Sony A550 DSLR Sony DT 18 55mm F3 5 5 6 SAM Recensione | 108 Dati a confronto

The DPReview evaluation highlights the Sony Alpha DSLR-A550 as a feature-rich, 14.2 MP camera boasting a 7 fps burst mode, excellent high-ISO noise handling, and a highly capable secondary-sensor Live View system. Key strengths include superb RAW file quality, built-in image stabilization, and long battery life. However, the review notes major drawbacks, specifically the complete lack of video recording, sluggish memory card write speeds, and a confusing interface. Additional cons include fixed exposure/focus during high-speed shooting and a lack of advanced ergonomic features like a dedicated depth-of-field preview.

Sony Alpha A550 Review Summary The Sony Alpha A550 is an enthusiast-focused digital SLR camera featuring a 14.2-megapixel APS-C Exmor CMOS sensor and a redesigned BIONZ image processor. A standout innovation is its unique "Quick AF Live View" system, which utilizes a secondary sensor in the pentamirror to allow fast phase-detection autofocusing and face detection while using the tilting 921,600-dot LCD screen. Performance is a major strength, as the camera delivers an impressive burst shooting rate of up to 7 frames per second in Speed Priority mode, backed by a generous image buffer and a battery life rated for 950 shots via the optical viewfinder. Furthermore, it introduces a highly efficient, handheld-friendly Auto HDR feature that takes two micro-aligned exposures in just two seconds, as well as an improved SteadyShot INSIDE sensor-shift stabilization system offering up to 4 stops of correction. However, the A550 is held back by several ergonomic and structural drawbacks. The physical build is notably thick front-to-back, making the camera feel bulky, chunky, and less substantial than higher-end competing digital SLRs. Its handgrip is awkwardly narrow and...

The Sony Alpha DSLR-A550 is a mid-range, speed-oriented DSLR designed for photography enthusiasts, bridging the gap between entry-level models and semi-professional bodies. Built around a 14.2 Megapixel Exmor CMOS sensor, it delivers significantly upgraded burst performance and vastly improved low-light capabilities compared to its CCD predecessors. A major highlight is its unique dual Live View implementation: a quick-focus mode using a secondary sensor in the viewfinder head for uninterrupted phase-change autofocus, and a dedicated "Manual Focus Check" mode that feeds directly from the main sensor for 100% frame coverage and pixel-level magnification. This framing flexibility is further enhanced by a 3-inch vertically-tilting VGA screen and an in-camera HDR mode. Despite its competitive speed and excellent ergonomics, the camera has notable feature omissions that hold it back. Its most glaring downside is the complete lack of video recording capabilities, failing to keep up with contemporary rivals that offer HD video. Additionally, while its primary Live View mode is incredibly fast, it only provides a 90% view of the actual image area, forcing users to rely on the manual focus check mode...

Sony Alpha DSLR-A550 Review Summary The Sony Alpha DSLR-A550 is a mid-range digital SLR camera that delivers a mix of high-speed performance and strong low-light capabilities for its price point. Built with a 14.2-megapixel Exmor CMOS sensor, it produces sharp, clean images with an impressive high ISO sensitivity profile that effectively suppresses noise up to ISO 3,200. Its standout features include a fast Live View autofocus system and a large, tiltable 3-inch LCD screen that makes shooting from awkward angles much easier. It also powers on quickly in 0.4 seconds, boasts a zippy 0.3-second autofocus lag in good lighting, and features a useful "Auto HDR" mode that merges two sequential exposures to capture enhanced highlight and shadow details. Despite these performance strengths, the camera suffers from notable design and image processing flaws. The default Creative Styles result in poor color accuracy and oversaturated tones, an issue that frustratingly persists even when shooting in RAW format. Structurally, the camera is awkwardly optimized for traditional viewfinder shooting. The optical viewfinder is small, offers a low magnification factor, and provides only 90% coverage...

The Sony Alpha a550 is a feature-packed 14.2-megapixel DSLR optimized for live-view shooting, offering a 3-inch tilting LCD and a 7 fps Speed Priority mode. Pros include excellent low-light performance up to ISO 12,800, effective in-camera HDR, and an improved, comfortable grip. Key cons include the lack of a movie recording mode and a somewhat plastic construction, say reviewers. Additionally, the kit lens suffers from softness, and high ISO settings above 6400 produce high noise levels.

The OpticalLimits Review outlines the Sony DSLR-A550 as the top-tier model in Sony's intermediate APS-C lineup, blending the high 14.2-megapixel resolution and fast frame rates of the A450 with the large, tilting LCD screen and "Quick AF Live View" of the A500. Evaluated alongside competitors like the Canon EOS 500D and Nikon D5000, the camera stands out for its impressive continuous frame rate of 5 to 7 fps and a unique CCD sensor-shift system that pulls double duty for both image stabilization and dust reduction. Furthermore, testing shows it captures a broad, competitive dynamic range of up to 12 f-stops at low ISO settings, which handles high-contrast scenes effectively. However, the reviewer highlights several notable drawbacks concerning its design and overall output quality. While raw files deliver a solid, competitive performance up to ISO 800, the in-camera JPEG processing results in significantly worse output, making it a poor choice if maximizing fine resolution is a priority. Low-light shooting is further hindered by extreme image noise at maximum sensitivities (ISO 6400 to 12800), an unprogrammable bulb exposure mode, and a small,...
