The Pentax SMCP-DA 12-24mm f/4 ED AL lens was developed for exclusive use with Pentax digital SLR cameras, and is a compact, lightweight two-times zoom lens that offers an ultra-wide-angle perspective equivalent to 18.5mm to 37mm in the 35mm format.

The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLR cameras to optimize camera performance. This design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Note: Not suitable for 35mm film SLR cameras.
