The EOS 4000D inherits an aging 18MP sensor that can trace its roots back to the EOS 550D, which was released in 2010. The latest tech this is not. 

It's a similar story with the DIGIC 4+ image processor used in both the EOS 4000D and EOS 2000D. To put it in perspective, we're now onto the eighth iteration of Canon's DIGIC processor, although the latest EOS DSLRs are using DIGIC 7 chips. Native sensitivity remains the same at ISO100-6,400, 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.
