HD Pentax-D FA 150-450mm F4.5-5.6
Back in June 2016, we presented our first review of the HD Pentax-D FA 150-450mm F4.5-5.6 ED DC AW, which was the first member of the new lineup of full frame zoom lenses from Pentax. At the time, the review had been performed with a K-3 camera body as the full-frame K-1 had been announced but not yet released. Now that the K-1 has been out for some time and more users have access to it, it is time to revisit our review, this time testing the lens wih a full frame sensor.
This long-awaited telephoto zoom made its debut in early May, 2015 as the first of a growing series of Pentax full frame lenses. This 5-pound behemoth is packed with Pentax's latest technologies, including three focusing modes, dedicated AF buttons on the lens barrel, a silent DC focusing system, the premium HD lens coating, and a super low dispersion glass element for superior aberration control. It offers the longest focal length for a zoom in the current Pentax lens lineup, and thus fills an important gap that had previously existed beyond 250mm. Its 150-450mm zoom range also complements the existing DA* 300mm F4 and DA 560mm F5.6 primes very nicely.
Although this lens was designed with full frame DSLRs in mind, it also works wonders on current APS-C bodies such as the Pentax K-70, K-S2, and K-3 II. During our preliminary review with a crop sensor, we were impressed by the lens's performance. Today we are ready to present a full in-depth review using a K-1 full-frame camera body. We will revisit the construction, handling, and focus speed on full frame, and analyze the optical performance including sharpness, bokeh, aberrations, distortion, vignetting.
If your primary area of interest lies in photographing wildlife, birds, sports, or events, we feel that this lens has the potential to become a key component of your kit. Read on to learn more about how it stood up to our tests!
