Sony SLT-A55 Recensie | 108 Gegevens vergelijking

The DPReview of the Sony SLT-A55 highlights the camera as a groundbreaking model featuring a fixed, semi-transparent mirror design that enables 10 frames-per-second continuous shooting with active phase-detection AF. Key advantages include its 16.2MP APS-C sensor, excellent full-time live view, and an articulated screen, which collectively bridge the gap between traditional DSLRs and mirrorless systems. However, the unconventional design has drawbacks, such as an AF system that struggles with fast-moving action and a tendency to overheat during extended video recording. Additional cons include limited manual control in video mode, a 2-second lag during image review, and significant battery drain from the sensor-shift image stabilization system.

The Sony Alpha SLT-A55 is recognized as an innovative, high-value camera using Single Lens Translucent technology to deliver 10 fps burst shooting and continuous autofocus, outperforming traditional DSLRs in speed at its price point. Key benefits include the 16.2-megapixel sensor, integrated GPS, SteadyShot image stabilization, and effective, fast-focusing AVCHD video capability. However, the design forces reliance on an electronic viewfinder, which critics found struggles with noise and clarity in low light. Performance bottlenecks include slow buffer clearing for large RAW bursts and restricted manual control for video, which lacks manual exposure adjustments, limiting creative control for advanced videographers.

The Sony Alpha 55 (A55) is an innovative camera praised for its competitive $799.99 retail price and its unique Translucent Mirror Technology, which uses a fixed, semi-translucent mirror to project a Live View feed onto an electronic viewfinder or its 3-inch tiltable LCD screen. This architecture allows for exceptional autofocus speed and performance while recording Full HD 1080/60i video or using Live View, making it a powerful contender for hybrid shooters. The camera features a 16.2MP high-resolution sensor, built-in GPS for geotagging, and an impressive 10 frames per second continuous shooting capability, which is unmatched in its price class. Testing with the Sony 70-200mm f/2.8 G and Sigma 30mm f/1.4 lenses demonstrated solid build quality with an ergonomic design, including a protruding eyepiece that keeps the user's nose off the screen and convenient button layouts for quick, single-handed setting adjustments. However, the camera comes with notable tradeoffs that make it less suitable for studio or strict portrait photographers. A major drawback is its poor battery life, which drains rapidly due to the high energy demand of processing the live view...

Sony A55 Video Review Summary The Sony Alpha SLT-A55V breaks new ground in interchangeable-lens cameras by using a radical Translucent Mirror design to achieve full-time phase detection autofocus (AF) during video recording. This design continuously redirects a portion of incoming light to a dedicated AF sensor, allowing for fast, direct focusing with minimal hunting compared to traditional contrast-detection systems. The camera records high-definition video at up to 1080i at 60 fields per second in the space-efficient AVCHD format, alongside a computer-friendly 1080p MPEG-4 option. It features dual internal microphones for stereo sound, a 3.5mm external microphone jack, built-in GPS for movie geotagging, and an electronic viewfinder that aids manual focus in bright sunlight. However, the innovative autofocus system introduces significant compromises, primarily because the lens aperture must remain locked wide open during AF mode. This forces the camera to control bright exposures through shutter speed and ISO alone, often creating a noticeably choppy look due to reduced motion blur, while also displaying typical rolling shutter artifacts on moving subjects. Furthermore, using Alpha-mount lenses results in obtrusive autofocus drive noise on...

ePHOTOzine characterizes the Sony Alpha a55 as a highly responsive, innovative camera featuring a lightweight design with logically placed, accessible controls. The review highlights the exceptional electronic viewfinder (EVF) and the versatile rear screen for composition, alongside a superb electronic level indicator. ePHOTOzine Conversely, the review notes a "con" in the camera's highly plastic build quality, which reduces confidence in its durability for heavy-duty use. Additionally, the otherwise excellent EVF is marred by noticeable colour fringing, which can make prolonged, eye-level viewing uncomfortable.

The What Digital Camera review gives the Sony Alpha A55 a 91% score, highlighting its innovative SLT technology, 10fps continuous shooting, and effective 1080i HD movie autofocus. Pros include built-in GPS and smooth tracking capabilities, though the 10fps speed priority mode suffers from a 45-second buffer clearing time. Cons include limited manual control in video mode, requiring lens switch toggles for focus changes, and potential sensor overheating when using image stabilization during video recording.

The Trusted Reviews analysis highlights the Sony Alpha SLT-A55 as an innovative, feature-rich alternative to traditional DSLRs, utilizing Translucent Mirror Technology to deliver a blistering 10fps continuous burst mode with exceptional tracking. Key strengths include integrated image stabilization, built-in GPS, and highly responsive 1080i HD video autofocus, making it a compelling, compact option for fast-action photography. Conversely, the review notes that the electronic viewfinder (EVF) may not suit all users, particularly due to sub-par performance in low-light conditions. Additionally, the camera's compact design lacks extensive physical controls compared to traditional DSLRs, requiring increased reliance on menu navigation for adjustments, and the video mode offers limited manual control.

The Sony A55 is reviewed as a highly capable, compact, entry-level camera that introduces an innovative translucent mirror design. Key pros highlighted in the review include its ultra-fast live view autofocus system for stills and its 16.2MP CMOS sensor, which delivers solid image quality that stands up well against key competitors like the Canon 60D and Nikon D7000. Additionally, it features sensor-based image stabilization that stabilises every attached lens, an external microphone port, and a built-in GPS that automatically geotags images. The physical handling is also praised for its intuitive layout and user-friendly display interface. On the downside, the review identifies several notable cons, particularly regarding performance speeds and video functionality. A major flaw is the continuous shooting buffer; despite the camera's ability to hit a fast 10 frames per second, it takes an unacceptable 30+ seconds to recover after shooting a burst of RAW files, making it a poor choice for action sequences. Furthermore, while the autofocus functions during video capture, it transitions between subjects far too quickly and unnaturally compared to traditional camcorders. Finally, the camera's physical grip...
