Measuring 124 x 92 x 85mm and weighing 500g (1.10lbs), it is a compact and lightweight option. In today’s market, the Alpha 55 may fall short in terms of advanced features and performance compared to newer models. However, it still remains a decent choice for beginners or those looking for an affordable DSLR.

Sony SLT Alpha 55 Overview and Optics

The optics of the Sony SLT Alpha 55 receive a score of 58/100. This camera features a 16.2-megapixel sensor, 10 frames per second shooting speed, and a Bionz processor. Its sensor type is CMOS and has a DXOMARK score of 73. The camera uses an APS-C sized sensor and a Sony Alpha DT lens mount. Additionally, it has image stabilization and a 3:2 aspect ratio.

In today’s market, the optics of the Sony SLT Alpha 55 are considered average. While the 16.2-megapixel sensor and 10 fps shooting speed are decent, they are outperformed by newer models. The DXOMARK sensor score of 73 is relatively low compared to more recent cameras. The APS-C sensor size is common, but larger sensors provide better image quality. The Sony Alpha DT lens mount offers a wide range of lenses, but it is not as versatile as other mounts. The presence of image stabilization is a plus, as it helps reduce camera shake and improve image sharpness.

The Sony SLT Alpha 55’s optics may not be the best on the market, but they are suitable for casual photographers or those on a budget. The camera’s features are decent, but users seeking exceptional image quality and performance should consider other options.

Sony SLT Alpha 55 Video Performance

The Sony SLT Alpha 55 holds a video score of 56 out of 100. Its video capabilities include a maximum resolution of Full HD (1920 x 1080) and a frame rate of 60fps. However, it lacks built-in time-lapse functionality.

Comparing these specifications to today’s market, the Alpha 55 falls behind more advanced cameras. Full HD video resolution is still common, but 4K resolution has become increasingly popular, offering higher quality footage. The 60fps frame rate is acceptable, but cameras now offer 120fps or even 240fps for smoother slow-motion video. The absence of time-lapse functionality is also a drawback, as it is a sought-after feature in modern cameras.

The Sony SLT Alpha 55’s video capabilities are decent but not exceptional. In the current market, there are more advanced options for videographers.

Sony SLT Alpha 55 Features and Benefits
