Pentax D FA 150 450mm F4 5 5 6 ED DC AW Análisis | 54 Datos comparados

The PCMag review characterizes the Pentax HD D FA 150-450mm F4.5-5.6 ED DC AW as a rugged, well-built super-telephoto lens that is difficult to highly recommend due to performance issues and a high price point. While it offers outstanding all-weather construction, sharp results at most focal lengths, and useful controls, its slow DC autofocus and image quality drop-off at 450mm hinder its effectiveness for action photography. Key drawbacks highlighted include the heavy, bulky design, lack of internal stabilization, and poor performance at maximum zoom. Despite the solid build, the combination of high cost and limited performance compared to third-party alternatives results in a mixed evaluation from PCMag.

The HD PENTAX-D FA 150-450mm f/4.5-5.6 ED DC AW is a weather-sealed super-telephoto zoom lens designed for Pentax K-mount DSLRs, offering a powerful reach on full-frame bodies and an equivalent 225-675mm focal range on APS-C formats. Built with a tough, robust chassis, the lens weighs 2,000 grams and handles well despite its weight, featuring a quick-shift manual focus system, an AF preset facility, and four customizable buttons for focus control. Optically, it integrates high-definition (HD) and super-protect coatings alongside three extra-low dispersion (ED) elements and one super-low dispersion (SLD) element to maximize light transmission and reduce distortion. However, the review highlights several performance limitations, noting that image sharpness is somewhat lackluster across the zoom range and drops off noticeably at the long end. Its built-in DC autofocus motor delivers pedestrian speeds that lag behind third-party competitors like Sigma and Tamron. Furthermore, the lens completely lacks built-in optical image stabilization, forcing users to rely entirely on in-camera stabilization, which struggles to remain effective at extreme telephoto focal lengths. Finally, mild color fringing and pincushion distortion are present throughout the zoom range,...

The HD Pentax D FA 150-450mm f/4.5-5.6 DC AW is a professional-quality zoom lens that delivers superb build quality and excellent sharpness across its entire focal range. The reviewer notes outstanding performance for stationary subjects, such as birds, at both the lower and upper focal ranges. Key design highlights include rubber barrel grips and a dedicated zoom lock at 150mm to prevent lens creep when carried downward. It also features advanced barrel controls, including focus mode switches and buttons to save a preset focus distance. When paired with a cropped-sensor body like the Pentax K3, the handling balance improves, making it a highly capable tool for wildlife photography. However, the lens comes with several notable drawbacks, primary among them being its hefty 2kg weight, which makes continuous handheld shooting difficult and quickly strains the neck without a tripod or bean bag. The autofocus motor is somewhat slow, raising concerns about its ability to track fast-moving animals, though it suffices for most stationary situations. The reviewer also questions Pentax's design choices, specifically wishing for a faster motor, a wider focal range...

The ePhotoZine review of the Pentax HD PENTAX-D FA 150-450mm f/4.5-5.6 ED DC AW lens highlights its superb build quality, featuring weather-resistant construction, and excellent optical performance, including outstanding sharpness across the frame and low distortion. The lens offers a quiet, quick DC autofocus motor and impressive flare resistance, making it a versatile option for full-frame and APS-C systems. However, the review identifies that the substantial 2kg weight can lead to fatigue, and it notes that zoom creep occurs because the barrel can only be locked at the 150mm position. Additionally, while performance is strong, chromatic aberrations increase significantly at the 450mm maximum focal length.

The HD Pentax-D FA 150-450mm f/4.5-5.6 ED DC AW lens is a robust, weather-sealed super-telephoto zoom, praised for its exceptional build quality, effective AW sealing, and strong, consistent sharpness that peaks at f/8, particularly at the 150mm end. While offering impressive image quality and chromatic aberration control, the lens weighs 2kg and can cause fatigue during hand-held use, requiring tripod support for longer sessions. Performance is excellent overall, but sharpness drops to moderate levels at 300mm wide open, and the lens hood is a separate piece rather than integrated, according to the review.

The HD Pentax-D FA 150-450mm F4.5-5.6 ED DC AW is a robust super-telephoto zoom lens designed for full-frame and APS-C cameras, offering exceptional image sharpness and effective weather sealing. Key pros include fast, silent autofocus, excellent color contrast, effective chromatic aberration control, and useful lens-mounted focus controls. Conversely, the lens is heavy at 2kg, which can make extended handheld shooting fatiguing, and some users find the zoom ring to be overly stiff. Despite these handling limitations, it provides professional-grade results, particularly for wildlife and sports, and works well with the HD DA 1.4x Teleconverter for added reach.

The HD Pentax-D FA* 70-200mm f/2.8 ED DC AW is a pro-grade telephoto zoom lens engineered for both APS-C and full-frame Pentax DSLRs, earning its premium "Star" (*) designation by delivering excellent center sharpness throughout its entire zoom range. Designed for sports and wildlife photography, the lens features a fast, quiet autofocus system powered by a DC motor, alongside Pentax's Quick-Shift Focus System for instantaneous manual focus overrides. Its robust, all-weather construction provides exceptional durability for demanding outdoor environments, making it a highly reliable "holy trinity" lens choice for professional photographers. However, these advanced features result in a remarkably large and heavy build, weighing 1,755g, which makes it cumbersome to carry around and hold during extended shoots. Additionally, its high performance commands a premium purchase price, making it an expensive investment that might not fit everyone's budget. For photographers seeking a more affordable and lightweight alternative, the article suggests considering the HD Pentax-D FA 70-210mm f/4 ED SDM WR instead.
