35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
A new version of the lens, the f/3.5–5.6 IS STM, was announced on 8 June 2012, alongside the EOS 650D/Rebel T4i/Kiss X6i.The "STM" stands for "Stepping Motor", a new autofocus technology claimed by Canon "to smoothly and silently focus" and "achieve continuous AF while recording video" when used with the 650D (and presumably future Canon bodies).

The EF 35mm f / 1.4L II USM is a successor of the EF 35mm f / 1.4L USM. It was announced at the 27th of August 2015 and is available since October same year. [1] The EF 35mm f / 1.4L II USM lens is the first lens in Canon line up to use a Blue Spectrum Refractive Optics element (BR element) to reduce the chromatic aberration at the blue end of the spectrum.

Canon PowerShot N100, has also rear-facing lens as smartphone, but front and rear lenses both together will take photo/video when the shutter is pressed and the rear lens image will appear in the corner of the big image from front lens as picture-in-picture, so the camera is called as a 'Story Camera' [5]
The Canon EF-S 10–22mm f / 3.5–4.5 USM lens is a wide to ultra-wide angle zoom lens for Canon digital single-lens reflex cameras with a Canon EF-S lens mount. [1] The field of view has a 35 mm equivalent focal length of 16–35mm, which is analogous to the EF 16–35mm f / 2.8L on a full-frame camera. The 10–22mm is an internal focusing lens.
For example, a 35 mm lens mounted on a full-frame Canon EOS 5D provides a slightly wide-angle view, while the same lens mounted on an APS-C Canon EOS 400D provides a "normal" or slightly telephoto view. In order to more easily compare lens–camera pairs, it is common to use their 35 mm equivalent focal length.
Enter the Canon Pixma MG2522 all-in-one, currently on sale at Walmart for just $29. You'd be hard-pressed to buy a single ink cartridge for $29, let alone an entire printer.
As it is designed for Canon APS-C bodies, its field of view is equivalent to a 38mm lens on a full-frame sensor, and operates similar to the Canon EF 40mm f/2.8 STM pancake lens. Compared to the EF 24 f / 2.8 IS USM, the EF-S lens loses IS, but lists for about a fourth of the price.
