The 800d is built around a 24.2-megapixel aps-c cmos sensor – as used inside the more advanced 80d (£840 body-only). While the 750d/760d also sported 24.2-megapixel sensors, neither encompasses canon’s dual pixel af technology, so while effective resolution remains identical to the 800d’s sensor, it represents a fairly big step forward.
Likewise, the 800d also employs canon’s latest generation digic 7 image processor, as opposed to the digic 6 chip found inside the 750d/760d. Canon claims that the digic 7 is able to process data 14x faster than its predecessor, which not only enables the 800d to provide a higher maximum burst speed of 6fps (compared to 5fps on the 750d/760d), but also to fire off a higher number of consecutive images when burst shooting.
In addition, the new sensor and processor pairing also allows the 800d to offer a higher maximum native sensitivity setting of iso 25,600, along with the equivalent of iso 51,200 in expanded mode. By way of comparison, the 750d
