Somewhere along the lines, my Calumet Caltar-S II 210mm f5.6 lens lost the aperture scale, and so I have to guess what I'm setting it at. I guess it was held on with two tiny screws? Does anyone have the same lens that they can temporarily remove the piece from and scan it at 300 dpi? Then I could take that file and print it out and tape/adhere it to my lens...

I used to be able to rough it in and then "polaroid" my way to a perfect exposure, but that isn't so easy these days.

You mean they both got lost? The one on the top and the one on the bottom front? And don't you have a blank scale that is held down by the two screws? If so, any camera service person can calibrate them for you.

You could calibrate them with a digital camera.

Nope, both gone. Sucks, doesn't it? Yes, it does.

So you have a lens that someone remounted into a shutter?

My local office supply store did not carry the Brother p-touch 'white on black' tape, so I had to order it.

It came yesterday and here is the f-stop scale I made with it.

Seemed to come out nearly perfect with this sequence:

5.6[space]8[space]1116[space]22[space]32[space]45[space]64 (notice no space between 11 and 16)

Font: Helinski
Size: 12

wow, cool!!! I'll try it!

There are little tiny screw holes on top and bottom, and it looks like someone removed the scales. I think it is the original shutter, just missing the plates that held the aperture scales.

Sounds more like a used lens that was put in a used shutter that had scales that were wrong for the lens. If that is the case the spacing of the cells may be incorrect and shims may be needed or not needed depending on the specific lens/shutter combination. The lens should be checked by a qualified service person if this is the case.
