Sony is best known as a giant electronics manufacturer making devices across a range of markets, but its camera division is doing especially well. The market for compact point and shoot cameras has fallen, but Sony is doing very well with its professionally-orientated full-frame A7 series and A9 mirrorless cameras. It also makes a continually expanding range of high-end professional lenses.
Sony also developed a range of SLT cameras, a kind of hybrid between DSLRs and mirrorless cameras. It also makes Cyber-shot compact cameras and a range of higher-end broadcast and filmmaking video cameras.
