Want to Buy WTB Rear cap for Nikkor Enlarger Lens

Hi,

I have a Nikon Nikkor 50mm enlarger lens that I'd like to buy a rear cap for. From what I can tell, the rear threads are 39mm?

I bought a cap on ebay that seems to be 39mm, but it doesn't fit. Maybe someone has an extra that they'd be willing to sell?

Thanks,
Brad

Nikon didn't make rear lens caps for enlarging lenses; Leica made metal silver ones but $$$$

Any 39mm cap with a Leica thread will fit, not necessarily from a Leica - Fed lenses have 39mm rear caps so a dealer may have an odd one lying around

You may also need a cap that is deeper than a standard Leica lens to accommodate projecting rear elements.

Well, this is what I bought off of ebay last week:

It must not have been deep enough, because it didn't work.

Sent you a pm

Didn't they make a plastic case for their enlarger lens, similar to what Hasselblad has for their camera lenses?

Yes they did - they came with one when new

Instead of caps, I just bought some 4x4x2 white boxes from a local shipping store and store the lens and the lensboard (with some silica gel) in the box. I have a pair of Beseler enlargers and these boxes protect my lenses from dust and scratches, and keep them attached to the lens board for easy swapping. None of the glass elements of any of my enlarging lenses extend beyond the barrels that surround them, so they never come into contact with the top or bottom of the box. And since the box and the lens board fit so snuggly together, they don't rattle around.
