The Japanese Kancolle strategy wiki's page for Isonami includes a long digression on why Isonami's camera in this pic must be a Nikon rather than a Canon, basically because Nikon from its beginnings was a major manufacturer of optical equipment for the Imperial Japanese Navy, while Canon was much more affiliated with the Army (cue booing and hissing from IJN shipgirls). Said digression then digressed even further into the long postwar struggle between Nikon and Canon for SLR camera supremacy. Otakus will otaku, I guess.
