Fitting a Photomic FTN finder to an earlier F

[peter_schauss2]

<p>I have an F, serial # 687xxxx with a TN Photomic prism on it. I found an FTN prism for a good price and would like to use it on my F. It works, but is a rather loose fit. The Cameraquest site says that I need to replace the name plate on the body so that the clamps on the front of the prism will latch properly. What is the difference between the early and late F name plates and there any other problems I would encounter trying to fit the FTN prism to my camera?</p>

<p>Back in the day, I had two Nikon F's. One was a '68 with std. prism and the other a '72 with the FTn meter prism. On the '72 the lower corners were milled out so the clamping pin could secure it. If you notice the small lever on the front of the FTn prism will flex the lower clamping pins in and out. So when you slide the FTn prism on the spring loaded pins just clamped on to the lower nameplate, and to remove it you pushed in the small lever on the front, along with pushing the button on the rear of the body to release the prism. I'm not sure, but there might have been some differences on the side of the nameplate also. You definitely have to replace the name plate for the FTn prism to mount on a '68 F body.</p>

<p>I hope this helps,<br>

The "69" block starts the newer style nameplate for the Ftn finder. They are easily replaced once you get the new part.
