Canon EOS R

The Canon EOS R is the first full-frame mirrorless interchangeable-lens camera (MILC) produced by Canon. It was announced days after Nikon's first full-frame MILC, the Nikon Z7, and five years after Sony's first, and was released in October 2018. The camera is the first of Canon's new EOS R system, and the first to use the RF lens mount. The "R" stands for "Reimagine optical excellence". The EOS R features a 30.3 megapixel CMOS sensor, an OLED viewfinder and an articulating LCD touchscreen. Autofocus uses dual-pixel technology, and "Eye Detection AF" automatically focuses on human faces within the scene. The mechanical shutter can capture still images at up to eight frames per second, and cropped-sensor 4K video capture is supported at 30 fps. The EOS R uniquely offers a "Multi-function Bar", a configurable touch-sensitive strip. The EOS R also introduced the "Flexible Priority Exposure" ("Fv") mode. Adapters are available to allow mounting of older lenses which require the EF lens mount. Canon also released an astrophotography variant named EOS Ra, which uses a modified IR cut-off filter to allow more H-alpha light to be captured, and offers stronger digital magnification, but is otherwise identical to the EOS R. The Canon EOS R was received with mixed reviews, and compared unfavourably to the Nikon Z6 and the Sony α7 III, though there was praise for the EOS R's autofocus and image quality, and for the RF lenses launched with it. The Multi-function Bar was roundly dismissed by critics as a failure. The EOS R was later unofficially discontinued and listed as "no longer in production" on the official Canon site.
