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 It was superseded by the EOS 600D (Kiss X5/Rebel T3i), but remained in Canon's lineup until being discontinued in June 2012 with the announcement of the EOS 650D (Kiss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