This is a report about a number of legendary lenses, which I happen to own or could lend from a friend („phothograf“), most of them being milestones of optical engineering in their respective design-periods. This is a report about SLR-lenses for 35mm-still-foto-cameras with focal lengths (FL) between 23mm and 25mm. Several designers came out with this optical principle within three years – with Pierre Angénieux earning the honours of being FIRST (in time and quality – 1950, 35mm f/2.5) in this disciplin. For the SLR-camera-user this age started with the appearance of the retrofocus lenses in the 1950s. What was the real improvement in SLR-wideangle-lenses since the invention of the retrofocus principle over the last 65 years? Does my personal judgement from analog-film-days which lead to the definition of „legendary optics“ – which I kept in my lens-portefolio over that time – correlate with objective resolution-measurements? Here are my findings.Īctualisation: Im my first published version there was an error regarding the year of appearance of the Topcor 2,5cm-lens, which was communicated to me by a reader: thank you: it’s 1965 instead of 1959! But this difference does not change anything in my findings and conclusions …Ģ4mm focal length is a real milestone in spreading the field of the view in wideangle lenses, coming down from FL 35mm over 28mm.
