    Re: Fujinon 1200mm F24 Lens Found!!!

    Haha, I guess that's why they marked apertures down to 128 (as someone said before, not 90 like they were going to) AND it moves much farther down, looks like enough room to go to 256 actually.

    Thank you Dan and everyone!

    Let's see what this 20x24 Scovill Portrait Climax can do. With its 6ft bellows draw things should be pretty interesting.

    The only other lens I've seen that does that is Zeiss Tele-Tubus. My guess id that angle cuts are more precise and also don't slip at all.
