I still maintain that the market has turned from the old days when all the big money was in lenses... These days people are more inclined to upgrade bodies because new bodies do give better image quality, than they are to buy lenses...

Sony want to sell solid state bodies that offer a good profit margin, and their interest in lenses is (largely) to make sure that there is a market for their camera bodies.

The positive side of this for us is that Sony are interested in filling in gaps or making really interesting lenses.

I stress I think there is still money in making lenses, I just think Sony has realised that there is more money in bodies...

I think so, but I need to use my R more. The Sigma 35/1.4 showed strange artefacts and I had to turn off lens compensation to use it properly.

Of course better is always nicer you use a Sony camera with a Sigma adaptor and a Canon lens, it is a wonder it works at all!

Like Jonas said: Sony prices are comparable to the prices of the competition.

Looking at the EOS R again today reminded me that it is closer to the A7II than the A7III.

Sigma seems to know the EF protocol pretty well (and didn't understood A-mount.) Their MC-11 has been very reliable with my unsupported lenses. Maybe I'll get a supported lens eventually.

I feel it is (slightly) better then the A7r2 I own. I guess it is somewhere in between the A7r2 and A7m3 (without ever having used the A7m3).

I think they know it pretty well - that was not always the case. With most Art lenses The-Digital-Picture reports good AF accuracy, though he reports that the Sigma 105/1.4 DG HSM Art suffers from inconsistencies depending on the camera.

Like I said, I do not have the A7m3, I own the A7r2 and the A6400. I do not know what EF lenses you own exactly. I know you own the 50/1.8 II, but I find this a problematic lens. I know you have used the 85/1.8 USM, so, I tried that lens. I also added a modern lens (the 24-70/4L IS) and the Sigma 35/1.4 Art. I used the Sigma MC-11 and the standard Canon Mount Adapter EF EOS R.

Canon 85/1.8: the A6400 and R are comparable (good), the A7r2 less so (usable).
Canon 24-70/4: the A7r2, A6400 and the R are comparable (very good to excellent, the A7r2 probably is the lesser of the three).
Sigma 35/.14: the A6400, A7r2 are excellent, with the R it is very good.

Everything is just a quick test, nothing really serious. Do not attach too much relevance to my labelling, I think it mostly is to distinct between the behaviour.

Some remarks:
The Canon lenses don't do follow focus with the A6400/A7r2, the Sigma does.
The AF behaviour between the R and the Sony's is different.
One surface I (wanted to) used did not work with the R, both Sony's mostly focused on the surface, but the Canon R did not.
The R resets all lenses to infinity when you mount them - just like Sony/Minolta A-mount but unlike Canon EF-mount.
I really like the viewfinder of the R.

I just recieved a Sigma 12-24mm F4.5-5.6 EX DG HSM that doesn't AF on either my Canon EOS Rebel S II or the MC-11. The serial number is much lower than the the one I have that does AF.

Thanks for the testing. I don't have the 50/1.8 II.

I have these EF lenses:

Canon 28/2.8 IS, 40/2.8, 50/1.8 STM, 50/1.4, 85/1.8, 100/2, 22-55, 28-105/3.5-4.5 II
Sigma 12-24 I, 20/1.8, 50/1.4 EX, 400/5.6 APO
Tamron 45/1.8, 70-300 USD

These all work fine on the MC-11 + A7II.

Ahoy there!

Until such a time that there are no A-Mount bodies or lenses, then it may be time to change brands or mounts, so until then, why is this so important?

If 3rd party manufacturers stop supporting the A-Mount, then that would be a clear message of intent which will likely be result of what Sony have announced, but beyond that, the system will go on for decades, after all, we're still using, buying and selling mid-80's Minolta glass and DSLR's and there's enough lenses to suit all budgets and lens types that the vast majority will have the types needed.

Maybe my view is too simplistic, but it's my personal opinion right or wrong otherwise why not change brands now? I don't see compact systems being the weapons of choice for dedicated shooters and/or semi-pro, pro and/or those who are keen amateurs or hobbyists.

Until my gear needs to be euthanised by lethal speculation, then I'm as happy with my gear now as I was when I bought it. Just my tuppence worth.

I was under the impression that this has already happened. I don't find it troublesome; I'm just curious. What are the most recent A-mount-specific lenses or accessories that have been introduced by any manufacturer?

Tamron released their 85/1.8 and 150-600 G2 in 2017.

I believe someone introduced a non-electronic A-mount lens since then that is not in our database. Most of new non-electronic third party primes haven't come in A-mount.

Just checked that using the dpreview database for lenses:
- Sigma abandoned A-mount 2015
- Tamron abandoned A-mount 2016 (last announcement February)
- Laowa/Venus Optics F/2.8 12mm seems to be the last A-mount lens announced: July 2016.

And yet, I can buy Sigma A-mount lenses everywhere... Abandoned is to strong, they stopped investing.

BTW, the Tamron 85/1.8 was released in A-mount in 2017 according to our lensdatabase.

The A-mount versions of the Tamrons were available about a year after the Canon and Nikon versions. They even mentioned this delay in their announcements for those lens.

you can only buy a few ART lenses on A-mount. A good majority of ART/sport/contemporary lenses from sigma don't have a-mount version.

Yes, correct. Even less in K-mount. What are you trying to say?
