Re: [Rollei] Obsolete skills (was Why the 6-element lens for 3.5Fs)

As rollfim cameras (let alone view cameras) involve really getting into the
picture when compared with digital cameras, point & shoot cameras, and
automatic anything cameras, slide rules, when compared with pocket
calculators, involve really getting into the calculations and intimately
understanding them.

I've been sampling various slide rule sites on the Internet.  They were
invented and developed in Europe.  Keuffel and Esser, based in Hoboken, New
Jersey, brought them to American shores in the 30s.  K&E was the largest
producer.  They had numerous models with numerous variations.  My slide was
made between 1938 and 1944.  Pocket calculators, starting with the HP-35 in
1972, spelled death to slide rules.  They are still made, BTW, but not by

Now to give my slide its first cleaning now that I know how.
