Lens Genealogy … Super Geeky

Over on the Lensrentals.com site, Roger Cicala has posted a pair of super-geeky pieces on the history of lens designs. The first one looks at three of the six primary lens designs out there – the Petzval Portrait, the Rapid Rectilinear and the Double Gauss.

Part two looks at the other three lens types – the Cooke Triplet, the Telephoto and the Reverse Telephoto.

Fascinating stuff … tempted to send this to my students and tell them there will be a quiz on Monday …
