I see (2) VERY necessary items that Cambo will need to implement into their line of accessories for the Actus line:
1. Recessed lensboards(looking at this, I see this really only being able to work with enlarging lenses that do not have integrated shutters, or the same tech-camera lenses from Rodenstock and Schneider being mounted IN-BARREL, rather than in a factory mounted shutter(since the shutter is actually in the camera body).
2. "Top Hat" lensboards: These would allow longer amounts of extension than the stock camera utilizing flat boards will allow. So using shorter FL lenses such as 45mm/50mm APO Rodagons and or Schneider's APO Componon HM line(40mm, 45mm, 50mm, 80mm, 90mm, etc; or APO Macro-Digitars(again, in barrel(like an enlarging lens) or in-shutter).
Both are easily machined, and I can see them being offered in different sizes/depths for different uses. (10mm, 15mm, 25mm for instance)
just a thought, cuz I know I'd be getting some made for myself if I was getting one of these(which I'm not, but still)
