Pentax HD DA 15mm f4 Limited lens review: Compelling choiceBy Kevin Carter - Friday January 03 2014 Lens Review
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.
There can be few lens series that are so highly regarded by their users than the Limited range of primes from Pentax. Not only are they well made but the images they produce have a distinctive descriptive quality, or ‘drawing style’, that makes particularly attractive to serious enthusiasts. As a revision to the previous smc version the new HD model has rounded iris for smoother transitions to out-of-focus areas and it has new coatings for improved transmission and color while also lowering flare and ghosting from internal reflections. The optical design is unchanged but utilizes extra low dispersion glass and a hybrid aspherical element for lower chromatic aberration and improved sharpness. With a horizontal angle of view of 76-degrees, this particular AF-equipped model is comparable to a full-frame 23mm and yet measures just 1.6-inches (40.6mm) in length, has a 49mm filter thread and weighs just 6.7 oz (190g). It’s available now for $699.
