When I first saw this result, I suggested that perhaps photodo had tested the lens with the IS left in the ON position. They do tests at various apertures so having the lens mounted on a body will make change of aperture easier, and perhaps they forgot to read the instructions about not using early* IS on a tripod. IS continues to work with the camera's film chamber door open which I guess would be necessary for their sensors to be placed in the film plane. * I'm assuming that the EF 300 f4L IS has the earlier rather than the later version of IS.
FWIW, I've got the non IS version and it's certainly sharp if I manage to hold it really still.
