It is absolutely possible to use a p2 with a digital back, in 3 different ways:
1. with the lenses on DB mount and Sinarcam 2: the Cam2 is not longer in production, however and sometimes we do have refurbished ones.
2. with the lenses in DB mount with the "Behind-the-Lens" Copal shutter: in this case the multishot function (if needed) has to be done with darkened studio and shutter on B, trigered from the computer. Single shot can be done "normaly".
3. with the lenses in Copal mount: same as above, multishot needs darkened studio. Single shot can be done "normaly".
Those 3 configurations can be used 2 different ways:
- with a "Carrier Frame" positioning the back exactly in the focus/image plane to be able to make use of the p2's easy 2-points sharpness plane adjustment (tilt/swing) and with even a "Revolving Adapter" if wished (no need to take away the back from Vertical to Horizontal shooting).
- with a Sliding Adapter 100 and "Tapered Bellow".
In fact, photographers starting with digital backs on a view camera have all used their existing Sinar p2, usually with the Cam 2, and there are STILL many using this configuration. If your p2 is in good condition and the movements/gears well adjusted, then it is absolutely easy and without any probem at all and the mechanisms are precise enough. There is even a special "Depth-of-Field" scale you can mount on your p2, taking in account the size of the sensor for your f-stop calculation.
I have myself worked for years with these configurations above, untl the p3 became available.
IN ADDITION: I would not and never get rid of my p2 camera: you have the possibility also to CONVERT it to a Sinar p3 (re-design of the p2 for digital = smaller, shorter shift ways, lighter, ...) at very low costs: this conversion kit consists of the 2 4x5" frames (lens and image) which are exchanged with 2 100mm p3 frames and with in addition a 100mm p3 bellows. Once the conversion is done you have the possibility to work with different lens mounts (CPL mount = Coal, CMV mount = Cental Magnetic Shutter) and CAB mount = full automatic control via Captureshop).
Digital lenses from 28mm up to 210 mm can be used.
I hope this answers your questions.
At one time, I thought you could use digital backs with my Sinar P2. Then I heard that the rack and pinion mechanism was not fine enough to use them with. Could the gentleman, from Sinar, who posts to this board clarify that for me please? If someone else has any recent experience with the newest backs and Sinar, could you add your experience as well?
Also, can I use the 24 and 28 digital lenses with the Sinar p2 camera as well?
