Developers’ Interview for Canon RF 85mm f/1.2L USM Lens
Canon has published an interview with the developers of the new Canon RF 85mm f/1.2L USM Lens. In the interview, the developers answer 10 questions about the various aspects of the design of the Canon RF 85mm 1.2L USM.
Below are some questions and answers from the interview:
How is the bokeh different from that of its EF-mount cousin?
Kaishi: “In terms of bokeh, a key point is that the minimum focusing distance is closer than that of the Canon EF 85mm f/1.2L II USM. The strong bokeh created by f/1.2 can be used to create new types of imaging expressions such as close-ups of areas decorated with jewels.”
How sharp is the lens, really?
Kaishi: “When we were developing this lens, many performance tests were carried out repeatedly on a prototype. When shooting at the widest aperture setting using Eye Detection AF in portrait photography, our test photographers spontaneously let out cries of excitement when they saw how sharp the photos were.
How have you included a wide maximum aperture of f/1.2 while keeping colour fringing at bay?
Kaishi: “I sometimes shoot weddings, and I have always felt that colour fringing on white clothing does not represent what people really want in a portrait on such a special day. So with this in mind, we decided to utilise the greater freedom in design made possible by the RF mount.”
