Voigtlander E lenses on Sony cameras

I'm struggling to google this information about the native Sony (non-Leica) Voigtlander lenses, does anyone know? Am I correct in the following statements:
  • You focus at wide open aperture, the lens automatically stops down when the shutter is clicked
  • Shutter priority is not available
  • Focus shift could be a problem, depending on the lens formula
  • Aperture info goes into the EXIF

Thanks for any info/insight.

They're fairly new, so not many people, I'd bet. I'm curious about these things, too. I don't think they have automatic aperture, though—I think you focus at taking aperture. The decent EVFs on the A7 cameras should compensate adequately, though.

Unless you are referring to an automatic lens I am not familiar with, all V lenses are manual focus and aperture setting. Please provide the exact lens you are asking about.

Have look here - this team uses mainly manual focus lenses with Sony A7 series, including some CV E lenses

As mabelsound says they are all manual focus and manual aperture lenses and so Apeture Priority shooting is just fine (and yes you can focus at any shooting aperture) - the CV E lenses have electronic contacts for EXIF data

I just imagined that they were manual focus lenses Simon
I use my Leica lenses on my Sony cameras and focus at the taking aperture
Makes no difference to the EVF.
I use shutter priority for sports shots with the manually set aperture and it compensates with the ISO
Very flexible
It's a better solution than when I use a lens like the Canon 70-200 because the camera recognises the lens and ,if I'm on shutter priority ,it will open the lens rather than increase the ISO
Obviously it can't do that with a manual lens and as they have bags of ISO headroom an increase in the ISO is the preferred option


Focus shift is never a problem

disclaimer: I don't own any of the Voigtlaender E mount lenses and can't say for sure

- concerning auto exposure I strongly believe that they work just like any other manual lens adapted to a Sony E mount camera.
Focus and aperture are set on the lens. Aperture mode working fine.

And I believe that Phillip Reeves statement that S mode and P mode won't work are partly incorrect, at least if the camera really behaves as with adapted manual lenses:
P mode will act as if in A mode and auto-exposes correctly.
S mode works, camera will auto expose if auto ISO is enabled: Aperture is chosen on the lens, shutter speed via wheel on camera, camera chooses correct ISO to auto expose.
( though of course, with much light during and a fast aperture, S mode, with a shutter speed that is not fast enough, camera can't go lower than lowest ISO and overexposure. )

edit: did some googling:
yes, EXIF goes to the camera, see: https://www.dpreview.com/news/496223...primes?slide=3
another difference to adapted manual lenses: if set so on the camera, the camera automatically engages magnification when focusing ( as with Sony E mount lenes when set to manual focus ): https://voigtlaender.com/e-mount.html
focus shift indeed seems to be a problem: https://admiringlight.com/blog/revie...sic-e-mount/3/
can't get conclusive information if the camera stops down the lens at release

-no auto aperture.
-no shutter priority (closest thing is AUTO ISO in manual).
-focus shift could be a potential issue if you focus wide open, then stop down the aperture without re-checking the focus in EVF/LCD.
-aperture and focus distance are sent via the CPU in the lens to camera EXIF data.
-additionally, focusing the E-mount lenses auto-triggers the "manual focus zoom" feature if you so desire it.
