Canon T2i : Canon 550D DSLR Officially Released. Canon has released a brand new flagship in Canon’s Digital Rebel line, the Canon EOS Rebel T2i also known as the Canon 550D 550D . This brand new EOS is an upgrade of its older sibling, the EOS Rebel T1i (500D).
The T2i uses a new, slightly smaller but more efficient battery to handle movie mode and improve battery life over the T1i. The T2i supports SDHC and SDXC memory card formats, for up to 64GB of storage per card. It’s the first SLR with SDXC support; Canon was first to announce an SDXC-capable camcorder, the HF S21, in January as well (that model will ship in April, just after the T2i’s expected late-March availability).
