The Canon 550D DSLR camera includes many significant improvements over the Canon 500D: Better HD motion video, an 18 Megapixel image sensor, and an improved metering system akin to that of the Canon 7D model.The 18MP Image Sensor Image quality of the new Canon 550D is superior to that of previous models – jumping from 12MP to 15MP and finally to an incredible18MP. Partnered with this is the company’s latest DIGIC 4 image processor, and the final result is an incredible combination of processing speed, accuracy, and image resolution.The iFCL Metering System The Canon 550D incorporates the iFCL or Focus, Coloring and Luminance metering system. This system measures and analyses focus, color, and luminance data from 63 zones simultaneously which provides greatly enhanced metering accuracy and consistency over previous models of the line. This is also the same metering system which is used in the Canon 7D semi-professional camera.
The High Definition Motion Video The 550D is much improved in the HD motion video department, as compared to the predecessor 500D especially when shooting at 720p and 1080p. A nice feature is full control over the frame rate which allows you to capture very fast moving images by manual adjustment of the frame rate.The Low Light ISO Improvements The 550D includes a standard ISO range of up to 6400. This range can be expanded up to 12800 for use in low light situations where it may not be allowed or desirable to use flash lighting. This increased ISO range along with the DIGIC 4 image processor makes for minimum graininess in the output image.The New Movie Crop Feature – Standard Definition With The Same Lens A new movie crop function lets you shoot motion video at standard definition with up to 7x effective zoom. This is done by using only the center area of the image sensor, and it is very handy for instances where you do not have time or may not wish to change lenses.The Improved LCD Screen Canon has improved the LCD screen on the 550D over that of previous models too. The screen size is still a very respectable 3 inches, but offers increased resolution and overall clarity which in turn allows you to better see important details in your images as you shoot. The result is better composition ability.
The Strong Product Line Canon has made a great camera – the 500D – even better. And the new 550D is fully compatible with EF and EF-S series lenses so that your existing lenses may still be used. It is also compatible with the EX-Speedlite series of flash accessories. Add to this the features discussed above and the 550D becomes a very attractive & worthwhile upgrade.
