New Fujifilm Patents for 28mm f/1.0, 32mm f/1.0 and 35mm f/1.0 Lenses

By on

Here are the new Fujifilm patents for 28mm f/1.0, 32mm f/1.0 and 35mm f/1.0 lenses. Probably only one of these three bright aperture lenses will come to life. Still, it’s nice to see the company working on different primes.

As it is known, Fujifilm currently has the only lens with f/1 aperture. The Fujifilm XF 50mm f/1.0 R WR lens is the world’s first autofocus lens with an impressive and unique f/1.0 maximum aperture. The US price of the Fujifilm XF 50mm f/1 R WR Lens is $1,499.95  and available at Amazon, B&H, Adorama.

Fujifilm has patented the following lenses:

  • Fujinon XF 28mm f/1.0
  • Fujinon XF 32mm f/1.0
  • Fujinon XF 35mm f/1.0

    Name of invention: Imaging lens and imaging equipment
  • In recent years, lens systems with F numbers that are even smaller than the F numbers of the lens system described in patent documents 1 to 4 have been requested.
  • There is a problem that the Gaussian type has a large sajitarkoma aberration when the angle of view is wider, but even though it has a small F number, there is a need for a lens system that can obtain high-quality images by correcting aberration well.
  • In addition, lens systems with small F numbers are desirable because there is a problem of disadvantageous speeding up autofocus because the weight of the group moving at the time of focusing becomes heavier, so it is desirable to reduce the weight of the focus group.
  • This disclosure is considered in view of the above circumstances, and although it has a small F number, it is designed to reduce the weight of the focus group, and the image sensor with high optical performance with good aberration, and an imaging device with this imaging lens. The purpose is to serve.

Fujifilm XF 50mm f/1 R WR Lens: $1,499.95 at Amazon, B&H, Adorama.
