Pentax HD DA 40mm F 2 8 Limited Bewertung | 54 Daten im Vergleich

The HD Pentax-DA 40mm f/2.8 Limited lens is an exceptionally compact "pancake" lens, weighing just 89g and offering excellent build and optical quality with advanced HD coating for reduced flare. It provides exceptional sharpness, minimal distortion, and a smooth bokeh from a nine-blade diaphragm, along with the convenience of Quick-Shift focusing. Drawbacks highlighted include an extremely thin manual focusing ring that rotates during autofocus, the lack of weather sealing, and the absence of a hyperfocal distance scale. Additionally, the lens uses an older, audible screw-drive mechanism for autofocus and is limited in close-up scenarios by a 40cm minimum focus distance.

The HD Pentax-DA 40mm f/2.8 Limited is a highly portable, 15mm-thick pancake lens featuring a robust aluminum body, updated HD multi-layer coatings for improved contrast, and a seven-blade rounded diaphragm. It offers excellent center sharpness wide open, reaching peak performance with outstanding sharpness across the frame at f/8, while including the Quick-Shift Focus System. Performance trade-offs noted include lower edge sharpness at f/2.8, which requires stopping down to f/4 or f/5.6 for optimal results. Furthermore, the lens features a noisy, camera-driven autofocus mechanism and limited close-up capabilities with a 40cm minimum focusing distance.

The Pentax HD DA 40mm f/2.8 Limited is an ultra-compact pancake-style lens designed specifically for APS-C cameras, weighing just 88g with a thin 15.4mm profile. On the positive side, it features an upgraded rounded diaphragm opening, improved coatings, and high-grade aluminium outer construction. Testing shows excellent control over optical flaws, boasting very low chromatic aberration along with well-managed vignetting and distortion. Furthermore, it performs better than its counterpart, the Pentax XS version, which suffers from significantly higher levels of chromatic aberration. However, the lens has several distinct drawbacks, particularly regarding sharpness and overall value. Its overall DxOMark score of 16 points is somewhat disappointing, largely because it lacks consistent sharpness across the frame and is only moderately sharp when shooting wide-open at f/2.8. Center sharpness does not significantly improve until you stop down at least one full stop, and its peak sharpness at f/5.6 is relatively low. Additionally, it relies on a louder, body-based screw-drive mechanism for autofocus rather than a built-in motor. When compared to rivals like the Canon EF 40mm f/2.8 STM, the Pentax underperforms in edge-to-edge uniformity...

The Pentax HD DA 40mm F2.8 Limited is an exceptionally compact, high-performing pancake prime lens designed specifically for Pentax APS-C SLRs. This updated version refreshes a classic design by introducing an improved HD lens coating and rounded aperture blades to enhance bokeh quality and background blur. Key pros include its remarkably tiny form factor—measuring just 0.6 by 2.5 inches and weighing a mere 3.1 ounces—and outstanding center sharpness even when shooting wide open at f/2.8. Additionally, the lens features a handy Quick-Shift Focus System, allowing photographers to make instant manual focus adjustments while autofocus is active. On the downside, the lens completely omits weather sealing, leaving it vulnerable in harsh shooting conditions compared to other options in the Pentax lineup. Its screw-driven autofocus mechanism is also notably noisy, and the incredibly small screw-on metal lens cap is very easily lost if not carefully managed. Furthermore, while it can technically be mounted on full-frame cameras like the K-1, it suffers from excessively soft edges at f/2.8, requiring photographers to stop down to f/4 or f/5.6 to achieve crisp, corner-to-corner performance.

The Pentax HD DA 40mm F2.8 Limited is an exceptionally compact "pancake" lens, measuring 0.6 by 2.5 inches and weighing just 3.1 ounces, offering excellent build quality and stellar image performance on APS-C cameras. Key strengths include strong center sharpness, an advanced HD coating for reduced flare, and surprisingly good performance on full-frame bodies, despite its optimized design for smaller sensors. However, the lens sacrifices modern conveniences for its small size, lacking weather sealing and relying on a noisy mechanical screw-drive autofocus system. While highly praised, users should be aware of a narrow manual focus ring and significant edge softness when used wide open on full-frame cameras.

The HD Pentax-DA 40mm f/2.8 Limited is a premium, ultra-compact "pancake" lens praised for exceptional optical quality, offering sharpness wide open at f/2.8 that becomes superb by f/5.6. Featuring HD coatings to reduce flare and a 9-blade diaphragm for smooth bokeh, this all-metal lens is highly regarded as a versatile, durable tool for travel and street photography. Conversely, the lens's extreme 15mm depth makes handling difficult, with a tiny, rotating manual focus ring and an impractical screw-in lens cap. While capable of covering full-frame, it shows visible vignetting off APS-C, axial chromatic aberration at f/2.8, and utilizes a moderately noisy screw-drive autofocus system.
