  3. Re: Thoughts About Nikkor SW 75mm F4.5 on Linhof Master Technika?

    Where are you guys getting your information about 4X5 Linhof Super and Master Technikas? Both can be easily cam-coupled to most 75s and used on the movable tracks? I first had a Super Technika IV...
  4. Re: Helicoid for Fujinon 65mm 5.6 on Linhof Technika

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

    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...

    I switched from HC110 which I had used since the late 60s to Ilford IlfoTec HC several years ago. I found the times at 1:31 and other dilutions were exactly the same as those I had derived for HC110.
