The canon eos 4000d features a 18mp sensor that can be traced back to the eos 550d / eos rebel t2i which was released in 2010. In perspective, we're now onto the eighth iteration of canon's digic processor, although the latest eos dslrs are using digic 7 chips. It's native sensitivity is at iso100-6,400, and expandable up to 12,800.
The autofocus system is also pretty dated, it's the modest 9-point system that has been in canon's arsenal since 2009. And while pretty much every dslr in the last five years or so has featured a 3.0-inch rear display, canon has actually shrunk the lcd on the eos 4000d down to 2.7 inches, with the resolution also taking a tumble, down to 230k dots. And don't even think about touchscreen control.
The optical viewfinder delivers 95% coverage, which is pretty typical on a entry-level dslr. There's wi-fi connectivity, but no nfc or bluetooth low energy options, while video is capped at full hd (1920 x 1080), with 30, 25 and 24fps frame rates available
