Using Leica M and Nikon G lenses on the Sony A7 (How will it work question)

[jljohn]

I'm considering a Sony A7, and I am wondering two things. First, if I use Leica M lenses, how will it work? I will need a Leica M--Sony E adapter, and then I can use it as if it were in an aperture priority mode (i set the aperture on the lens, and the A7 meters and handles the shutter speed)? Or will it be completely manual?

Also, as I have a number of Nikon f/1.4 G lenses, I am curious if there is any way to use them on the A7. I am under the impression that I would not be able to set the aperture at anything other than the smallest aperture (i.e. f/16). Is this correct?

Thanks!

It meters through the lens, so in A mode it will select the shutter speed for you. If in S mode, you will have to set both the aperture and shutter speed.

As for the nikon, with the cheaper adapters the "G" series lenses cannot adjust aperture. The more expensive adapters, like metabones, has the ability to open and close the aperture.

Thanks? One additional question:

Is there any disadvantage with the Voigtlander Leica M to Sony E adapter versus the Novoflex?

For Nikkor G lenses the current state of support is pretty dismal. I'm not sure but I've heard theories about Nikon's AF system being harder to map to the NEX pins and control interface than Canon. If you have L lenses you can expect moderately fast contrast detection AF and in-body aperture controls.

As for m lenses, I tend to shoot them in S with auto ISO. I select an iso and shutter speed combination and then just focus and shoot.

There is no quality difference as far as I can tell. The Novoflex is made in Germany and the CV is made in Japan, that's all

All "G" adapters can control the aperture. But due to the way Nikon controls apertures, all of them, whether cheap or expensive, have to make do without an aperture number indexed aperture ring. The better ones have EV numbers printed on the aperture ring.

Only advantage really is if you go with sometihng like the Hawk's adapter which has a built in helicoid so you can close focus with your m-mount lenses. I also think Voigtlander is coming out with something similar:

Other than that, besides build quality, there isn't a noticeable difference between the adapters, at least ones that I have tried.

I think you can with Metabones adapter. Check youtube. I know I watched the guy from the Camera Store use a Canon lens.
I believe Sony is going to release some sort of app that will correct for Legacy lenses a correction for wide lenses.

Thanks for the replies so far. I have one further question--I was reading up on the Zeiss OTUS, and I see that the OTUS for Nikon has an aperture ring, whereas the OTUS for Canon does not. Yet, several reviewers, Steve Huff included, had tested the Canon OTUS on the A7/A7R via a basic adapter. How does that work? If the Canon Otus doesn't have an aperture ring, how is the aperture adjustment being made?

Here is a photo of the setup: http://www.stevehuffphoto.com/wp-content/uploads/2013/10/otus.jpg

The Metabones adapter that Steve was using to mount the Otus on the A7/A7R supports aperture control via the camera, the same way you would control a standard E-mount lens.

Thanks. It's a shame they don't seem to make a similar adapter for Nikon G. Everything I'm seeing uses a non-f-stop-specified dial on the adapter itself. It's amazing how complicated this is all getting with the number of manufacturers, systems, sensor sizes, adapters, and mechanical v. electronic controls there are out there! Now, if I could only make a Zeiss M lens work on a D3S!
