The Sony Alpha 550 earns a score of 44/100 in our evaluation. Introduced on August 27, 2009, this DSLR camera was initially priced at $899. Measuring 137 x 104 x 84mm and weighing 632g (1.39lbs), it has a relatively compact and lightweight design for its time.

However, considering the rapid advancements in camera technology, the Alpha 550’s specifications may not hold up well in today’s market. Despite its solid build and respectable launch price, newer models offer superior performance and features.

Sony Alpha 550 Overview and Optics

The optics of the Sony Alpha 550 receive a score of 48 out of 100. This camera features 14.2 megapixels, a shooting speed of 7, and a CMOS sensor type. Its processor is Bionz, and the DXOMARK score for the sensor is 66. The sensor size is APS-C, with a Sony Alpha DT lens mount. Additionally, the camera has image stabilization and a 3:2 aspect ratio.

In today’s market, the Sony Alpha 550’s specifications are not as competitive as they once were. The 14.2-megapixel count is lower than many current cameras, and the shooting speed of 7 is also not as fast as some newer models. However, the image stabilization feature remains valuable for photographers seeking steady shots.

The Sony Alpha 550 is a solid camera with decent optics, but it may not be the best choice in the current market. Its specifications are somewhat outdated, and there are more advanced options available for photographers seeking top-of-the-line performance.

Optics	Sony Alpha 550
Megapixels The higher the number of megapixels, the more detail the cameras sensor can capture.	14.2 MP
Image Resolution Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.	4592 x 3056 px
Sensor Type The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality.	CMOS
Sensor Size The sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture.	15.6 x 23.5 mm
Sensor Format Refers to the most commonly used sensor sizes.	APS-C
Frame Rate The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode.	7 fps
Lens Mount The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras.	Sony Alpha DT
Image Processor The image processor in the camera converts the information collected on the sensor for digital storage on the memory card.	Bionz
Aspect Ratio The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3.	3:2
Minimum ISO (Native) Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.	200
Maximum ISO (Native) Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.	12,800
Minimum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.	200
Maximum ISO (Expanded) Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.	12800
Minimum Shutter Speed The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory.	30 s
Maximum Shutter Speed The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries.	1/ 4000 s
Autofocus Points Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings.	9
In-body Stabilization In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake.
Viewfinder Type The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens.	Optical (pentamirror)
