The Canon EOS 550D is an 18.0-megapixeldigital single-lens reflex camera, announced by Canon on 8 February 2010.[1] It was available since 24 February 2010,[2] and to US dealers from early March.[3] It is known as the EOS Kiss X4 in Japan, and as the EOS Rebel T2i in the Americas.[4] It is part of Canon's entry- / mid-level digital SLR camera series, and was the successor model to the EOS 500D. It was succeeded by the EOS 600D (Kiss X5 / Rebel T3i) but remained in Canon's lineup until being discontinued in June 2012 with the announcement of the EOS 650D (Kiss X6i / Rebel T4i).[5]
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]
