At the PMA show yesterday, Pentax announced a new Limited Series lens, the DA 15mm f4 ED AL Limited. The ultra-wide angle lens has a 23mm equivalent in 35mm terms and has a closest focusing distance of 6 inches. The lens has an aspherical (AL) lens element, and an extra low dispersion (ED) lens element to minimize chromatic aberrations and ensure image quality. Image distortion is claimed to be extremely low for an ultra wide-angle lens.

As with others in Pentax's Limited lens series, it is built to a high-quality standard, featuring the lens barrel, cap, and built-in hood made of high-grade aluminum. The flower-shaped built-in lens hood is a great feature. The lens cap screws on and is felt-lined to help protect the front element.

The lens will ship in April 2009 for $649.99.
