Sigma Interview at CP+

DPReview sat down with Sigma at CP+ and had a wide ranging interview with CEO Kazuto Yamaki.  Kazuto is widely known for his honest, and clear answers to some of the technical hurdles facing Sigma and also the future plans of Sigma.

We summarized the interview below, but go here to read the full interview.

  • Maybe in the future, Sigma will create smaller, F2.0, etc primes instead of their Sigma Art lenses
  • Working on making sure Sigma lenses work well through mount adapters for Canon RF and Nikon Z mounts
  • Concerns about the elements being so close to the sensor on the Nikon Z mount, adding to problems such as ghosting.
  • Shorter flange back and bigger mount diameter (as seen in the Canon RF and Nikon Z) offers more flexibility than for instance the Sony E mount.
  • Common lenses would be designed for the narrowest mount, or the longest flange distance - or both.
  • CDAF requires the lens focus elements to be very light so they can move quickly in small steps
  • The design software that Sigma uses simulates bokeh so they check it before they design the lens.
  • Sigma is impressed with the Canon 28-70 F.20 and the Canon RF 50mm 1.2
