Pentax SMC DA 50mm F 1 8 Recensie | 54 Gegevens vergelijking

The Pentax SMC DA 50mm f/1.8 lens offers excellent optical performance, delivering outstanding sharpness at f/5.6 and very good center sharpness at f/1.8. Weighing just 122g, the lens features internal focusing, a non-rotating 52mm filter thread, and Quick-Shift focusing for easy manual adjustments. However, the lens has a plastic mount and, upon launch, a high £250 price tag for its class. Other drawbacks include a thin, rotating manual focus ring that can catch fingers and the absence of a distance or hyperfocal scale.

The PentaxForums review concludes that the smc Pentax-DA 50mm f/1.8 is an outstanding value, delivering excellent image performance and fast f/1.8 aperture capabilities for under $90. Its key strengths include reliable autofocus, a lightweight yet solid build, and high optical quality, making it an excellent budget-friendly prime option. Conversely, the lens suffers from cost-cutting limitations, such as a plastic lens mount, lack of a focus distance scale, and the omission of a lens hood. Furthermore, the lens does not feature full-time manual focus override (Quick-Shift), which is standard on higher-end Pentax optics.

The Pentax SMC DA 50mm f/1.8 is an highly affordable, budget-friendly prime lens designed specifically for APS-C sensor cameras, giving a full-frame focal length equivalent of around 77mm. Retailing at a highly accessible price point of around 120 EUR/US$, its primary draw is a bright f/1.8 maximum aperture. This allows photographers to achieve a beautifully shallow depth of field and blurry backgrounds that standard kit zoom lenses simply cannot replicate. Additionally, manual focusing operation is notably smooth, and the non-rotating 52mm filter thread offers convenience when using filters. However, the lens suffers from visible cost-cutting measures that limit its overall build and operational quality. The entire lens body, including the lens mount, is constructed entirely of plastic. For autofocusing, it lacks an internal AF motor and must rely entirely on a slotted drive screw operated by the camera body. This design choice results in loud, noisy autofocus operations that are quite sluggish and slow by modern standards. Furthermore, a lens hood is not bundled with the product and must be purchased separately as an optional accessory.

The Pentax smc DA 50mm f/1.8 is an ultra-compact and highly affordable prime lens designed specifically for Pentax APS-C format DSLRs, where it provides a short telephoto effective focal length of 76.5mm. Measuring only 1.5 inches long and weighing a featherweight 122g, this "nifty fifty" alternative serves as an ideal budget-friendly option for portraiture and still-life photography. While its fast f/1.8 aperture facilitates a tight depth of field for smooth, soft bokeh and effective subject isolation, the lens achieves its low price point by eliminating premium optical features like aspherical or extra-low dispersion (ED) glass. It does, however, include Pentax's Super Protect (SP) coating on the front element to help repel moisture and grease. The core advantages of this lens lie in its compact, lightweight construction, highly economical price, and excellent center sharpness when stepped down to the f/4 to f/8 range. On the downside, the lens suffers from noticeably dropped sharpness at the extreme f/1.8 and f/22 ends of the aperture range, though the wide-open softness can occasionally flatter skin blemishes in portrait work. Mechanically, the lens compromises on...

The Ken Rockwell review highlights the Pentax 50mm f/1.8 DA as a compact, budget-friendly lens offering excellent sharpness, neutral bokeh, and smooth mechanical manual focusing. It is praised for its lightweight design and outstanding optical performance, making it ideal for daily use. However, the lens is limited by outdated 1980s screw-coupling autofocus, requiring a camera body motor and lacking quick-shift focus, which causes the focus ring to spin during operation. Additionally, it features inconvenient AF/MF switching and exhibits noticeable focus breathing, according to the review. Ken Rockwell

The smc Pentax-DA 50mm f/1.8 is an ultra-lightweight (122g), compact prime featuring a high-quality plastic construction with a plastic mount and internal focusing that prevents the 52mm filter thread from rotating. It boasts excellent portability, effective SP coating for durability, and Quick-Shift focusing, though it features a loud, screw-driven autofocus system. Handling drawbacks include a poorly recessed, rotating manual focus ring and the lack of a distance scale. Despite these flaws and a budget-oriented build, the lens is lauded for delivering quick, accurate autofocus performance and a bright maximum aperture.

The Pentax smc DA 50mm f1.8 is a compact, ultra-lightweight prime lens released in May 2012, measuring 38.5mm in length and weighing just 122g. Designed for APS-C bodies, it provides a 35mm full-frame equivalent focal length of 75mm, making it a moderate telephoto lens well-suited for indoor portraiture and street photography. According to the DXOMARK Review, the lens achieves an overall DXOMARK score of 25 when tested on a Pentax K-3 camera, though its score drops to 19 points when paired with older bodies like the 16-Mpix Pentax K5. The primary pros highlighted by DXOMARK include its highly accessible price point and excellent aberration control. Lab measurements reveal exceptionally low distortion at 0.1%, minimal chromatic aberration of just 2 µm, and a bright light transmission of 2 TStop. Furthermore, it performs optimally at f/2.8 and limits vignetting to a manageable -0.8 EV. On the downside, the primary con is its sharpness score, which plateaus at 12 P-Mpix. DXOMARK notes that due to this limitation, the lens falls slightly short of the overall capabilities of some of its market rivals when...

The SMC Pentax-DA 50mm f/1.8 is a budget-friendly, lightweight, short-telephoto prime lens designed for APS-C K-mount DSLRs, delivering 35mm equivalent focal lengths for portraiture. It features a fast f/1.8 aperture for depth-of-field control and a Super Protect (SP) coating, with performance highlights including impressive center-frame sharpness, minimal distortion, low vignetting, and negligible chromatic aberration. However, the lens construction is marked by a plastic mount and a lack of weather sealing, reflecting its low-cost design. Performance limitations include a noisy, rudimentary autofocus system, reduced sharpness at the edges when shooting wide open, and a stiff manual focus feel.

The smc Pentax-DA 50mm f/1.8 is a budget-friendly, lightweight (122g) prime lens designed for APS-C sensors, offering exceptional sharpness between f/2.8 and f/11 and smooth bokeh, with some users reporting functional full-frame coverage. Key performance advantages include its cost-effective portrait capability (75mm equivalent) and small, portable footprint. Conversely, the lens is limited by a full-plastic construction, including the lens mount, and relies on a noisy screw-drive autofocus system. Significant drawbacks include wide-open softness, chromatic aberration, and a lack of Quick-Shift manual focus, making it a high-value but budget-focused option.
