PENTAX 21330 70-200mm f/2.8 Telephoto Zoom Lens

Versatile telephoto zoom for Pentax K-mount

The Pentax 21330 is a 70-200mm f/2.8 telephoto zoom lens built for Pentax K-mount digital SLR cameras. It covers a focal range of 70 to 200 mm with a constant maximum aperture of f/2.8, making it suitable for sports, wildlife, landscape and outdoor photography. The lens uses 19 elements in 16 groups and focuses as close as 1.2 m (3.9 ft) for a maximum magnification of 0.13x.

Bundled hood, tripod mount and case extend usability

A PH-RBM77 hood, O-TM80 tripod adapter and HS110-230 lens case are included. The hood reduces flare and protects the front element, the adapter provides stable support on a tripod for long sessions, and the case protects the lens during transport. Together they let you shoot in challenging light, work hands-free with heavy gear and carry the kit securely without buying extras separately.

K-mount limits use to Pentax DSLR bodies

The lens mounts only on Pentax K-mount cameras, so it cannot be used natively on other brands or on mirrorless systems without an adapter that may restrict autofocus or aperture control. The constant f/2.8 aperture holds across the zoom range, but the minimum aperture of f/22 and 9 rounded blades define the depth-of-field and bokeh boundaries you can achieve within this system.
