Canon Lens Designers Talk About Latest RF Mount Lenses in Interview
DPReview sat down with Canon lens designers (Manabu Kato – Head of EF + RF mount R&D, Yoichi Sato – EOS camera electronics R&D, Shogo Yamaguchi – Optical planning specialist).
The interview was about the new Canon EOS RP, the six RF lenses Canon is set to announce soon, and in general what’s going to happen with the EOS R system.
Excerpts from the interview:
How do you prioritize which [RF mount] lenses to develop?
So the idea for the initial four lenses was we wanted to deliver the surprise factor, so we decided to deliver the 28-70mm, as well as the 50mm F1.2, with stunning resolution. That was the concept behind these two lenses.
With 24-105mm we thought it would be the best match as a standard zoom lens to the EOS R camera, and the 35mm F1.8 was supposed to be an affordable and compact travel companion. Those were the concepts behind the four initial lenses.
With the six additional lenses that we introduced as development announcements this time, we believe we will be able to deliver more surprise factors, for some models compactness. These two concepts with the addition of these models.
About the Defocus Smoothing technology.
Can you give any insight into the DS technology?
With lens such as the 85mm F1.2 bokeh is a really important factor, because it’s a portrait lens. We really wanted to deliver something that was not possible with the conventional lenses, so we decided to develop this technology of defocus smoothing.
The fact with our DS technology is that it’s a coating technology, so it’s relatively easy to apply this technology to a range of different lenses. This is all we can say at this moment.
