Firmware updates
    
In July 2010, Canon released firmware 1.0.8 that fixed a phenomenon in which the set aperture moves unexpectedly when shooting movies in manual exposure mode using some Canon lenses (such as macro lenses).[9] On 25 December 2010,[10] Canon offered firmware version 1.0.9 which fixed tone jumps in some images, depending on the shooting scene and when shooting with the Auto Lighting Optimizer settings (low / standard / strong).[11]
Custom firmware
    
Magic Lantern is an open-source (GPL) firmware add-on for Canon DSLR cameras, which has enhancements for video and still photography without replacing the stock firmware.[12] The Canon T2i is compatible with Magic Lantern firmware.[13]
Reception
    
The British Journal of Photography was impressed by the 550D and said "the EOS 550D is a good match for the 7D at half the price".[14] On Digital Photography Review, it got overall score of 77%.[15] For most of its product life, alternative cameras included the Nikon D5000, Nikon D3100, Canon 500D,[16] Nikon D90,[17] and Pentax K-7. Immediately before it was discontinued in 2012, the main competitors of the 550D were the Nikon D3200 and D5100 (respectively the replacements for the D3100 and D5000), Pentax K-r (replacement for the K-x), and the Sony Alpha 57, one of the company's SLT cameras. (The replacement for the Nikon D90, the D7000, is positioned upmarket from the 550D.)
