    Was looking for the Pentax and Elitar 25mm f/1.4 lenses on ebay and stumbled upon these:

    25mm from johnjqx (US)

    and

    25mm from shortfin-trading (HK)

    Bought one from the HK dealer. Not really setting high expectations but I'm hoping at least to get something usable :) Thought some of you might be interested.

    Will be posting sample images once I get my hands on this.

    Thanks, yes please post some results when you get it. I've seen those lenses floating around for the past few weeks - when I asked the seller what make they were, he just said "3rd party"! I'm usually totally toasted after 2 parties, let alone 3, so I can well understand his vagueness.

    Who says that the "Angel [sic] of view" is "14°24′". Assuming that he means "angle of view", wouldn't this imply a tiny image circle? (I note that neither dealer seems to mention the image circle.)

    Lens arrived today. Will go and pick up an adapter later and hopefully post pics later. This thing is quite heavy and solidly built. Can't wait!

    Here are some photos of the lens. It's around 2 inches in length, and 1.3 inches in diameter.

    I'd say that the quality is okay. I think the barrel is made of metal and it's quite heavy for its size. I didn't expect to get something like this for $29. Will post more later once I get an adapter for it.

    i got one of these with the adapter, and i wish the aperture was the ring that was closer to the camera instead of the focus. its hard to focus this lens, without accidentally turning the aperture ring, especially with the focus ring being so stiff. i think it needs some sort of modification, being so cheap i don't mind to mess with it, i will post later if i am successful in doing so.

    Mine finally arrived!! Very odd lens with major vignette and serious edge distortion!!! Quite sharp in the center though. There is no way of knowing that aperture you have set as there's no markings. Will be a good lens for abstract stuff.

    I ordered the 35mm and the aperture is the one closest
    to the cam. I'm waiting for the new c-mount adapter with
    the wider throat......

    My lens arrived last week, but i had to wait another week for an adaptor (bought from a different source) to arrive before I could try it out.

    Intriguing lens - vignettes a lot, with the vignette getting harder as you stop down. A bit soft wide open, with a weird kind of swirly bokeh - like the edges of the image have spun a little.

    A few more in the gallery, the rest in a flickr set here.

    I bought both the 25 and the 35, and I love the 35 for its build quality and all that, 25 is kind of disappointing.
