I have been looking for a camera and/or software that will stich photos horizontally and vertically. I have seen what is possibly out dated info on Canon eos cameras coming with Photostitch software. is this still true. and what does eos stand for. I am writing a book and cannot proceed without improving my photography. please advise if possible. Paul

EOS = Electro-Optical System

My newest camera is a 1D Mk IV and it came with Photostitch. But it is several years old as have not got the 1Dx bug.....yet !

I bet you can d/l Photostitch from Canon. I use Photoshop so I really don't know much about Photostitich.

BTW, Eos was the goddess of the dawn in mythology. Some say that is where it came from. Some people say Eos as a name but others say E-O-S as initals.

Yes, PhotoStitch is still included with the cameras. As I look at th Canon software updates available for my camera (my most recent is the 5D III) I see that they updated PhotoStitch to version 3.2.7 as recently as a month ago (7/30/2014).

You dont' have to use Canon's stitching software... there are other photo editing tools that can do this as well.

As ebiggs points out... it's Electro-Optical System.

Prior to EOS, Canon 35mm film cameras used a mechanical interface between the camera body and lens to control lens aperture blades and the lenses were not auto-focusing (there were some experimental lenses that did). EOS added auto-focus sensors to the camera body with an electronic interface to the lens to control the aperture blades as well as auto-focus motors in the lens. Nearly all EOS lenses are auto-focusing lenses. There are some specialty lenses which do not support auto-focus such as the tilt-shift lenses (tilt-shift / perspective-control lenses in general (from any manufacturer) to not support auto-focus) and the MP-E (a special "extreme" macro-photo lens.) To my knowledge, all other EOS lenses provide auto-focus.

The same EOS lenses used in the film cameras also work on Canon EOS digital cameras.
