Tamron Patent Application: 18-55mm F3.5-5.6 for APS-C Mirrorless
This is kind of an odd patent application, Tamron has applied for a patent on a 18-55mm mirrorless APS-C lens. I mean, who doesn't already make one of these?
What would have been more interesting is perhaps a 2.8-4.0 design such as what Fujifilm makes for their premium kits.
One of the embodiments is shown below;
Focal length: 18.5452 30.0017 53.3331 mm
F number: 3.5704 4.2677 5.7338
Half angle of view: 38.3105 25.5570 14.7739
Image height: 13.43 14.20 14.20 mm
