The Canon Extender EF lenses are a group of teleconverter lenses made by Canon. These lenses are used between any compatible EF type lens and any of the Canon EOS line of cameras. When used with a compatible lens, they will multiply the focal length of the lens by a factor of either 1.4x or 2x, at the cost of decreasing the lens' aperture by 1 ...
He ported it to the Canon EOS 550D in July 2010. There are now versions for many other Canon DSLRs and the current principal developer is known as A1ex. Since installing Magic Lantern does not replace the stock Canon firmware or modify the ROM but rather runs alongside it, [3] it is both easy to remove and carries little risk. [4]
Canon printers are supplied with Canon Advanced Printing Technology (CAPT), a printer driver software stack developed by Canon. The company claims that its use of data compression reduces their printer's memory requirement, good quality compared to conventional laser printers, and also claim that it increases the data transfer rate when ...
That lens was the Canon EF 8-15mm f/4L Fisheye USM. Canon in 2012 made the first wide angle lens with Image Stabilization. That lens was the Canon EF 24mm f/2.8 IS USM.

The gold-plated electronic contacts of an EF-mount lens. Canon introduced the EF-lens mount in 1987 as part of the EOS system. It broke with the most common technique for implementing autofocus at that time by not having a mechanical connection to a motor in the camera body, having instead only electrical connections and requiring a motor to be ...

Canon New FD lens mounting surface.. The FD lens mount is a breech-lock mount, which is a variation of the common triple-flanged bayonet attachment. The advantage of the breech-lock over the bayonet is that neither the contact surfaces between the body and lens, nor the signalling mechanisms, rotate against each other when the lens is mounted.
The EF 1200 mm f / 5.6 L USM is a super-telephoto prime lens that was made by Canon Inc. It uses an EF mount, and is compatible with the Canon EOS camera range. It has a focal length of 1200 mm and so on a digital body with a sensor size of 22.5 mm × 15 mm (called 1.6× crop), such as a Canon EOS 40D or 450D, it provides a 35 mm field of view equivalent to that of a 1920 mm lens.
