Bryan at The-Digital-Picture has completed his review of the Canon EOS 77D. In true Canon fashion, it's not a segment leader on the spec sheet, but it's definitely a DSLR you should consider if your budget for a body is around $900.
The 77D is positioned mid-level, as step up from the Rebel series cameras, yet remaining decidedly below the 80D in Canon's lineup, targeting moderately serious non-professional photographers. While I'm sure that Canon is trying to better differentiate this model from the Rebels, it is still primarily a Rebel in my mind. It has the same size and shape along with nearly identical features as the announced-at-the-same-time Rebel T7i. However, the few feature differentiators are valuable, making it a better choice for most photographers – as long as the higher price tag does not trip up this decision.
From an upgrade perspective, the pair of new AF systems (45 pt traditional phase detection system and Dual Pixel AF system) alone make the 77D a great upgrade from the Rebel T6s. A faster frame rate and greatly increased RAW image buffer depth are also very-welcomed improvements. Read the full review
