| 10 elements / 8 groups |
| f = 34.846 mm |
| FNo = 4.12 |
| 2ω = 83.0° |
| 2 aspherical lenses / 4 aspherical surfaces |
First-group unit focus: G1 (L11-L17 plus the stop) moves objectward while G2 remains fixed. The close-focus dF value is a paraxial estimate for a 0.20 m object distance from the first surface; the patent tabulates only the infinity position.
