    Re: getting glass CLEAN, how do you do it?

  5. Re: Helicoid for Fujinon 65mm 5.6 on Linhof Technika

    The 4X5 Super Technika cameras can cam couple to 75mm lenses and no wide angle focusing device is needed. Linhof stated that the shortest lens that could cam couple and focus on the tracks was 75mm....

    Re: 4x5 Portrait lens & Chamonix F2

    Your camera does not have a very long bellows and for portraits you don't need a lot of covering power, so consider a telephoto in the 240mm to 270mm range. Some are both quite sharp and quite...
