What this lens is good for
Compact PRO telephoto
An 80-300mm full-frame equivalent at constant f/4, weather sealed, and remarkably compact for the reach, an alternative to the larger f/2.8 PRO for those who want sealing and quality without the weight. It suits portraits, events, and travel telephoto work. Full guide →
Portraits and detail
The constant f/4 aperture and sharp PRO optics give clean subject separation for portraits and detail, and the close 0.35m focus adds near-macro flexibility. The sealing makes it dependable outdoors, and the small size makes it easy to carry.
