    Zeiss Ikon Super Ikonta C (530/2) Compur Rapid/Tessar f4.5, "demo"

    I certainly don't shoot this 1934 camera for the sharpness. It's a great camera, but well, 1934 Tessar, uncoated.... sharpness ? huhu..

    huhu ?

    Think again...

    I just got a slap in the face this afternoon when scanning a TMax 100.

    First is the image, resized from 8080 x 5165 (or "40 megapixels") next are the "crop" of the original...

    Yup.

    I'm not surprised. I've got one, too, though mine is 1950's era so prolly has coated lenses and such.

    But still - when I get focus and exposure right, it does very well.

    Not so good for closeups - then an old TLR is better. But for anything else, it's great.

    The old uncoated Tessar is one of the sharpest lenses I've encountered on the 6x9 cameras. Your results are very close to mine.

    Hey, hey, hey, Let's not let that cat out of the bag. Now that you know I guess you have to find someone local to show you the secret handshake.

    I love my 1929 Ikon 555!

    I seem to find the uncoated tessar a bit too contrasy on mine, however.

    You can't beat that for sharpness.
    I have a Novar on my 6x9 and while not as sharp as yours, it's still pretty amazing.

    That's a new one - most people seem to believe that old uncoated lenses are weak on contrast. Maybe you should develop the films a bit less?

    I'm not at all surprised by the sharpness, though. I use Tessar (and Tessar-type lenses) on all formats from 35mm to 30x40cm, focal lengths from 50mm to 500mm, ages spanning a full century. They are ALL bitingly sharp!

    Some of you may be interested in THIS:

    I had no clue that there was a 75/2.8 Ikonta. If someone could clue me in I'd be much appreciative.
    No idea what's going to happen next, but I'm hoping it involves being wrist deep in chemicals come the weekend.

    Tessars were designed for f4.5 really; f3.5 was already stretching it a bit and I find that f2.8 makes it more or less useless at that aperture...

    I dunno...If I had the money I'd buy the camera to check it out, but I don't.
