I use Rollei electronic shutters (Sironar Rodenstock Digital lenses) on my Rollei XAct2 and LEaf Aptus 65 digital back. I have no issues. I use a Rollei Lens controller. I capture my images to a CF card I have two manual lenses as well. The electronic shutters are very easy to use and there is great accuracy in reproducibility between shots. I am happy to answer any other specific questions. Mark
I have recently taken delivery of the Schneider Electronic shutter which I am going to be using with a Cambo Ultima and eMotion22. It did take a few months to arrive and there didn't seem to be a lot of familiarity with it by the distributors, but it does exist!
I was under the impression that the Eyelike Capture Pro software would operate the shutter remotely from the Mac, but I have now found out it does not support it with the e22. I'd guess that use with the Eyelike Precision range of DB's is supported in Capure Pro. Software development with Capture Pro has now stopped.
There is a software update (no release date) in the pipeline for Sinar Captureshop to support the shutter and it is also supposed to be supported in the new Sinar software I believe due in first Quarter of 2007.
At the moment, to be able to use it I understand that I'd need to buy the Schneider controller which enables you to use the shutter without a Mac.
I don't know if the P25 software supports the shutter, but the future looks OK for eMotion users.
Anyway, I can't give you feedback on using it ..yet.
The shutter does fit into the recessed lens board of Cambo Ultima23.
Hope this helps
