Reasons For

3 Reasons For
38% wider field of view Edit
The Canon EOS 550D is a 160% field of view digital camera. That's 60% wider than the Sony Alpha SLT-A77 (100%).
12% higher display resolution Edit
The Canon EOS 550D is a 1,040,000 pixels display resolution digital camera. That's 118,400 pixels higher than the Sony Alpha SLT-A77 (921,600 pixels).
24% lighter Edit
The Canon EOS 550D has a weight of 530g, however the Sony Alpha SLT-A77 is a 653g digital camera (123g heavier). Read more

The camera's weight will depend on the type and size of camera. Compact cameras are usually the lightest while digital SLRs will be heavier. Also consider the number and weight of lenses to take when using a SLR.

The lower the camera weight, the easier it will be to carry around and it will also reduce your hand luggage weight when flying.

4 Reasons For
A lot higher megapixel count Edit
The Sony Alpha SLT-A77 has a megapixel count of 24.3MP, however the Canon EOS 550D is only an 18MP digital camera (6.3MP lower). Read more

The resolution of the images a digital camera produces is measured in megapixels (MP). One megapixel is equal to 1 million pixels and is a result of the pixel width multiplied by the pixel height of the image. While a higher image resolution generally results in sharper images, only a relatively low megapixel count is required when printing the image at a small size or to display it on a computer screen.

A sensor with more megapixels will be able to capture more detailed photos and the image will appear sharper. Images with more megapixels can also be printed at a larger size.

Higher maximum ISO speed Edit
The Sony Alpha SLT-A77 has a maximum ISO speed of 16,000, but the Canon EOS 550D is only a 12,800 maximum ISO speed digital camera (3,200 lower).
Vari-angle LCD display Edit
The Sony Alpha SLT-A77 has a vari-angle LCD display, however the Canon EOS 550D does not have a vari-angle LCD display.
Thirty more shots per battery charge Edit
The Sony Alpha SLT-A77 is a digital camera that takes 470.00 shots per battery charge, whereas the Canon EOS 550D only takes 440.00 shots per battery charge. Read more

The number of shots per battery charge is the number of photos that the camera will typically take on a single charge of the battery.

More shots per battery charge means you will have to recharge the battery less frequently and reduces the need to carry a second back up battery.
