    This is a first as far as I know.

    A 35mm F2 lens in Contax RF mount. This lens was made originally in FASTAX mount, a bizarre 1950s bayonet mount for high-speed movie cameras.

    I took a J-12 in Contax mount that had some marred glass, took the optics module out, bored out the barrel, and cemented in the Raptar. It looks like it covers a full frame, using the through the lens viewer. I set the optics to agree with the RF of a Contax. I do not know of a Fast 35mm lens in Contax mount, although I shimmed a Nikkor 35/2.5 for a friend for his Contax.

    This lens renders much like a Canon 35/2 in Leica Mount.

    Not bad for a Junk lens, total of $25 including the J-12.

    I tried it on the M8, covered the full frame without vignetting. I'll try it on a Contax IIa next. Unlike a J-12, this lens does not extend past the Mount.

    Oh, man!
    1) Great to see you're still up to the usual optical shenanigans.
    2) What text is the lens sitting on in the first image?
    3) When I saw the Wolly name I had a mental image of an LF lens :) Be fun if I could adapt my Wolly 6.5/9.25/16" triple convertible somehow :eek:

    The book is "Photographic Lenses", Neblette, 1973. The 1965 edition has more block diagrams in it. A great resource.

    Cool. Thanks for the info, Brian. I just ordered a copy of the 1965 edition; it'll be nice to have as a reference.
