Help: Nicca 3-F w/ Nikkor 50 f/2 that will not fit?

PGraham3 · Oct 19, 2016

Howdy, Rangefinder Forum.

I picked up a sweet Nicca 3-F and I managed to get my hands on a clean Nikkor H.C. 50mm f/2, but it unfortunately doesn't fit. However, after examining the lens and doing some research, it appears that there is Voitlander adapter mounted on the lens. Not exactly sure. Am I correct? If yes, what would be the best way to get it off, as it appears it will not budge without some brute force?

I'm hoping to try out this sweet Nicca and Nikkor soon. Your help will be greatly appreciated. Thanks so much.

It should just unscrew. But something doesn't look right to me, like the adapter is broken. There is a slot for a spanner wrench on one side in the first photo, but no slot on the opposite side. Almost looks like someone snapped part of the adapter with a spanner. This makes me wonder if the adapter was cross threaded as it was put on the lens. I'd use brute force.

I've never used a spanner before, and from what I know there are different types, such as a face spanner, hook spanner, etc. Would a face spanner be normally used on something like this?
As it appears, I might just have to screw it off with some large pliers with 'brute force'. Just do not want to damage the lens threading.

It's also called a lens wrench by some: Link

You have been a great help, Kirks518! I found an image of a Voigtlander adapter, and it appears to be the same as the one mounted on my lens. Only one groove appears to be on the top. Makes me wonder how a lens wrench would work on an adapter like this. Any ideas?

This lens has an LTM-to-M mount adapter installed. Lets you mount this lens on any bayonet M-mount Leica body. Removal is the same whether it's Leica, Voigtlander or any other brand.

If the lens came with a rear cap that fits with this adapter installed (like the one shown above), just put the cap on, hold the lens in one hand with the rear cap facing you and turn the cap counter-clockwise.

As long as the adapter's not seized, it should break free easily and unscrew from the back of the lens. If you don't have a rear M-mount cap, you can try gripping it with a piece of rubber like a mouse pad.

Oh man! This is awesome! Thank you, jimjm! I will definitely try this with the rear lens cap when I get home in a few hours and let y'all know. Let's hope the adapter has not "seized". I'm quite impressed by everyone here on APUG, thanks a bunch!
This is actually my first LTM style of rangefinder, as I've mainly shot with SLR's and fixed-lens rangefinders. Thus, I'm definitely looking forward to getting this sweet camera and lens going.
