The Canon EOS Rebel SL3 (EOS 250D in most regions) is an ultra-compact digital SLR that features a 24MP APS-C-sized CMOS sensor, DIGIC 8 processor and Dual Pixel autofocus system. The main differences between the SL3 and SL2 is the addition of Eye AF during live view, an even smaller and lighter body, and 4K video.
