Tetsu Iida's Leica Lens Class

Ten Leica lenses, taught as a class: history, optics, and what each one does to a picture — with the photographer's own sample images.

The lecture room

• Introduction — Leica and I
• History — Leica cameras and their lenses
• Optics — what each lens does, shown in photographs
• Supplementary class — Leica accessories
• After school — my three best Leica lenses, current and vintage

The reference room

A chronology and a family tree, placing each of the ten lenses in context.
