The smc DA 15mm F4 ED AL Limited is Pentax's latest lens, which was shown in prototype form at Photokina 2008 and formally introduced in March 2009. It's a rare beast indeed: a wide angle fixed focal length ('prime') lens that is purpose-designed for APS-C format digital SLRs. The 15mm focal length gives an angle of view equivalent to a 22.5mm lens on the 35mm format; in essence, this lens is the modern equivalent of old favorites such as the 24mm F2.8 or the 21mm F3.5. The 'Limited' tag denotes premium construction, with the lens barrel made entirely from high-grade aluminium, which comes as a refreshing change from the engineering plastics used almost universally by other manufacturers.
The Pentax HD DA 15mm F4 ED AL Limited is an impressively sharp wide-angle lens with minimal distortion.
As a 23mm equivalent the Pentax 15mm f4 Limited is the firm’s premium quality wide-angle choice, and like the rest in the series it’s serious compact. Read on to find out how well this newly revised HD version performs.
