    Re: strange Componon 240 lens

    No, nothing but the bare bones of focal length and maximum aperture. Occasionally you will find out the shutter size/type for production lenses but the lists are basically when/what/how many/serial...

    Re: strange Componon 240 lens

    One of three prototypes ("Muster") assembled on 4/4/61 - along with 77.5 f4, 150/4.5, 180/4.5 and 300/4.5 versions as well for good measure.

    Re: Lens order on triple convertible

    The triple convertible Schneider Symmars had the longer focal length at the front as did the Angulons.

    Re: Graflex 1000 Specs

    Coincidentally, I recently purchased a set of Schneider Symmar cells that were made for the Graflex 1000 shutter. They are one of three sets of prototypes made in 1962 and are marked as 180/6 (not...

    Re: Komura/Komuranon 500mm f7

    I don't think they are convertible in the manner of an early Symmar where you remove one element, rather they have interchangeable elements like a Nikkor T 360/500/720
  9. Re: Angulon 18.5cm and 25cm combined lens in barrel

    I've got a catalog from 1931 which includes a table for converting Angulons. The 120mm Angulon has a 250mm front element and 185mm rear element so i guess that is your lens.

    Re: G Claron 355mm Shutter

  13. Re: When did Schneider stop producing Angulons?

    1969 appears to be the last year that all of the focal lengths were in production. There were four batches of the 65/6.8 in 1970 and a single batch of the 90/6.8. The last Angulon was a 65/6.8 ...

    Re: Strange COPAL 3

    It would certainly appear to be a Copal 3s which had a M56-0.75 internal thread (vs M58-0.75 for regular Copal 3). This is just fractionally larger than the Compound 3 (55.69 x 40 tpi) which would...

    Pere, the rear of the front cell of the 360/5.6 is only 54mm in diameter and the front of the rear cell is smaller again at 52mm, so a #4 shutter with a 52mm throat will not cause any mechanical...

    Re: Schneider 355/620mm Symmar Convertible

    No, the native shutter for the 360 Symmar is the Compound 4 which will give you f5.6. You don't gain any speed going to a number 5 shutter. There wasn't a smaller version of the Compur Electronic 5fs...

    Re: Using a G-Claron as a convertible lens?

    FWIW, and slightly off topic, I have the 1931 Schneider catalog which has a table showing the focal lengths and apertures of each cell of the Angulon, so being "convertible" was obviously seen as a...
