Still More Sigma Budget Prime Patents Coming

Oct 14, 2021 | Lenses, News, Patents, Sigma

Sigma applied for design patents (via An Image on a Sensor) (Japanese) for four small, cheap primes from the 24mm to 50mm focal range. They include a couple designs for a 35mm f/2 and one for an f/2 50mm that all have an extra corrective element. Others include an f/2 28mm lens and a 24mm lens of very similar design coming in at f/1.8.

35mm f2 sigma

Sigma recently released a cheap-and-cheerful 24mm f/2, which makes the f/1.8 design referenced above unlikely to be used.
