A constant F2.8, start to finish
The maximum aperture stays at F2.8 across the entire 76-214mm equivalent zoom range, so exposure and depth of field don't shift as you zoom — one less thing to think about when the light or the moment is moving fast.
- 23 elements in 16 groups, including 6 low-dispersion elements
- Constant maximum aperture F2.8 across the full zoom range
