    Posted: 19 June 2019 at 17:01
Just purchased a Sony A7Rii from Ebay and it arrived this morning along with my LA-EA3 adaptor.
I only have Sony A mount lenses as I still have 2x A99, A77ii and A900 and after researching the internet I was not sure how it would work with my Sigma lenses
It worked fine with all of them focussing fast and with no discernable difference to my A99
They were
Sig 12-24 II HSM
Sig 35 art
Sig 24-70 HSM
Sig 70-200 OS HSM
It was the 12-24 and 70-200 I was most pleased about as the info I could get on the web was not very favourable.
So no need to rush out and buy E glass at the moment

There is a native e-mount sigma ART 35 in sales if you want one

The main drawback to using adapters on A7RII is you lose eyeAF and all the advanced AF tracking modes like expanded flexible spot.
You also lose DMF.

Not to fussed about DMF but eye AF would be good but I'm happy with the range I have with my existing lenses 12-200mm. I'm looking at maybe adding the Zeiss 55mm 1.8
Update the 70-200 OS HSM doesn't always focus spot on

FE55 is a very good lens. It's definitely worth getting at least one native lens from Sony, sigma or tamron to test out the native AF.

Hi Dave18, have you tried Sigma 12-24 II HSM in video mode, does it autofocus using LA-EA3? I have A7iii and looking to get one sigma 12-24 II HSM but need to know about focusing when shooting videos...Thanks.

There is no continuous video AF with any adapter that emulates (or is) the LA-EA3. AF-S is available while recording video. You can keep initiating AF while recording as often as you want. For AF-C you need an adapter that tries to emulate a native lens or the LA-EA4 (with the usual SLT limitations).

My EF Sigma 12-24 EX DG HSM I focuses fine on the MC-11, but no AF-C for video. The 12-24 F4 DG HSM Art should have AF-C for video on the MC-11, but even then Sigma doesn't claim to support AF-C on the MC-11 at all.

I see, so as for recording video, it's better to get some native lenses for e-mount than try to run an adapted one...I'm going to stay with Sigma 10-20 APS-C for now and manual focus...

If you plan to keep the a-mount set, I understand it looks attractive to work with the adaptor for the A7Rii.
At the same time, to get most of the fun that the A7-series are offering, E-mount lenses are the way to go in my opinion. (Over time, for me, it has resulted in selling all of my A-mount stuff, except for an a100 out of nostalgic feelings.)

Eye-AF and such have been mentioned above. For me, an important aspect is also size and weight. If I combine my A7Rii with a simple Samyang 35/2.8, I get stunning 42Mp shots out of a pocket size camera. An adapter immediately changes the feeling of size/volume. This is also the case with a fairly compact zoom lens like the 24-70/4 G (which is hugely underrated i.m.o., mainly because of the unfortunate initial combination with the first A7-series).
