Check availablity: Adorama, Amazon USA, Amazon UK, B&H, eBay.

Solid build. Nice contrast. Constant f/4.0 aperture. Good sharpness, but some CA and flare problems. Measured zoom range is closer to 13-23 mm. The lens is usable on a FX body with little vignetting from 17 mm with no lens hood, and from 18 mm with lens hood mounted.

Pentax is supposed to have developed this in cooperation with Tokina, so it should be identical optically to the Tokina 12-24 f/4. However, mechanical construction and coatings are not identical.

Measured zoom range is closer to 13-23 mm.

Company Profile

Key info

Established: 1919
HQ: Tokyo, Japan
Web: Global, EU, US, man

The Pentax brand originated in a company founded in 1919 under the name Asahi Kogaku Goshi Kaisha (Asahi Optical Joint Stock Co.) to make lenses for spectacles. This company introduced the first ever Japanese 35mm SLR (Asahiflex I) in 1952, and enjoyed great success in the 1970ies with its Pentax Spotmatic SLR-series. Its first digital camera, the EI-C90, was introduced in 1997.

The company was renamed Pentax Corporation in 2002, after its camera brand.

Various optical products, including spectacle lenses, DSLRs, compact cameras and the 645D, a 40 megapixel medium format SLR system still carries the Pentax brand.

Since 2011, the Pentax camera business has been a subsidiary of Ricoh.
