It looks to be an EF 50mm f/1.4 USM, EF 20mm f/2.8 USM, EF 28mm f/1.8 USM, EF-S 60mm f/2.8 Macro USM, EF 100mm f/2 USM, or EF 85mm f/1.8 USM (the last two are not likely due to how close the camera is to the subjects) with an aftermarket rubber lens hood attached via the filter threads. The lens shown at 0:06 and 0:014 is not an "L" series lens as a gold ring is visible near the front of the barrel.There are also at least two different lenses in the montage: By 0:49 in what appears to be the same scene as at 0:43, what looks like our 20D is back. The appearance of the zoom scale on the LCD in Live View indicates it is probably a "bridge" type camera with a non-interchangeable zoom lens. (Sony did not release the first α body until later in 2006). It is also not any Minolta, Pentax, Olympus, Panasonic, Fuji, nor Nikon digital SLR body that I can find released by May 2006. The one shown at 0:31 and again at 0:43 is not a 20D nor any other Canon digital body produced by May of 2006.There are enough noticeable differences to eliminate the 10D and 30D. The one(s) in the first and last parts seem(s) to be an EOS 20D.There are at least two different camera bodies in your sequence of scenes.
