The NA-550D housing is the latest member of the Nauticam family designed to accommodate the hugely popular Canon 550D, Canons latest upper entry level DSLR with 1080p HD video function.

The NA-550D housing inherits the renowned piano keys from NA-7D housing and the signature port locking system. The top piano key/rocker key controls AE lock, the middle for AF point selection, and the bottom provides access to the quick control button. One particularly innovative feature of the housing is the play back button, located below the camera's cross keys, and now accessible at the left top side of the housing. This means you can easily play back images underwater with your left thumb while keeping both hands on grips. The housing also features a new fingertip ISO paddle, for changing ISO speed located on the top of the housing. We have also worked on the sensitivity of the shutter release lever which incorporates an enhanced mechanism, allowing a very responsive half-press autofocus.
