A Bit on Lens Design
One of the side-effects of just how everyday and universal digital photography has become is that we tend to take lenses for granted. We fail to be astonished either by the pure science that produces great lenses or by the alchemy that produces beautiful images out of thin air.
In this fascinating 35-minute conversation photographer and blogger Matt Granger (also known as That Nikon Guy) discusses the finer details of lens design with Zeiss lens expert Dr Hubert Nasse. Although the video is not for the faint-hearted, Dr Nasse explains several basic scientific issues that influence practical lens design in a way accesssible to even non-scientists.
Ever wondered why 50mm prime lenses tend to be small? (I have, just like Matt.) Want to know in simple terms about colour dispersion, refraction and lens coatings? Do you want to hear what makes the 85mm, f/1.4 Otus lens so special? Sit back and enjoy the show!
