Canon EF-M Lens Mount
The Canon EF-M lens mount, introduced in 2012, was a derivative of the Canon EF lens mount designed for use with the Canon EOS M mirrorless interchangeable-lens camera. The EF-M lens mount is one of Canon's two systems for mirrorless cameras, the other being the RF mount. The M system has an 18 mm flange focal distance (compared to 20 mm for RF and 44 mm for EF and EF-S) and a 47 mm throat diameter (compared to 54 mm for EF, EF-S, and RF). As it is designed for use with an APS-C-sized image sensor, it features the same crop factor In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital ... (of roughly 1.6) as the existing EF-S lens mount. The M system was somewhat limited as Canon had only released 8 native lenses, listed below. There was a lack of native lenses ...

Canon EF Lens Mount
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a Bayonet mount, bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount was first introduced in 1987. Canon claims to have produced its 100-millionth EF-series interchangeable lens on April 22, 2014. History The EF mount replaces its predecessor, the Canon FD, FD mount. The standard autofocus lens mounting technology of the time used a motor in the camera body to drive the mechanics of the focus helicoid in the lens by using a transfer lever. The key innovation of the EF series was to use a motor inside the lens itself for focusing. This allowed for autofocusing lenses which did not require mechanical levers in the mount mechani ...

Canon EOS M100
The Canon EOS M100 is a digital mirrorless interchangeable-lens camera first announced by Canon Inc. on August 29, 2017. Canon EOS M100 incorporates the proprietary image processor that allows the camera to capture still images up to 6.1 fps using the fixed focus and 4 fps burst mode. The EOS M100 can be connected to all EF, EF-S and TS-E lenses with an available adapter. Design The EOS M100 is an interchangeable lens camera that uses the Canon EF-M lens mount. The EOS M100 is an entry-level model which lacks the large rubber grip, multiple control dials, and hot shoe flash that can be found on the larger and more expensive Canon EOS M6. The EOS M100 uses the same 24.2 MP APS-C sensor as the Canon EOS M6. The EOS M100 also uses the Dual Pixel CMOS autofocus system. However, unlike the EOS M10, the EOS M100 features the same DIGIC 7 image processor as the newer Canon EOS M6. The camera supports uncompressed 1080p video. The camera has in-camera RAW conve ...

Macro Photography
Macro photography (or photomacrography or macrography, and sometimes macrophotography) is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life-size (though ''macrophotography'' also refers to the art of making very large photographs). By the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life-size or greater. In some senses, however, it refers to a finished photograph of a subject that is greater than life-size. The ratio of the subject size on the film plane (or sensor plane) to the actual subject size is known as the reproduction ratio. Likewise, a macro lens is classically a lens capable of reproduction ratios of at least 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1. Apart from technical photography and film-based processes, where th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
