I've been slowly working on selling off most of my hoarded equipment/good deals I didn't need.

I found one of these items in (one) of my camera bins. It's a plain white box, 150mm tube with LTM on each end.

What would this have been used for? Macro with a 400/800mm lens?

I found an old Canon product guide from 1965. Canon made several extensions tubes of all sizes for copy stand use (from 25mm to 200mm). I guess any number of lenses could be used on them.

You could take a generic LTM body cap and fit a pinhole lens to it for fun. 150mm focal length "lens" with extraordinary depth of field...

Thank you both for your input. I don't see myself needing ultra close ups and I'm not much of a pinhole fan so I'll likely move this along.
