  1. ABC plus pyro(Rollo pyro), which is formulated for use in rotary drums, is available from Photographer's Formulary and Bostick & Sullivan. I use in CPP-2 with expert drums (3005 & 3010). I also do ilfochrome, where the temperature control of the CPP-2 is important for consistency.
  2. This is a response by Dr. Fleisher to a similar post in the archives.

     

    "Contrary to popular belief not all lenses with the same focal length produce the same depth of field at the same aperture! A typical example is the Superachromat 5,6/250: It produces extreme sharpness

    (250 linepairs per millimeter)at the plane of best focus. But slightly off (which may be caused by photographer's focusing error, film position error, curvature of film, humidity, registration error of mirror or focusing screen, magazine wear, to name just a few), the sharpness drops dramatically. It can drop even below the levels the

    sharpness of a Sonnar 5,6/250, or the one of a Tele-Tessar 4/250. In other words: The performance of the Superachromat is extreme, but nervous. It requires advanced technique on the part of the photographer and also well aligned and maintained equipment, to actually utilize the full potential of this lens. Once all this comes

    together, the Superachromat shines. No other lens in the world ever gave me fine details with this clarity! This lens is perfection for perfectionists.

     

    Photographers who prefer to engage less with these aspects may even achieve "better" results with the normal Sonnar 5,6/250."

  3. Rod: Just to echo sentiments of above. I purchased G1348 from Robert White in January. Best price and great service! Received in New York within 48 hours of order. I'm 6ft tall and use G1348, 1370M head with Hasselblad and this past weekend with my Sinar F2(8lbs without lens). Thus far, extremely satisfied with performance. Alex
  4. If only I could remember my 50th birthday! I wear progressive lenses (modern bifocals). I recently purchased 503cw and replaced screen with Acute Matte D with split-image. I subsequently replaced Beattie screen in my 500c/m with Acute Matte D with split-image and also in my 500el/m. Huge improvement! I also find it easier to focus with WLF.
