Canon Eos (Electro-Optical System) is a 35mm Slr camera introduced by Canon in 1987 and currently in use, built nearby attacking Canon Ef. It replaces the former principles built nearby attacking Canon Fd.
The Eos principles includes autofocus 35mm Slr cameras and digital format 24x36, Aps-H and Aps-C. The first was the Canon Eos camera Eos 650. The acronym Eos was chosen in reference to Greek mythology, where the name Eos is the goddess of dawn. It is often pronounced as one word, although it is equally exact to spell personel letters since both rulings make sense logically.
From the commercial point of view, the Canon Eos principles is in direct competition with the Nikon F series and its subsequent developments, as well as autofocus Slr systems products by Olympus, Pentax, Sony / Minolta and Panasonic / Leica. In many countries, the Eos cameras have captured the shop share larger than its competitors.
The heart of the Eos principles is the Ef bayonet which supplanted the aforementioned graft Fd. The reasons for this rotation are in general associated to the introduction autofocus in the second half of the eighties of the twentieth century. This new technology, marketed by Minolta in 1985, led Canon to implement manufacture an charge from scratch, instead of modifying the graft Fd, similar to what has been done by Minolta in 1985 and unlike Nikon decided that instead of update its thirty bayonet F. This choice, though risky, was repaid by the superiority that the principles created from scratch knew vouch for competing systems. Bold originate choices such as built-in motor lens and exclusive patents supply an perfect autofocus and unmatched by other brands so that in the middle of the late eighties and nineties of the twentieth century, the majority of professional photographers went to the Canon system. At the end of the twentieth century, the originate religious doctrine inaugurated by the Canon Eos principles had become approved even among all the other 35mm Slr manufacturers.
