p.1 #1 · Sony a7R ii vs. A7 iii for Canon EF lenses?
I am looking for a suitable Sony body to use with my collection of EF-mount lenses. I have bought the Sigma MC-11 already.
There are Sony sales at the moment with the a7R ii going for $1300 and the a7 iii going for $1700. I honestly don't know if the latter model is worth the extra $400. Any tips from trailblazers in the "Sony mirrorless body plus non-native AF lens" area?

my a7rii works very well with many EF lenses. some not so well. for example, works AWESOME with new late model 50 1.8 stm. focus hunts badly on 50mm 1.4. i think the newer lenses work great. it also works great with my 85mm 1.8 and 40mm pancake.
It also depends on the lens. eye AF is disabled obviously. i use the sigma as well. With sony lenses, the AF and eye af is superior in the a7iii but the photographs lack the resolution of the rii.
The a7rii (and riii for that matter) is an amazing deal right now and basically only compares to the R5 and the 5dsr on the current market in terms of stills.

The bigger battery alone is worth the jump to the A7iii. The af improvements and button layout is nicer too.
Depends on what one shoots. The nice sensor of the A7R2 is the most important feature for my landscape photography. That and the apps which as available on the A7R2 makes it a much better camera over the A73, even if you don't take into account the $500 in savings.

I haven't used Sony but it might be hard to pass up the higher resolution body.

Personally, I would first take a hard look at my probable use cases — what do you primarily shoot — and then work backwards from there. I initially got excited at the prospect of increasing selection by using adapted lenses — until I started to photograph birds. Wildlife and bird photography probably won’t consistently focus fast enough with an adapted lens and you may just be better off with a native lens (or staying with your current system). But if you shoot landscapes, this may not be a real issue. Hope this helps.

I had the R2 and switched to the A7iii and one of the main reasons was the better af, specially with canon lenses.
The R2 does not do eye af in af-c (only sigma lenses with mc-11 or any lens with Metabones in advanced mode but painfully slow).
I like the A73 much more than the R2, besides the af, the colors are much better.
And still for af, you will find issues with some lenses. For example, the 50 stm is not accurate focusing outside the center. The 40mm only focus in a center portion of the frame. The sigma 35 is also not accurate near the edges.
In general, none of the adapted lenses will focus accurately or focus at all near the edges. Depending on the lens, they will focus in a bigger or smaller central area.
Other example, the 70-200 f4 focuses at a big portion of the frame at 70mm, but zooming in, it will only focus in the central area.
This makes lenses hunt forever if you're focusing faces in af-c and they move outside the center for example.

in addition to what numbertwo said, both bodies will be limited to about 3fps af-c or less... you'll need to step up to a9/a9ii to get 10fps af-c.
even with that limitation tho, the 3rd-gen sony bodies are a big step up in af with adapted lenses... how much that matters depends on what you are shooting, as was pointed out earlier in this thread.
unfortunately it's a big jump up from $1700 to $3000 for the a9.
i found it to be worth it tho, the sony stacked sensors are still unequalled for both af and real-time/blackout-free evf readout.
not all canon-brand dslr lenses work perfectly on milc of course, even the v1 versions of those lenses are not supported at 12fps on the r5.

If you take pictures of people... the lack of eye-AF support, when using Canon lenses/MC-11, on the A7Rii is a problem. The A7iii will be able to eye-AF with this combo. As others have said, the only exception (aside from just using native lenses) is Sigma Art lenses - those are the only Canon-mount lenses that will eye-AF on the A7Rii.
If you take photos of landscapes... the A7Rii will give you a little more sheer detail. But the A7iii is no slouch.

Thanks to everyone who replied. I wound up buying the Sony a7R ii because I couldn't justify the incremental cost of the a7 iii: The former went on sale for $1198, and the latter was about $500 more, even priced for Black November.

I recently got the RII recently because of that sale too. It is a nice old camera. I can get by with it. But the A7III is far more advanced for AF-C. The phase-detect of the 7III is much better than the R's especially in low light.
