Our sister site Photorumors found an interesting patent application the other day. It seems Fujifilm might have a Fujinon XF13mm f1.8 or Fujinon XF20mm f1.8 in the works, but the translation is imperfect. Maybe this patent explains the significant savings on the Fujinon XF 14mm F2.8 R. We will let you know when we know.
Translation:
Fujifilm 20mm F1.8 (equiv.) Patent of Optical technology and lens design]
Fujifilm is Leica at the exchange 20mm F1.8 wide-angle single focus to become a corresponding the is pending.
From left to right, the spherical aberration, astigmatism, distortion, lateral chromatic aberration.
Fujifilm patent application of 1mm F1.8 is an optical system.
The focal length of the entire system seems to scale down the optical design values to be 1mm. By doing this, it will benefit not then understand the product under development in the same industry manufacturers.
So all the angle of view is 95.2 °, Will is considering the 20mm of 14mm (13mm) or for full-size for the APS-C. Back focus is so about 2mm, about 28mm of BF and to scale up to the APS-C, it will be BF of about 40mm and to scale up to full-size. Product will become a short BF, but for now does not mean must shorten the BF because mirrorless Fujifilm will result that the pursuit of optimization that can be considered.
Fujifilm ‘s’ll try, but is to go unusual considering the future because it does not use a non-spherical surface is overlaid, Fujifilm you do not miss the new products.
