Stack Contax 645/EF and EF Smart/SL

I was wondering if anyone has tried stacking a EF Smart adapter for the SL with a Contax 645 Smart adapter for Canon and had any functionality on the SL. I don't care about AF, but aperture would be nice.

Interesting question. 

I have a Canon adapter for the SL and some Schneider-Kreuznach lenses for my PhaseOne XF. 
Can you provide a link to the Contax 645 adapter? Maybe I will buy one and check.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I have a JAS Contax 645/EF adapter and tested it with Novoflex Canon EF-lenses to Leica SL adapter.

 

Nothing worked.

 

No aperture info and no AF

 

Maybe there is a trick to do it.

Link below, but this is meant for Contax 645 mount, so the Phase/Schneider lenses will not work with it. I am curious though if there is another way to make that work because I have a nice collection of blue ring Schneiders with the XF also, and there are a few I wouldn't mind being able to use on the SL.

Thats too bad. I just ordered the Novoflex EF to SL and the Kippon Contax to EF, so I will test that out and see, but I feel like I will likely be returning those. It is too bad there isn't pass through functionality on the Leica Contax to S and S to SL adapters.

Today my Phase One dealer told me that for Schneider-Kreuznach there is no adapter available. What a pity.

You know there is a SL to S adapter and for the S there is the Leica S-Adapter C for Contax 645 lenses...

 

You can buy two Leica adapters and use them on your SL I'd guess.

When using the Leica S-Adapter, no mechanical or electrical functions, signals or data are transferred between Leica S-System cameras and lenses.

So there is no chance to set aperture on the S(L) with the adapter.

That is for the Hasselblad V, Pentax 67 and Mamiya 645 adapters...

 

The Contax 645 adapter (Leica S-Adapter C) made by Leica has electronics and does autofocus, exif, aperture etc. etc.

Same for the Leica S-Adapter H for Hasselblad H lenses.

 

 

See second pic in my article written about using Leica S with Contax 645 lenses with the above mentioned adapter.

I tried to stack those two adapters and the camera did not recognized them.

Maybe I am doing something wrong.

As far as I am aware none of the active adapters for the SL allow stacking with the exception of the M/SL adapter which can be stacked with R/M adapter. The EOS and S adapters don't allow stacking.

 

Remember these adapters have firmware to allow them to work and they're not set up for recognizing other adapters. The M adapter just reads codes.

You can use a "medium format" to EF and EF to SL adapter. But you will need a "stupid" EF to SL adapter, as the "intelligent" Novoflex AF adapter will not work properly (it will not display anything on the EVF during lifeview, but it will take a picture when the shutter is pressed).

So this is a purely mechanical connection (like using the M adapter). So the medium format lens must provide some sort of aperture control, or the mechanical "medium format" to EF adapter. E.g. fotodiox offers such adapters with a built-in mechanical iris. The problem is just that the iris is not in the optimal position.

There are even shift adapters (medium format to EOS).

 

Example: Rollei 6000 lens + fotodiox pro adapter (with iris) to EOS + "stupid" EOS to SL adapter + SL

Yes I have also read that the Leica S-Adapter C and H are not compatible with the Leica SL-Adapter S. Which is a shame because Leica could easily address this. 

 

That would mean people can then use Contax 645 and Hasselblad H lenses on their SL... For most lenses I would say it's a bit of a bull shit to use these medium format lenses on a fullframe camera except for a few:

 

Contax 645 Planar T* 1:2/80mm

Contax 645 Tele-Apotessar T* 1:4/350

 

And a handfull of Hasselblad H lenses which I don't really know very well.
