Summary. The Canon EOS 4000D is the most budget-friendly Canon DSLR and features an 18MP APS-C-size sensor. It uses Canon's DIGIC 4+ image processor which offers an ISO range of 100-6400, expandable to 12800, as well as 3 fps burst shooting. It features a 9-point AF system with a cross-type sensor at the center.As a photography camera, it's an okay entry-level model for the price, with a decent sensor, a passable autofocus system, and plenty of great, affordable lens options, but its cheap price tag comes through in its plasticky build quality and low-resolution screen.
