Camera Overview — Canon EOS M3

The Canon EOS M3 is a compact mirrorless camera built around a 24.2MP APS-C sensor paired with Canon's DIGIC 6 image processor. It offers a native ISO range of 100 to 12800, giving photographers reasonable flexibility across a variety of lighting conditions. The hybrid autofocus system combines phase-detection and contrast-detection methods across 49 focus points, with subject tracking support and Face Detection AF — a useful set of tools for shooting people and moving subjects.

Burst shooting is available at up to 4.2 frames per second, which covers casual action photography adequately. On the video side, the M3 captures Full HD 1080p footage at up to 30fps, with frame rate options of 24fps, 25fps, and 30fps recorded in 8-bit color. The color profile selection — including Standard, Portrait, Landscape, Neutral, Faithful, and Monochrome — applies to both stills and video.

A 3.0-inch LCD with 1040k-dot resolution handles composition, as there is no built-in viewfinder. The body is constructed from polycarbonate, measures 110.9 x 68 x 44.4 mm, and weighs 366g. Connectivity includes Wi-Fi, Mini HDMI output, a 3.5mm microphone jack, and a standard USB port.

The camera uses the Canon EF-M lens mount and accepts SD, SDHC, and SDXC memory cards. A built-in flash and Canon Standard TTL hot shoe are also present. The LP-E17 battery is rated for approximately 250 shots per charge.
