Hello everyone,

I saw a picture from LIFE magazine, those people hand held Speed Graphic machines with Quick Focus Lever accessories (see picture left hand side), never seen this mention in user guide or service manual.
Is this came from third party supplier? any information about this?

thanks in advance,

From the photos and the instruction book cover, it looks like a simple clamp-on device that mounts on the bed plate focus knob of the Speeds; the XL version would clamp on the lens focus ring. I wonder if either of these gadgets confers any advantage over nature's own thumb-and-forefinger device on the end of your hand
