  1. The film in Rolllei A110 is propelled forward by four springs

    at the back door of A110.

     

    I find that the film does not advance smoothy.

    I use a small screw driver to pry out the four springs a little.

    After doing this the film advances more smoothly.

  2. How to set film speed on Contax T

     

    Locate the ASA window on Contax T (it is on the left hand side of the camera)

    Press down the little button at the right side of ASA window

    Then turn the ASA setting dial on top of the ASA window, until

    the correct ASA number shows up in the ASA window

  3. conrad_hoffman, wrote 16X, ha! Not happening.

     

    Actually 300x already achieved 300x, 16x is a piece of cake

     

    You can look up old issue of American photograpy:

     

     

     

    Philip Priedell in in 1946 November issue of American Photography.

    Friedell used a two bath developer containing Benzotriazole.

    He use Dupont sound track film with very low film speed--Weston 8

    to take picture with this low speed film and developed in his two bath

    developer, he got result equivalent to Weston 300 to Weston 460

    a amazing speed boost of 300x to 450 x

  4. In a 1952 book "Introduction to Photography" by Tai Huai Ching, published in Sin Chew Weekly magazone in Singapore. listed a speed boost developer described by Philip Priedell in in 1946 November issue of American Photography.

     

    Friedell used a two bath developer containing Benzotriazole.

    He use Dupont sound track film with very low film speed--Weston 8

    to take picture with this low speed film and developed in his two bath

    developer, he got result equivalent to Weston 300 to Weston 460

    a amazing speed boost of 300x to 450 x

     

    I need to do my own experiment with 16mm Agfa Copex (ASA 16-25)

    in Pentax Auto 110 camera or EDIXA M16 cameras to see what speed boost I can get.

    Unlike Swerl, the chemical benzoletriazole is

    available.

  5. My Rollei A110 is black anodized aluminium, it has "Made in Germany" at the back door

    It needs a px27 6v battery

     

    The lens is focused by a slider, with pictorial signs to indicate close by

    objects or distant objects.

     

    IMO, Rollei A110 is most beautiful 110 camera

     

    My Minox 110 camera is too big

     

    Pentax A110 is cute, but not as small as Rollei A110

     

    10 years ago, I had a Rollei E110 in silver color, it is a simplified version of Rollei A110.

     

    The Rollei A110 sets both the aperture and shutter speed automatically, while the E110

     

    needs manual set aperture, and E110 sets only the shutter speed.

     

    Certainly Rollei A110 is simpler to use
