Nikon applied for a patent in japan, A Mirrorless system zoom lens that can be zoomed manually and electronically.
By admin, on December 25th, 2023
Tamron is working on multiple kit lenses, the list includes 15-28mm F2.8, 24-70mm F4, and 24-50mm F2. The most interesting lens is 24-50mm F2, it looks like a perfect alternative to cheap kit lenses we usually get in full-frame mirrorless cameras. Let’s hope these patents may become real products very soon.
Large aperture, or constant aperture-based, short zoom lenses are likely to be in the “25-50mm F2’’ range. These lenses could be more convenient due to their wider zoom range compared to the Sigma 24-35mm F2 DG HSM from the SLR era
Example 1
- Focal length: 16.483-27.168
- F value: 2.910
- Half angle of view: 54.102-37.149
Example 2
- Focal length: 17.515-48.508
- F value: 4.120-4.141
- Half angle of view: 54.004-22.990
Example 3
- Focal length: 25.754-48.493
- F value: 2.060
