The same constant F2.8 zoom, far lighter
The Mark II keeps the constant F2.8 standard-zoom range of the original R LM WR, but a reworked optical formula trims the weight and length substantially.
- 16 elements in 11 groups, including 4 aspherical, 3 ED, 1 Super ED element
- Constant maximum aperture F2.8 across the zoom range
- Approximately 410g, excluding caps and hood
