Canon 77D vs Canon 80D: what are the key differences?

While they have a lot in common, there are a few key differences between the new Canon 77D and the Canon 80D that sits just above it in Canon’s DSLR line-up. Let’s take a look at how they compare:

Canon 77D vs Canon 80D: Sensor

Although they have the same 24.2 million pixel count, according to Canon, the sensor in the 77D is different from the one in the 80D. Canon isn’t going into detail about what the differences are, but we’re told that the new device boosts the 77D’s speed and image quality.

Canon 77D vs Canon 80D: Processor

The Canon 80D has the Digic 6 processing engine but the Canon 77D has the newer Digic 7 engine.

Canon 77D vs Canon 80D: Sensitivity range

Thanks to the new sensor and Digic 7 processing engine the 77D has a native sensitivity range of ISO 100-25600, this can be expanded up to ISO 51,200. Meanwhile the older 80D’s sensitivity range is ISO 100-16,000 expandable to ISO 25,600. This should make the 77D just a little better in low light.

Canon 77D vs Canon 80D: Continuous shooting rate

Despite the fact that the Canon 77D has a Digic 7 processing engine, its maximum continuous shooting speed is 6fps, 1fps lower than the 80D. I suspect that Canon has reined in the 77D a little here to give some separation between it and the 80D above it.

Things are a bit different with the burst depth though as the 77D can shoot at up to 6fps until the card is full with jpegs or for 27 raw files. Meanwhile the 80D can maintain its 7fps rate for up to 110 jpegs or 25 raw files, that’s a major drop in the jpeg burst depth.

Although you can shoot at a fast rate for far longer with the 77D, you’d have to shoot for nearly 16 seconds at 7fps to fill the 80D’s buffer with jpegs. If you opt for raw files you have just 3.6 seconds of shooting with the 80D and 4.5 with the 77D (albeit at a lower rate).

Canon 77D vs Canon 80D: Size and weight

The Canon 77D is billed as the smaller, lighter alternative to the 80D. Including the battery and memory card it weighs 540g, that’s 190g less than the 80D. That’s a weight saving of about 26%.

According to the spec sheet, the 77D measures 131.0 x 99.9 x 76.2mm while the 80D is 139 x 105.2 x 78.5mm, making the 77D smaller in every dimension.

Canon 77D vs Canon 80D: Battery Life

The Canon 80D has a larger battery with considerably longer life, 960 shots vs 600.

The Canon 77D’s battery life is listed as:

Using the viewfinder: Approx. 600 (at 23°C)
Using the viewfinder: Approx. 550 (at 0°C)
Using live view: Approve 270 (at 23°C)
Using live view: Approve 230 (at 0°C)

While Canon lists the 80D’s battery life as:

Approx. 960 (at 23°C)
Approx. 860 (at 0°C) – Presumably both these figures are for when the viewfinder is used to compose images.
