"Centering Aid" of the Sinar P-SLR system on a Canon 5D.

Curiosity can kill, if not frustrate along the way. I recently was tasked with shooting a white box on white, with full need for straight lines. While this would typically be a task for either tilt shift lenses on 35mm, or digital back on view camera. I decided to poke the proverbial sleeping bear and try out a system that I hadn't tried out in actual use.

All hooked up.

The Sinar PSLR system consists of parts of a Sinar P2 monorail camera, and parts that allow for attachment of either a Nikon or Canon SLR. In essence, you swap out the rear standard, and flip the front standard to allow for closer lens to image plane distance (and effectively put the shutter in front of the lens). The process took about an hour to get going (with the help of our Facilities Repair Tech, Mr. Bill Waldeikis), from sorting out which lenses would work, centering the DSLR camera, and ensuring proper Leaf shutter sync.

After breaking down the still life set, I pulled two friends passing by in to try out a few shots. White wall, PSLR with a drastic tilt, and a Profoto ProFocus on a D4 2400 pack, and bare head popped into the room for fill.
