550 dreview

           Canon's EOS 550D  is the company's latest upper entry-level DSLR. It is announced in February 2010 in North America, it's numerically the successor to the EOS 500D / T1i, although the older model is expected to remain on-sale at a lower price point throughout 2010.

                  Externally the EOS 550D / T2i greatly resembles its predecessor with similar dimensions, weight, build, styling and controls, but as Canon tradition dictates, it inherits a number of key aspects from a higher-end model in the range (in this case the EOS 7D), along with at least one brand new feature.
From the 7D, the EOS 550D / T2i inherits the same 18 Megapixel resolution (albeit with a slightly different sensor), the same 100-6400 ISO sensitivity range (with 12,800 ISO expansion), the choice of 1080p or 720p movies at a variety of frame rates, an external stereo microphone input and the same 63-zone iCFL metering. Continuous shooting is understandably much slower than the 7D, but still slightly quicker than the 500D / T1i at 3.7fps, albeit with fewer frames in the buffer. The EOS 550D / T2i's unique new feature in the EOS range is a 3in 1040k screen with a 3:2 aspect ratio which matches the shape of its sensor.
