Nikon Back

I love doing new things that require a bit of planning. As previous posts show, I have started up photography again and been a bit successful with it. I recently had a photo chosen by the Torontoist to display on their site. If you want to see the photo go here.

Anyhow, that bit of news is not what I want to write about here. In browsing Flickr I discovered a Flickr friend had produced an image using a Canon 5DmkII mounted on a Widepan sliding back attached to a Linhof 4×5″ Technika V camera with a Wollensak 11.5″ lens (see the image here) . I loved the color the lens produced and I also was attracted to the challenge of doing the same thing using my Crown Graphic. I decided I would try to attach my Nikon D80 to the camera. The fun was in the planning.

I needed a mount for the camera and Stan, at International Camera (now closed) gave me an old Nikon lens that had the mount I needed. I took the lens apart and voila, I had the adaptor. My next problem was to decide how to mount the adaptor to the Crown Graphic. I let the problem sit for a few weeks and one morning woke up with the solution. I would go to the art store and pick up a foam board that I could cut to proper dimensions and mount the adaptor on. While looking at the foam boards I saw a 5×7 canvas that artists use to paint on. It was perfect, two glued together would be just the right thickness for the Graflox back on my Crown. I bought some flat black paint and three boards and the total came to $11.

I measured the film holders and applied the measurements to the canvas, cut the canvas, found the centre location for the adaptor and cut the required hole for it. Everything worked like a charm. Actually, I was going to mount the adaptor with the lens barrel but decided to use an extension tube as a spacer for the camera and mount the adaptor fluch on the back. Here is the pre paint (I need to paint the Nikon back black) results……………

Initially I mounted the camera using a 36mm extension tube for a spacer but I couldn’t focus the camera to infinity. I stopped down the lens to f32 and this photo resulted……….

This was my very first picture using the Nikon on my Crown Graphic. Although totally out of focus I was really happy about it.

I exchanged the 36mm tube with a 20 mm one and these are the shots I took with it……….

All the above shots were with the focus on infinity so I had to test a macro shot using the same setup.

Since the Graflex uses bellows there was no reason why I couldn’t get as close as I wanted to my subject. Anyhow, the results of a closeup………………….

The lens on my Crown Graphic is Schneider Kreuznach Xenar 135 mm, a “normal” lens for 4×5. I don’t know what the focal length is when my Nikon is mounted on it but I suspect it must be around 500 or 600 mm. It was a fun project and now I need to find another one. Hmmm, maybe build a camera using an old Minolta zoom lens as a start.
