Design and ergonomics
Measuring 139×105.2×78.5mm, the EOS 80D is a touch bigger than the EOS 77D, that camera shaving off a few mm here and here at 131.0×99.9×76.2mm. With its battery and card in place it’s also heavier too, weighing around 730g next to the EOS 77D’s 540g.
As a more substantial, mid-range option, it’s no great surprise that the EOS 80D also offers weather sealing, something that’s lacking from its newer sibling.
Around the back, the only difference of any significance is that the menu pad on the EOS 77D has direct access to specific functions (White Balance, Picture Styles and so on) while also offering a quick control dial around it. The EOS 80D adheres to the template set out by previous double-digit EOS models in not having options directly marked on the menu pad.
Perhaps the most significant changes between the two are on the top plate. While both bodies have been equipped with top-plate LCDs, Canon has been able to make the EOS 80D’s noticeably larger. There’s still a good deal of information contained with the EOS 77D’s screen, although its small size means it looks a little cramped.
There are also more direct controls in this area on the EOS 80D, with AF, metering and drive mode options in addition to the AF area selector, ISO and top-plate illuminator options present on the EOS 77D.
The EOS 77D and the EOS 80D each sport a 24.2MP APS-C CMOS sensor, and both of these have phase-detect pixels incorporated into their design. This means that both can offer Canon’s Dual Pixel CMOS AF system for live view and video focusing, although they also share the same 45-point AF system when using the viewfinder.
We shouldn’t expect image quality to be entirely the same however, as there is a difference in processing. The EOS 80D pairs its sensor with Canon’s DIGIC 6 processor, but the newer EOS 77D employs the more up-to-date DIGIC 7 engine. Canon claims this has helped to improve noise performance at higher ISOs and also subject tracking among other things.
This combination also means that there’s a full stop difference in terms of available ISO settings. Whereas the EOS 80D spans a native range of ISO 100-12,800 and finishes this off with an expansion equivalent to ISO 25,600, the EOS 77D runs from ISO 100-25,600 as standard and offers an ISO 51,200-equivalent setting on top of this.
Its 7fps burst speed is also a frame-per-second faster than the 6fps offered by the EOS 77D, although, possibly thanks to the new processor, the EOS 77D can carry on shooting JPEGs until the card is full, unlike the EOS 80D which can only last for 110 frames.
Other advantages of the EOS 80D include a pentaprism viewfinder with approx. 100% frame coverage and 0.9x magnification, next to the EOS 77D’s pentamirror viewfinder with 95% coverage and 0.82x magnification. The EOS 77D’s viewfinder also has an eye sensor, something that the EOS 80D does not offer.
Both cameras are reasonably equal when it comes to their video specs, and neither offers 4K shooting, but there are differences.
Both capture Full HD video up to 60fps and work with lens-based image stabilisation systems to help keep images sharp and videos steady, but the newer EOS 77D boasts a five-axis Digital IS system too.
This helps stabilise video footage when a non-stabilised lens is used, although it can also work in conjunction with lens-based IS systems.
With its stronger battery life, better viewfinder, weather-resistant design and faster burst rate, the EOS 80D is likely to appeal to those after a camera for sports and action photography, and just generally for outdoor use. Its higher maximum shutter speed also makes using the EOS 80D with wider-aperture lenses in bright sunlight easier.

While the EOS 77D is perhaps aimed at a less demanding audience, it does have a handful advantages. It’s smaller and significantly lighter, with a newer processing engine on board and a broader ISO range. As such, out of the two, it’s possibly the option with wider appeal.
