Pentax SMC DA 16 45mm F4 0 ED AL Bewertung | 54 Daten im Vergleich

The Pentax DA 16-45mm F4 ED AL is positioned by DPReview as a specialized upgrade from kit lenses, offering a constant F4 aperture and a 24mm-equivalent wide-angle view. Key performance strengths include very low light fall-off, minimal barrel distortion at the wide end, excellent macro capabilities, and the convenience of a "Quick Shift" manual focus system. Conversely, the review notes the lens suffers from softness at the 16mm setting and noticeable chromatic aberration at focal extremes. Physical design compromises include a reverse-extension mechanism that is longest at 16mm, lateral barrel play, and a relatively limited 45mm reach on the telephoto end.

The Pentax smc DA 16-45mm f/4 ED AL is a lightweight, travel-friendly standard zoom for APS-C cameras, offering a constant f/4 aperture, excellent center-to-edge sharpness at f/8, and very strong wide-angle performance. The review highlights its value for money and effective control over distortion and chromatic aberrations, making it a capable, cost-effective option. However, the lens suffers from a slight loss of sharpness in the 28mm mid-range at maximum aperture, requiring stopping down to f/11 for optimal results, and it lacks weather sealing. Additionally, the autofocus is noisy, and the 45mm telephoto end provides limited background blur for portraiture.

The Pentax 16-45mm f/4 SMC DA ED AL is a compact, 365g standard zoom lens designed for Pentax DSLRs, offering excellent optical performance, particularly strong center sharpness at 16mm and low levels of distortion and chromatic aberration. While the lens provides great value with its high-refractive ED glass, it features an unconventional "reverse zoom" design where the barrel extends to its maximum length at the 16mm setting. Drawbacks identified in the review include a functional but non-premium construction and a somewhat limited, modest zoom range compared to more versatile walkaround alternatives. Ultimately, the lens is considered an ideal, high-performing choice for users not requiring a faster aperture than f/4 or a long telephoto reach, offering great responsiveness for its price.

The What Digital Camera review of the Pentax SMC DA 16-45mm f/4 ED AL lens highlights it as a solid, digitally dedicated optic from Pentax's KB range that achieves near-perfect optical consistency across its aperture and focal range. The review praises its high-resolution and high-contrast performance, noting that center sharpness reliably exceeds 1000lwph. Its compact build incorporates 13 elements in 10 groups, using aspheric and extra-low dispersion (ED) glass elements designed to minimize optical distortion and promote strong color accuracy. Despite lacking ultra-quiet drive motors, the autofocus operates efficiently through the camera body, making it adequately fast even for dynamic subjects. However, the reviewer points out several design and performance concessions required to maintain its accessible price point. A primary drawback is the increased chromatic aberration at wider angles, which manifests as a noticeable 3 to 3.5-pixel rise in color fringing from the center to the frame's corners. Physically, the lens features a plastic inner barrel that unusually extends outward as you zoom toward the wide-angle end. While the outer barrel is metal and gives the overall construction a rigid...

The SMC Pentax-DA 16-45mm F4 ED AL lens is highly regarded on PentaxForums as a sharp, budget-friendly alternative to kit lenses, offering excellent image quality, high contrast, and a constant f/4 aperture. Key advantages cited by users include the useful 16mm wide-angle, solid build, and effective close-focusing capabilities. However, the lens is noted for a "reverse zoom" design that extends at 16mm, causing shadows when using the built-in flash. Additional disadvantages mentioned in user reviews include high chromatic aberration at the wide end, a lack of weather sealing, and soft corners when shooting wide open.
