Removing a 21" Kodak Ektanon from a Prism
I just acquired a really nice Kodak 21 1/4" Ektanon that was shipped to me in a Kodak 3.5" prism.
The bottom of the barrel lens screws out and the bottom of the front element but not the front element.
Any experience out there as to what I need to do to in getting the front element out of the prism housing?
Thanks in advance!

For the record, I'd love a photo of this. Why is there a prism?
Warm solvent soak is my guess, but I don't know anything.

Post a pic on the Forum. Without seeing it,you’ll get lots of lame suggestions.

Large front prisms were common on process camera lenses. For example see this Wollensak catalog: http://www.cameraeccentric.com/html/...llensak_2.html
I think the main reason was to reverse the image so that it could then be used to make a correct image during reproduction (like the way that a woodblock for printing has to be in reverse).

On my 21" Kodak Ektanon there was a silver ring on the prism which rotated a few degrees and the lens pulled off. I sold the lens years ago but kept the prism. I never found use for it, but is beautifully made.

As per suggestions attached are images showing the prism with the last image showing the bottom section of the barrel with one section coming off of the top section of the lens. The remaining top section of the lens is what is locked in there. I have only tried to unscrew it with my hands to this point and it is not moving hence my decision to reach out.

Disregard my suggestion, your prism is different from mine.

Look around for any set screws.

Great suggestion Michael. It appears that there are some small screws on the exterior of the prism that may allow me to take out the outside transparent cover of the prism and possibly other segments. Then I may be able to get a flashlight to the inside of the prism to see if there are any screws holding this from the inside. Will report shortly. Thanks!
