.. Nothing!
See: http://www.eisa.eu/awards/3/photo.html (N.B. Content of this page is updated every year!)
Canon, Nikon, Sony, Olympus, Panasonic, Fujifilm, Samsung, Sigma and Tamron are all there, except Pentax!
IMHO, these awards are selected in a way that every brand could appear as the winner(s) for different categories as far as possible, already! :-o
