A customer of mine, Richard Gale, has come up with a fantastic solution to fit his A7R to his Rollei X-Act2 technical camera that I thought I'd share with all of you.    He's come up with a nicely fabricated package that allows the A7R sensor to be in the same position as the film plane would be if using the Rollei panshot adapter.  Here you can see some pics of his set-up:  Rollei X-ACT2 - a set on Flickr   btw - Mr. Gale has more than a little bit of design and fabrication experience WRT optics - he runs a company that makes unique lenses for cinema cameras http://www.dogschidtoptiks.co.uk

We've e-mailed about making a short run of these adapters - and he thinks he might be able to do so for an estimated $325 - if anyone is interested please get in touch.

The first thing to know is that there are two possible battery configurations for these cameras:  1) Rolleiflex or Sinar style batteries, and 2) the Leaf Style batteries.   The cameras come standard with the Rolleiflex type contacts in the battery compartment in the grip arm, however they can be ordered with the Leaf style battery contacts in the grip arm on request.
