[Leica] Elmaron 60mm f/2.8 in a Helicoid Focusing mount?

Not enlarging lens - projecting lens, like for throwing slides across the 
room against a screen.

Thanks guys! It's just that with all of the posts I've seen in other forums 
about using lenses like these for macro work, I was wondering if it would 
work for me. Given how low the price is, I'm tempted to get the lens anyway. 
So what's the real thread size of the enlarging lenses from Leica? I thought 
everyone used the M39 as the mounting standard.

Additionally, you should know that I'm using this lens *on a digital CCTV 
camera with a 1/3" chip*. I think that combination will wind up only using 
the center of the lens' projected image. So if there was a concern about 
uniform sharpness or illumination across a 35mm frame, that doesn't apply 
here.

Thanks again,
