Advanced Photo System type H - APS-H dslr

APS-H sensor has a crop factor of 1.3x, so a 50mm lens is equivalent to a 65mm lens on FF. The crop factor is excellent for those who want to get closer to their subject without spending money on a more expensive lens, but its also bad news for those who want as much as possible on their photograph without buying a wider lens
.

A Full Frame camera would get you the entire picture above, while APS-H with the same lens would give only whats inside the blue box. If your main focus is sports and action, then APS-C would probably be better as it allows you to get even closer to your subject!
Crop Factor: 1.3x
Sensor Size: 28.7 x 19mm (Full Frame is 36 x 24mm)

Does Canon still use APS-H in DSLR cameras?

No, and most likely never again will.
The first Canon to feature APS-H was the Canon EOS-1D, a camera that greatly influenced all later sports/action cameras. At that time, full frame sensors were quite expensive to make, and a 1.3x smaller sensor would result in a cheaper, smaller body.

While the APS-H format was reserved for 1D line, the APS-C was widely used in all Canons entry-level cameras, and also had a lens mount for it (EF-S mount), something that APS-H never had.

When did the APS-H format go away? In 2011, when Canon announced the EOS-1D X, a full frame camera with features perfect for both action and still photography.
