Canon's unified pro flagship DSLR — the EOS-1D X, 18MP full-frame, EF mount, 2011.
The Canon EOS-1D X, announced in 2011, unified Canon's previously split professional line by merging the speed-oriented 1D and the resolution-oriented 1Ds into a single full-frame flagship. It became the standard press and sports body for agencies and staff photographers through the mid-2010s.
This is a professional full-frame digital SLR with a sealed magnesium-alloy body and integrated vertical grip. It carries an 18-megapixel full-frame CMOS sensor, takes Canon EF-mount lenses, and uses an optical pentaprism viewfinder. Continuous shooting reaches around 12 frames per second mechanically, or higher in a locked-mirror mode. It records Full HD 1080p video, reflecting the early-2010s move to hybrid stills-and-video bodies.
The 1D X was built for sports, news and reportage professionals who prioritised speed, low-light performance and autofocus tracking over pixel count. The full-frame sensor and moderate resolution favoured high ISO cleanliness. Handling follows the 1-series pattern with dual grips and extensive weather sealing for stadium, sideline and field use.
Request the shutter actuation count against a rated life around 400,000 cycles, since these bodies saw heavy professional use. Inspect the sensor for dust and marks, test the rear screen and any dead pixels, and check card and battery door latches. The LP-E4N battery is still available but ageing examples lose capacity, so confirm charge retention and that a charger is included.
