A7R + Canon EF lenses. Novoflex or Metabones III ?

I am interested in buying a A7R and using it with Canon EF lenses.

I understand that the Metabones allows AF but I have read that it doesn't work that well and requires mods to reduce reflections.

Is it better to just go with a "dumb" Novoflex adaptor and plan on Manual AF?

Any insights greatly appreciated.

Re: A7R + Canon EF lenses. Novoflex or Metabones III ?

I have A7 , Metabones III and Canon EF lenses.  Mine works just fine with the EF lenses.  AF is slow but does work with certain EF lenses.  Be sure to check out Metabones web site for AF compatible lenses.  I still use MF on them anyway as MF is incredibly easy to use with focus peaking.

I have no other issues and not sure what you are referring to on mods.  I don't have experience with Novaflex but here good things.

If you don't need AF and in most situations it will be rather slow, the biggest advantage of Metabones is that you can control aperture from camera. With Novoflex, you won't be able to set the aperture, unless you use Canon EOS body to preset it (by holding DOF priview button, while removing lens).

On the other hand, there are several alternatives to Metabones, usually much cheapper and according to user reviews - as good if not better than Metabones. My problem with Metabones SA III is the infinity focus with Zeiss ZE lenses (just can't reach it) and difficult service logistic including firmware update.

I am not really interested in having to set aperture that way so I will go with the Metabones unless you can name a better adaptor.

Thanks for the response.

Re: A7R + Canon EF lenses. Novoflex or Metabones III ?

As someone else noted, aperture control is the gotcha with Novoflex.  Until they come out with a solution that at the minimum gives you the ability to set aperture, you're probably better off with the Metabones adapter.

Focus works well on the Metabones, but it's slow....at least on my lenses.  I have not had issues with reflections, but I don't shoot TS-E lenses which seem most prone to causing the reflection issue.  I used this on my adapter, just as a precaution.

Can't say it made any difference, but I guess I feel better.

Re: A7R + Canon EF lenses. Novoflex or Metabones III ?

I am using the A7 with MBIII mainly with 24, 28, 35 image stabilized primes and the 17-40, oh and occasionally 100/2 and the EF-s lens 60 macro.

I do sometimes use the 24-105 and other zooms, but they balance better on my Canon bodies.

For my use, the exif info, the image stabilization, and the AF, although slow are the reason I got an A7 in the first place.

I've read about taping the adapter but don't plan to do that as I see no need.

I'm not going to recommend anything except maybe going into a store and trying for yourself.

I tried the A7 without electronic first curtain and the MBIII was even slower and sometimes missed focus.

Re: Metabones III then…...

As I said, I am very happy with Metabones and my EF lenses . I do like Aperture control and as mentioned, MF is great with focus peaking.

Re: Thanks everybody; appreciate all responses given.

I have RJ's EOS to NEX Full Frame adapter on the way.

Autofocus plus ability to change aperture. US 289.

Will post a review once I receive it and test it with my Canon lenses

17-40, 50 1.4, 85 1.8, 70-200 4 L

BTW..These lenses are excellent on my A7R already(wide open for most shots) using

a 'dumb adapter'.

Re: Thanks everybody; appreciate all responses given.

I have the metabones 111 and it is slow. I have found it works accurately if I use the cheap wireless control from e-bay set to 2 seconds. so no good for street photography if people are moving. IS and AF work even on my 12 year old lenses which surprised me as there was only a guaranteee from 2006. Fredmiranda.com wrote an review of metabones with canon lenses so read his review.

Re: A7R + Canon EF lenses. Novoflex or Metabones III ?

there are some cheap adapters available from overseas now, that appear to have the necessary electrical connections that enable communication with the camera.

b&h has one, and there are other brand names listed here as well:

Yeah, I'd grow very tired of putting my 100/2.8L Macro lens on the A7 and going to shoot a macro shot and realizing I needed to change the aperture. Taking it off and placing it on my 6D and setting the aperture and then trying it on the A7 only to realize it's still not right. Repeat. No chance that would be part of my workflow. Spending extra for aperture control is well worth it to me.

Re: A7R + Canon EF lenses. Novoflex or Metabones III ?

Don't know about the Novoflex, but I recently rented the Metabones III with the Canon 8-15 F4L and it worked great for me.  AF works well, albeit a little slow as others have mentioned.  I mainly use my a7r for Landscape and CityScape work on a tripod so the AF speed is not an issue for me.  The only thing I would note, is that if you use any of the 1.2L Glass, the a7r only displays F1.3 as the a7r counts in 1/3s of a stop.

Much the same experience w/ an A7R.  I normally use the unit with manual focus and focus peaking; much faster than the unit's autofocus!

It works with both EF and EFS lenses.

I have tried several of the cheaper alternatives (3 at last count) and none of them have the snugness of fit and quality of the Metabones III.  Nothing like having the camera body and lens going different directions!
