A7RII autofocus test: Commlite and Fotodiox Pro Adapters

[pdrphoto]

Hi!
Maybe you can find interesting an autofocus test I've done with Commlite and Fotodiox Pro adapters and Eos lens on the A7RII.

 

Finally I can say that the Fotodiox works good only with a restrict number of lenses.. but (when it works) it works great!
I've tried it with: Canon 50 f1,4 - C 100 f2 - C 24-70 f2,8L - C 50 f2,5 macro - C 90 f2,8 T/S (manual) - Sigma 35 f1,4 Art.. It works bad with all the lenses except for the 24-70 f2,8L. For "bad" i mean not only for the autofocus function but also for the aperture controls and the stability of the Camera.  With the Canon 24-70 f2,8L, instead, it is impressive!... it is as fast as working on Eos body (only with some rare fails), and very reliable. 
Also it doesn't work with the A6000.

The Commlite is like a workhorse.. it works good with all the lenses and with the A6000; but it is not so fast like the Fotodiox and not so accurate.
 

Here you can find the video tests:

Hi!
Did you tested in morning lightt / outdoor?

I find that outdoor works remarkably better that indoor.
In the indoor test i used a 3/4 backlight to see the reliability of the autofocus.

Just a quick question here, I'm wondering if the 399 points pdaf wide can be used with the adapter right? since all the reviews I've seen they used only the centre spot so I'm not quite sure 

 

thanks

[pdrphoto]

Yes.. the wide option works fine.
I will make some additional tests in this weekend, especially for focus tracking.. anyway i can say that i preferred the centre spot for focus test because it gives the right feedback to evaluate the performance.
But, using all the autofocus area, with good light all performs right.

Again the Commlite is the workhorse and the Fotodiox is the faster but "fussy" one.

commilite for me works  great only with 24-70 ,24-105,70-200 f4 is 

with 50 1,4 100 2,8 macro 135 f2 never works AF  always hunting .

[Aonko]

I have tried both as well, and I prefer the commlite since it works with more of my lenses. I have found some lenses only work properly AF with phase detection turned off and contrast detection turned on, so if you have a lens that is always hunting for focus give that a try.

[studiov1]

thanks i will try those settings and i hope that works better with primes.

[Emptymind]

I just got the Commlite to test before ordering the Metabones - and it may just do instead. I just tried it with an EF Sigma 18-35 and it works well - AF is useable. My EF Tokina 11-16 works in Manual focus only so it seems.

Can you identify the firmware versions of your adapters please? Thanks.

[pdrphoto]

I think it's impossible..

[cyberstudio]

Sorry for not being clear but with a lens attached just navigate to the last page of the MENUs and find "Version". The version number of the adapter is listed under "Lens".

[pdrphoto]

Ok!
I will check asap

Hi New here, just got the a7rII   .....(finally :-)  )   .....noticed you've used the new sigma 150-600 .......so it worked well right across the zoom range ??   ...was thinking of going for the A Mount Tamron 150-600 and using the la-ea3 adapter but id rather go for the sigma?? ... could you confirm it work well???

 

cheers

Hi I have the A7RII and the Fotodiox Pro. I mostly use my Canon lenses in manual, but have tried a 15 year old Canon 28-105  f/3.5-4.5 II USM Lens. And it's autofocus Works in all but macro, about 80% of the time. And I find that amazing for such an old lens.

Sorry for not being clear but with a lens attached just navigate to the last page of the MENUs and find "Version". The version number of the adapter is listed under "Lens".

Most adapters do not properly populate this field.  For example I am fairly certain that my Viltrox and my Fotga adapters both report "31" (I know one of them does...) - which I think may be the maximum version number that can be reported.

 

That's a big issue with many of these adapters - they keep on getting revised in both firmware and hardware design, and in fact I think many of the adapters on the market are just clones of each other.

 

It would actually be more useful for someone to pull these adapters apart and look at what's inside.  For example, for one of the FOTGA adapters and also the Viltrox EF-NEX II:

http://www.dpreview.com/forums/post/56168030 - FOTGA, CPU is a lowly Atmel ATMega8, there are some SERIOUS design deficiencies in the pogo pin springs for the EF-mount side of the adapter that results in frequent stuck contacts (which will cause all sorts of weird failures...)

http://www.dpreview.com/forums/post/56172662 - Viltrox EF-NEX II.  Much better design/construction, uses an NXP LPC1114F/302 (which is a midrange 32-bit ARM Cortex-M0 CPU)

Thanks for sharing results everyone, helps people like me to decide! =) Not sure which one I will buy yet, but very curious to see people using the TECHART/DEO Saker Falcon Lite.
