Jay Allen - PS945 Observations
Cooke Portrait PS945 lens shown on the Series D Graflex camera.

I mounted the Cooke Portrait PS945 lens to the front of my Series D Graflex and it works like the lens was made for this camera. The Graflex D is the smallest Graflex 4 x 5 SLR that the lens will easily fit. When the camera is focused all the way back, the lens is at a perfect infinity focus.
Normally, the Series D Graflex will not take lenses with shutters because the lens mounting board fits inside the camera. The PS945 lens has a 9 inch focal length, so it can be mounted on the front of the camera by making a wood lens board that fits in the place of the camera's lens shade/front door. Here's how: Remove the old lens shade from the camera via four brass screws under the leather top and six or eight small screws on the side of the camera. Fabricate a wooden lens board to fit flush on the front of the camera. Cut a round hole into the wood to fit the new Cooke lens. Next, mount the lens board in place with four to six small wood flathead screws. Last, mount the shutter and the lens. (I also covered the lens board with black leather to match the camera.)
With the new Cooke lens, the Graflex D can be used in the studio for portraits because it now has an X sync shutter. There is no upside down image or need for a focusing cloth. The system can also be used outdoors because the camera has a focal plane shutter that runs to 1/1000 of a second. Use it hand held like a 35mm camera for quick shots. I shoot 4x5 and 2.25x3.25, 120 roll film. Close-ups are not a problem because the Series D has a lot of lens extension for this 9 inch lens.
