I heard from one tech who admires the Blue Stars but doesn't want to spec them because of inadequate locking of the focus ring. I can see his point--it's rather easy to accidentally unlock it, not that you can't simply mark the setting in case that happens but a more secure lock might not be a bad idea. I do love mine.

I've had that problem with the Blue Iscos. I just put a discrete piece of splicing tape on to stop if from walking. Nice lenses those, they're not 'alf sharp!

I always run a ring of electrical tape around the focus ring to keep it from "accidentally" being moved.

I think the oldest magnacom I saw was in Green Bay, Wisconsin. It was about 8 inches long and looked like a Cinemascope attachment.

A Pacific Optical "Xpansa Lens", perhaps?

It's not the most efficient thing on the face of the earth, and the optics are marginal at best on this example. I'd much prefer a modern Magnacom over this beast, but, well, it served its purpose in its day.
