Pentax SMC DA 70mm F2 4 Limited Bewertung | 54 Daten im Vergleich

The LensTip.com review of the Pentax smc DA 70 mm f/2.4 Limited highlights this short telephoto prime as an exceptionally compact, portrait-length pancake lens built for KAF mount reflex cameras. Designed with an attractive, retro-styled metal barrel, it delivers outstanding value and performance. The key advantages noted in the review include an exceptionally solid and lightweight build, brilliant image resolution in the frame centre even when shot wide open at f/2.4, and very respectable sharpness along the edges when stopped down slightly. Optically, the lens shines with practically nonexistent distortion (measured at a negligible 0.68% pincushion), superbly controlled chromatic aberrations, and high resilience against ghosting and flares when working under harsh backlighting. Additionally, its autofocus mechanism functions efficiently and with good overall speed. On the downside, the lens is not completely devoid of compromises due to its ultra-flat pancake dimensions. The primary flaw emphasized by LensTip is its high level of vignetting. When shooting wide open at the maximum f/2.4 aperture, the lens suffers a noticeable light fall-off of up to 30% (-1.05 EV) in the frame corners. While this...

The ePHOTOzine review of the SMC Pentax-DA 70mm f/2.4 Limited lens highlights its superior all-metal construction, compact design, and fast autofocus, making it excellent for portrait and travel photography. Key advantages include outstanding central sharpness between f/5.6-f/8, the convenient Quick Shift focus system, and a unique built-in extending hood. While the lens offers high overall quality, disadvantages include only "fairly good" edge sharpness at f/2.4, a limited minimum focusing distance, and a focus ring that lacks the tactile feel of older, fully manual lenses. The lens is recommended for its portability and excellent center performance despite these minor limitations.

The Pentax SMC DA 70mm f/2.4 Limited is a highly capable and affordable "pancake" lens built specifically for APS-C format cameras. It stands out for its exceptional physical engineering, boasting an all-metal outer shell, tight manufacturing tolerances, and a smooth, slightly dampened focus ring. With a full-format equivalent focal length of 105mm and a relatively fast maximum aperture, it is perfectly suited for portrait photography. Additional operational benefits include a non-rotating 49mm filter thread and the "Quick-Shift Focus System," which allows users to effortlessly override autofocus and manually tweak their shot without turning off the AF switch. Despite its high-quality construction, the lens has notable compromises regarding its physical footprint and autofocus system. While its extremely flat design is highly portable, using the supplied telescope-style screw-in metal hood nearly doubles the physical length of the lens. Furthermore, it relies on a legacy slotted drive screw powered by the camera body rather than incorporating an internal autofocus motor. This mechanical design choice means autofocus operations generate a moderate level of audible noise, and the lens barrel physically extends outward when tracking...

The SMC Pentax-DA 70mm f/2.4 Limited lens is described as a superbly engineered, ultra-compact prime offering exceptional handling and high-quality construction. Its excellent optical performance makes it an ideal choice for portraiture and general medium-range photography, yielding distinct aesthetic characteristics. While the lens excels in build and sharpness, it is not designed for macro photography, limiting its close-up versatility. Despite this, its superior mechanical construction and portability solidify its reputation as a top-tier choice for Pentax users.

In his Cameralabs review, Gordon Laing evaluates the Pentax DA 40mm f2.8 and DA 70mm f2.4 Limited lenses using a Pentax K10D body. The review highlights the extraordinarily compact "pancake" physical design of these premium, digital-only prime options. The 40mm measures a tiny 15mm thick, while the short telephoto 70mm portrait lens is a mere 26mm thick. Laing praises both lenses for their excellent premium build quality, outstanding background blur (bokeh), and their inclusion of helpful physical features like Pentax's Quick-Shift manual focus override system. However, the review details specific performance trade-offs resulting from these ultra-slim form factors. On the downside, the DA 40mm displays some optical softness and delivers good but not exceptional results in landscape shots. Meanwhile, the DA 70mm can suffer from visible coloured fringing (chromatic aberration) in the middle of the frame when used wide open. Additionally, because neither lens houses an internal autofocus motor, they are audibly loud when focusing. Their tiny barrels offer very little space to grip, meaning your fingers can easily be nudged as the external manual focus rings spin during autofocus....

The Pentax smc DA 70mm F2.4 Limited review on DXOMARK evaluates this compact prime telephoto lens, which was released in September 2006, by testing its optical performance on the Pentax K-3 DSLR. The lens achieves a DXOMARK Score of 22, with its peak performance occurring at a focal length of 70mm and an aperture of f/2.8. Optically, the lens exhibits strong attributes including a sharpness score of 11 P-Mpix, an exceptionally low distortion level of just 0.2%, and highly controlled chromatic aberration measuring at 6 µm. On the downside, the test metrics reveal a few notable optical limitations that compromise its overall performance. The lens registers a transmission loss score of 2.7 TStop, which indicates that less light reaches the sensor than the physical f/2.4 aperture would otherwise suggest. Additionally, it suffers from a vignetting effect of -0.8 EV, pointing to visible corner darkening when shooting at wider settings. While the lens delivers robust sharpness and negligible distortion, users must contend with these minor light transmission and corner shading penalties.

The SMC Pentax-DA 70mm F2.4 Limited lens is highly regarded on PentaxForums for its premium metal "pancake" construction, weighing just 130 grams, and delivering exceptional image quality with vibrant contrast and sharp performance from f/2.4. Users praise its smooth bokeh for portraits and compact size, making it a versatile prime for travel or everyday shooting. However, the lens is noted for having some corner softness wide open, minor color fringing, a loud screw-drive autofocus system, and a finicky, short-threaded screw-on metal lens hood. Additionally, some users find the f/2.4 maximum aperture restrictive compared to other lenses in the Limited lineup.
