Sigma patent discloses the design for new 20mm and 25mm f/1.4 MFT lenses
A new patent describes the design of two MFT lenses:
20mm f/1.4
- Focal length: 21.18
- F-value: 1.48
- Angle of view: 59.84
- Image height: 11.15
- Total length: 55.00
25mm f/1.4
- Focal length: 25.00
- F-value: 1.47
- Half angle of view: 49.29
- Image height: 11.15
- Overall length: 56.46
It’s unclear if Sigma will really produce those lenses or if they will license the design to OM Digital/Panasonic.
