p.3 #1 · p.3 #1 · A7RII and Canon lenses AF compatibility

One more thing to consider is what AF modes are actually available with the various adapters. For example, in movie recording, some adapters cannot do continuous AF unless you half-press the shutter, which is of course, a problem for shooting videos. And some adapters can't do some AF modes like Continuous AF, Automatic AF, DMF, Lock-on AF, Eye-AF, etc.

If I'm buying the A7R II for all its advances in AF, then I sure the hell wouldn't want any of AF features crippled by using an adapter. And this is precisely why I'm still on the fence. I love high-end standard zooms (such as my EF 24-70mm f2.8 L II on the 5D Mark III, and Zuiko 12-40mm f2.8 Pro on the E-M1), but on the full-frame E-mount, only the 24-70mm f4 is available, and I just don't know if I'm willing to lose an entire stop. There's supposedly a f2.8 version coming, but who knows when that will be?

We know that you can't use lock on continuous auto focus. I'm not sure what mode this is called. I've read three reports now that mention the Canon adapter does not work with this mode. Only native lens work.

Someone reported on DPReview.com that eye tracking and smile detection either did not work or were grayed out.

Can anyone confirm?

I can confirm that eye tracking, smile detection, and lock-on AF are not available.

Wide AF, center AF, and flexible spot are available. I've had the best luck with wide AF, although I'm not sure how to tell what it's going to lock onto or how to control it. Flexible spot sometimes works. (I've tried with a Metabones IV, latest firmware, and a 100-400 II and 24-70 II.)

TheEmrys, I'm going to be trying some A-mount lenses this afternoon (specifically the 70-400 and 500) if that makes you feel like less of a tool :P

Only sometimes? That doesn't sound too encouraging.

Read somewhere that Fotodiox has been teasing a new version of their adapter that will do continuuous AF and will AF in video.

I'm curious if this is a deal breaker for some people. Other than landscapes or stationary subjects it looks like you lose a decent amount of the AF capabilities of A7R. What a bummer...

I assume you tried both of the Metabones modes? I think there is a green mode and another. I don't own it yet.

What works today and what works in three months and six months is likely to be very different. The adapter manufacturers are going to have to put in some work to get more lenses working and the ones that are working working better. Expect prices on adapters to go up, but expect performance to go up too.

yeah, it would be nice if some long stuff like that and/or super-tele plus extenders worked to take advantage of the high pixel density for more reach for distant widlife

Most of my Canon lenses are on the list of those not working well. Add to that that EOSHD says AF with Sony lenses is improved over the A7R but still not great and I'm seriously wondering if I upgrade anytime soon, if at all. If AF isn't up to the speed of a top DSLR or my Olympus MFT, I'll probably wait for the next version.

Sony only claimed a "40% improvement" so I wonder where people got the idea with would be a DSLR focus killer?

At 3200 dollars I would imagine some thought there would be a lot of meat put into he camera to justify the cost.

Canon lenses will never AF perfectly well on an adapted Sony body. Usually adapted lenses are MF only.
IMO, what is happening is actually a little miracle with some Canon lenses in AF mode. For, example I just tested it with my 70-200 f/4L IS and was impressed. AF was fast in good light and OK in low light. I consider this a bonus.
Some lenses will do better than others but if your perception was to get the A7RII and autofocus with all your Canon lenses for critical work, you will be very disappointed.

I watched the video showing fast focus in in dim light inside a few times. I got the impression it would be pretty good. The 24-70L II does good and also inside in dimmer light for me. Such is life. If this was anyone's only worry they would be lucky in this world. :^)

Has anyone tried the new A7R II with the Commlite adapter. Many people found this to be better on the previous Sony bodies than the Metabones adapter. It's also a quarter of the cost. Anyone

Also.....not that they're AF, but I was hoping to use the new A7R II with my Canon 24mm TSE (tilt shift) and a Schneider 50mm (tilt/shift Canon mount). Anyone try either or these out yet? Curious about vignetting and resolution with the larger sensor.

p.3 #20 · p.3 #20 · A7RII and Canon lenses AF compatibility

I'm quite confused by the Metabones IV firmware. I bought mine a few days ago direct from Metabones in Hong Kong, the T version, and it arrived with 0.41, which is the latest version listed in the change history on the website, BUT the app offered an update to 4.20, which I applied. It now shows that it has 4.20:


	http://www.cloudedforest.com/sharedfiles/mbfirmware420.png

I don't actually have a camera to use the adapter with to know if it still works, but I haven't seen anyone else mention having this firmware, and I don't understand why everyone else is talking about 0.41 being the latest and I seem to be the only one with 4.20!

Also, "centering" of these adapters has been discussed, and I have a friend who has some micrometers, so I used one to measure the flange separation in 6 places, where each bolt is. These were the measurements:
25.86
25.83
25.80
25.88
25.86
25.84
It's a little tricky to measure because the radius of one flange is smaller than the other, so you have to have the micrometer over the outer edge of the smaller flange, and over the inner edge of the larger flange. Measuring in the same location more than once I was seeing a varation of 0.03, so the above figures seem fairly reasonable compared to that. I don't know how much variation is needed to cause image softness?
