can't get any confirmation.

If the price of the LA-EA3 falls as it has done in the States then it may not be an issue but currently it's prohibitively expensive when you can pick up a 2nd hand LA-EA1 for around £60.

I recently (just two days ago) used LA-EA1 and LA-EA3 on A7ii and I could not tell any difference what so ever in the AF.

I imagine this will apply to A6300 too.
From what I know LA-EA1 and EA-EA3 are identical apart from latter not vignetting with FF lenses on FF bodies. The same applies for LA-EA2 and LA-EA4.

I prefer LA-EA1 because it has a removable tripod foot unlike LA-EA3.

LAEA1 can basically be converted to an LAEA3 by removing the baffle and taping some wires down (so they don't hang in the optical path). There's a little bit more to it, and I've heard it can suffer from internal reflections in some situations, but that's about it.

OTOH, I believe the LAEA2 and LAEA4 have different mirrors in them, and I think (although I've never had the opportunity to test it), that an A7 camera with an LAEA2 attached will default to APS-C crop mode, regardless of what lens is attached. (Not sure if the LAEA1 does that)

Also, according to some spec sheets I was looking at (may not be reliable sources of information), the LAEA4 is actually lighter than the LAEA2 (by approximately 40g, IOW, the LAEA2 is 25% heavier than the LAEA4).

At current US prices for the LAEA3, I wouldn't bother with an LAEA1 unless is was a super bargain. If the price of the LAEA3 hasn't dropped in your market, it might be a harder decision to make.

Only works for shorter focal lengths (I don't remember exactly but up to about 80-90mm-ish). I tested it with minolta 24-105mm on A7.
Even on shorter focal lengths there is a little vignetting, but its correctable in PP.

As mentioned above, LA-EA1 has a removable tripod foot which I really like. That's reason I bought it even tho I had A7 and thought I could convert it to work like LA-EA3. But that doesn't work very well for all lenses, but I ended up moving to APS-C in the end anyway. Kinda worked out nicely for me.

Just re-reading this old thread: I had wondered whether the LA-EA1 would still receive firmware updates as the LA-EA3 does or whether there would end up being a real difference in the electrical behaviour. It does appear so:

LA-EA3 v2.0 is dated 25/05/2017 (for the A9 fast mode)

LA-EA1 v2.0 and this last update is from 2010 (for camcorders).

So presumably the previous comments in this threads are still valid for basic performance, but if you want all the latest bells and whistles you need the LA-EA3.
Miranda F & Sensorex, Sony A7Rii, A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras ...

You'll need the LA-EA5 for al the latest bells and whistles. I do not expect the LA-EA3 to get any firmware updates now the LA-EA5 is out.

I did a quick test with the LA-EA1, LA-EA3, the 18-135 and the 24-70/2.8 on my A7r4. I think the LA-EA3 might be ever so slightly better? I am unsure, the test was limited and therefore not conclusive at all.
