With most of the EOS Rebel T100 / EOS 4000D made up of components from the parts bin for long-superseded Canon DSLRs, there's really nothing much to recommend this camera over rival entry-level DSLRs, apart, perhaps, from the price.
Easy to use, Logically laid-out controls, Decent battery life, Low price
Dated 9-point AF, Small and low-resolution screen, Only 3fps burst shooting, Plastic finish and lens mount, No touchscreen
