    Help Identifying Lenses

    Snagged these 3 massive lenses at a garage sale over the weekend. Can't find anything about them online. They look military? Raptars, 6", 12" and 24" 4 1/2" X 4 1/2"

    Likely the big one at least is an aerial lens. Probably all 3. Better pics would help. Looks like one has a speed graphic board attached already.

    Sorry about the pic. Here's a better one. Yeah, I thought maybe aerial or reconnaissance, but couldn't find a reference to a 4 1/2" camera?

    The olive drab paint color might be a hint?

    What's the matter, Greg? Each lens is engraved with its name, focal length and maximum aperture. Maker, too. Can't you read? And can't you take a picture that contains this information?

    Why the anger toward the OP?

    Dan, I think he just doesn't understand what he is reading. He thinks the 4 1/2" lens is for a 4 1/2" camera and not the focal length of the lens.

    Except that two of the lenses are clearly marked 4 1/2" x 4 1/2"; apparently for a 5" rollfilm camera?

    To clarify, the focal lengths are 6", 12" and 24". referring to the 4 1/2" sq as it states on the lenses, I was referring to the film format of the camera. I didn't see any aerial cameras listed in google results in 5"? just 9" and 2.5" So curious if I'd found something more unusual??? or so mundane not even google cares.
    Might be fun to build a quick sliding box plywood 4 x 5 camera to use these with...

    Sure glad there is the "ignore list" feature.
