With the Universalis you can have a sliding back, you can't on the Actus, so I don't think the Actus is a good option for CCD backs.You should be aware that any of the CCD backs are a real PITA to use with a Universalis/Actus. I have practiced with my IQ180 and finally gave up and ONLY use my Leaf Credo 50 which is just as easy to manually focus as a Nikon or Sony DSLR using live view.
You sure will throw out the sliding back. But..... even with this gorgeous live view with longer lenses (120mm, 150mm, 180mm) focus is very critical.... its very easy to be a smidgen far or near so I still check the image afterwords.As soon as I get CMOS live view I will throw out the sliding back, but meanwhile with CCDs I think it's a "good enough" solution, and I do focus the SK35 from time to time.
The Arca-Swiss Canon lens board allows electronic control of the aperture of a Canon lens on either a 110/Universalis lensboard, or any 6x9 front Arca-Swiss camera. It also will not only set the aperture, but open shutter wide, then stop down with a push of a button to the shooting aperture. There will also be a board for RM3di/RL3di MF cameras, abit later in the Spring.Hi,
Does anybody know what the latest is regarding lenses that can be used on the Arca Swiss Universalis?
Thanks
You are correct. I mistakenly wrote 60 for FFD, and it should have been 67.3 yielding a clearance of 26.40 and therefore would work fine as you found in use.Hi Rod.
Great note.
One question. On the 60 XL Schneider F 5.6 your note says it won't work. I used the 60 XL With the Arca DSLR2 and Sony A7R with no problems. 60 XL in R mount. When you say won't work do you mean with the Universalis? Just curious why this lens won't work with the Universalis/Sony when it's fine with the DSLR2 or M2.
Thanks

Rod, could you please explain how the focal plane shutter will work on multishot mode with (say) Sinar 6.1.2 software? What the hardware selection should be for one to have the software to recognize the set up?The Focal Plane shutter with DEX controller, is coming soon. We are hopeful for first deliveries in December, or January at the latest.

I have a different proposal than using a sliding back at all with CCD backs that should also work very well with other backs than the Contax 645 backs I use...With the Universalis you can have a sliding back, you can't on the Actus, so I don't think the Actus is a good option for CCD backs.
With a sliding back it's fine, but you need to compose and focus on the ground glass which indeed can be tough, especially with SK35. In my Linhof Techno review here: Review: Linhof Techno I discuss ground glass focusing at length if anyone's interested.
I've only used Linhof sliding backs, but from what I've heard from other users and my own analysis I think that the Kapture Group sliding back is a better buy than the A/S native sliding back, first because Kapture Group's is significantly cheaper of course, but it also seems that the Maxwell Optics ground glass with integrated fresnel does wide angles like the SK35 better (=less bad) than Arca Swiss own ground glass.
As soon as I get CMOS live view I will throw out the sliding back, but meanwhile with CCDs I think it's a "good enough" solution, and I do focus the SK35 from time to time.
It seems like "NoBob" is more interested in using it with a Sony A7r though, so I guess it doesn't apply.
There is a (DIY) way in working around this, but one has to sacrifice a Contax 645 body and it includes some personal involvement and some (basic) skills... The solution is applicable to many view cameras that have the ability to have their lens mount plate on the front standard to come real close to the rear standard.Also, do you consider a Contax 645 lens board now that the Eos board is ready and the interface is similar?
I would also be very interested in such an adapter as have seen some very encouraging samples of these lenses, both in terms of large image circle and sharpness.. Just need a way to control the aperture!
Any prospect of this happening with the Universalis?
The shutter is self-cocking and will have bracket abilities as well.Rod, could you please explain how the focal plane shutter will work on multishot mode with (say) Sinar 6.1.2 software? What the hardware selection should be for one to have the software to recognize the set up?

And another question, do you consider adapters with mirrorless mount that will plug directly on the same hinges as MFDBs do, so that one may be able to simply detach the MFDB and attach the mirrorless on?
Thanks,
Hi, thanks for the reply, what if the adapter would have a slight conical shape towards the mirrorless mount? This should take care of the possible vignetting... I insist on this because it is important for some pros to just detach one and plug the other in between the same project... You may as well consider making such an adapter with a warning that some lenses won't do...We do not feel that a plate adapter works well as it introduces mechanical vignetting with the tube required to mount the body. The body also usually has a grip which protrudes forward, further increasing the length of the tube and therefore Mechanical vignetting. For example, the grip on an A7RII is deeper then that of the A7R...
Hope this helps.
