I've got the Aria body, so now would like to try the databack -- I'm intrigued by the idea of capturing each frame's exposure data. So if you have one you'd like to move on, please let me know.
After a couple of years without a reply, I'm giving this a bump. Actually, I'd also be curious to know if anyone here has ever actually used a D-9 databack, as they seem to be made of unobtainium.
