Lens Mount

[TrevorBarnes]

Hello All,

When I purchased my red one about a year ago it came with a couple of different lens mounts. The only one I really cared about at the time was the Canon mount that was already installed from the previous owner. This might be a stupid question but can anyone help me identify what these other mounts are? Images attached. I am assuming one is the original PL mount and one is a nikon mount but I'm a little confused on what's what. Also are any of these mounts worth anything?

Thanks!

I maybe wrong but the last pic looks like a PL mount..

The one with the needle screw is the Nikon mount. The needle allows adjustment of the iris on lenses that don't have an iris ring.

The other two look like pieces of the pl mount.

Oh interesting. I never thought that needle was an adjustment for the iris. That's kinda interesting. Never owned Nikon lenses before so might need to look into that. Wish my Canon mount had something like that.

Also didn't realize that the pl mount was in two pieces, never used a pl lens before so I am just completely out of my wheel house on this.
