Something weird just happened: Sigma patented a new 24mm f/2.0 lens for medium format cameras!

Sigma 24mm f/2.0 patent hints at medium-format coverage for Fujifilm GFX and Hasselblad systems

New patent reveals the optical design for a 24mm f/2.0 lens with a larger-than-full-frame image circle.

A newly published patent details a 24mm f/2.0 optical design with an image circle large enough to cover sensors bigger than full-frame—specifically the 44×33mm format used by the Fujifilm GFX and Hasselblad X2D systems. What could this mean in practice?

Possible implications

  1. Sigma designed a 24mm f/2.0 with a very large image circle to deliver exceptional image quality on full-frame with minimal digital correction.
  2. Sigma may be outsourcing or licensing the design for Fujifilm- or Hasselblad-branded lenses.
  3. Sigma could be preparing a native lens for GFX (44×33mm) or Hasselblad’s medium-format mount.
  4. Sigma might be laying groundwork for its own medium-format system.
  5. It could simply be a defensive patent to protect IP without immediate product plans.

You can make up your mind—but I’d certainly love to see Sigma bring lenses to both the Fujifilm GFX and Hasselblad X2D ecosystems.
