Dust and Moisture seals	The D80 is not a well-sealed camera, which is disappointing, but its fit and finish are tighter than the XTi or the Alpha.	The XTi is not sealed, and the fit of its components is not good on the sample we have – there are gaps between body panels, and the camera rattles and creaks in hand.	The Alpha is more heavily-built than the XTi, but it is not sealed either. The memory card door offers less protection than the others, and the user is supposed to leave it open for video output.
