I'm quite proud to announce, that my hybrid camera is finally complete!!! The base for it is Arca Swiss Classic 5x4 camera. I like this lightweight monorail camera very much. It's extremely flexible and well thought out systematic camera with plenty of movements. My problem with it was that I use old objectives without shutter on it. For some time I used "lens cap shutter" and neutral density filters of various densities, but was never really satisfied with the solution, as the shortest exposure time I was reliably able to pull was around one second. So after some thought I decide to use Sinar Copal behind the lens shutter. Its opening is big enough to be used behind barrel objectives that I have and exposure times from 1/60 to 8 seconds are enough for most situations. This means that front standard of Arca Swiss needed to be modified. The back bone of this modification was format frame of auxiliary standard from old Sinar Norma camera. Then a friend of mine made two aluminum blocks to connect it to rails of regular Arca Swiss front standard. Custom bellows from United Kingdom made new bellows for me and now it's ready for action. I tested the system and am very pleased with results.
