With a newer 24MP APS-C sensor and faster DIGIC 7 processor, the Canon 77D is the successor to the Rebel T6s, despite the change in naming, and stacks up to be Canon’s top-of-the-line entry-level DSLR. As expected, the image quality overall is very good, with nice detail and pleasing color.

Dynamic range at low ISOs has been increased, and high ISO performance is slightly improved, though both still lag behind some competitors. The 77D also features an upgraded 45-point autofocus system as well as Dual Pixel CMOS AF, plus faster burst shooting and a much bigger RAW buffer. Like its predecessor, the 77D combines the ease-of-use of an entry-level DSLR with more advanced controls typically seen on higher-end DSLRs. It’s a versatile camera for those looking to go beyond a basic DSLR yet don’t want to break the bank.

Below are crops from our laboratory Still Life target comparing the Canon 77D’s image quality to its predecessor’s, the T6s, as well as against several competing APS-C models — and one full-frame camera for good measure — which all sit at similar price points or product categories: the Nikon D5600, Pentax K-3 II, Sony A6300 and Sony A7. (You may be wondering why we included higher-end models like the Pentax K-3 II and full-frame Sony A7 in the mix; the reason is at the time of writing they are priced very similarly to the 77D.)

NOTE: These images are from best quality JPEGs straight out of the camera, at default settings including noise reduction and using the camera’s actual base ISO (not extended ISO settings). All cameras in this comparison were shot with our very sharp reference lenses. Clicking any crop will take you to a carrier page where you can click once again to access the full resolution image as delivered straight from the camera. For those interested in working with the RAW files involved: click these links to visit each camera’s respective sample image thumbnail page: Canon 77D, Canon T6s, Nikon D5600, Pentax K-3 II, Sony A6300 and Sony A7 — links to the RAW files appear beneath those for the JPEG images, wherever we have them. And remember, you can always go to our world-renowned Comparometer to compare the Canon 77D to any camera we’ve ever tested!

Canon T6s at ISO 100

Here, we compare the 77D to its true predecessor, the T6s. Both use a 24-megapixel APS-C sensor with optical low-pass filter, although the 77D’s sensor appears to be tweaked. The 77D uses a newer processor as well, the DIGIC 7 versus DIGIC 6 for the T6s. As you can see above, image quality at base ISO has changed little, with just slight differences in color and contrast. The T6s appears to do a bit better with our tricky red-leaf fabric, though.

Canon 77D at ISO 100
Nikon D5600 at ISO 100

While both cameras here feature 24-megapixel APS-C sensors, the Nikon D5600’s sensor lacks an optical low-pass filter, unlike the 77D’s. This, along with different approaches to default sharpening and noise reduction, allow the D5600 to produce a much crisper image than the 77D here in this base ISO comparison. Sharpening halos are obvious from both cameras, but the Nikon uses a slightly smaller radius with higher contrast. Noise in flatter areas is a bit higher from the Nikon as well.

Pentax K-3 II at ISO 100

Above we compare the 77D to another 24-megapixel APS-C DSLR, the Pentax K-3 II. The K-3 II is in a higher class, however it is currently selling for not much more than the 77D, so we decided to include it. The Pentax features an on-demand anti-aliasing filter, which has been turned off for maximum sharpness in these shots. As you can see, like the Nikon, the Pentax produces a sharper, more detailed image with fewer sharpening artifacts, however noise is a little higher, contrast is a little lower, and colors are less accurate than the Canon.

Canon 77D vs Sony A6300 at Base ISO

Canon 77D at ISO 100
Sony A6300 at ISO 100

Although we believe the Sony A6300’s 24-megapixel APS-C sensor has an optical low-pass filter, it must be a fairly weak one. Again, the big difference is in processing, as the Sony’s default sharpening is so much better than the Canon’s, producing a crisper, more detailed image with almost no sharpening artifacts and lower noise. We still prefer the color from the Canon better, though, as it has much less of a yellow to green shift, and is generally more vibrant as well.

Canon 77D vs Sony A7 at Base ISO

Sony A7 at ISO 100

Some may think a comparison to a full-frame camera really isn’t fair, but the 24-megapixel Sony A7 is selling for the exact same price at the time of writing, so we decided to include it anyway. As you can see, the Sony A7 already outperforms the 77D here at base ISO, with better sharpness, more detail, lower noise and fewer artifacts, and the difference will become even more apparent as ISO rises. Moiré patterns in the red-leaf swatch are however more visible from the A7, but that will vary with distance, lens, focus and subject matter so we won’t hold that against the Sony here as it has an optical low-pass filter as well.

Canon T6s at ISO 1600

Generally very similar image quality here at ISO 1600 from the two siblings, with just slight improvements to color, contrast and noise from the 77D, however the T6s holds on to noticeably more detail in our tricky red-leaf fabric.

Canon 77D vs Nikon D5600 at ISO 1600

The D5600 continues to deliver a much crisper image with better fine detail and similar noise levels in flatter areas here at ISO 1600, however the 77D does noticeably better in our troublesome red-leaf swatch.

Canon 77D at ISO 1600
Pentax K-3 II at ISO 1600

Here at ISO 1600, the K-3 II delivers a slightly sharper image with better detail (except in our read-leaf swatch), along with fewer noise reduction artifacts, however noise is a bit higher, particularly in dark areas. Color and contrast continue to be more pleasing from the Canon.

Canon 77D vs Sony A6300 at ISO 1600

Sony A6300 at ISO 1600

Apart from color, the A6300 easily comes out ahead here, with a much sharper, crisper image with better detail. Noise is lower as well, though the Sony’s noise “grain” isn’t quite as regular and film-like as the Canon’s.

Canon 77D vs Sony A7 at ISO 1600

Canon 77D at ISO 1600
Sony A7 at ISO 1600

As expected, there’s no contest here at ISO 1600 between the APS-C 77D and full-frame A7, though artifacts from the A7’s noise reduction do look a bit unnatural in flatter areas.

Canon 77D vs Canon T6s at ISO 3200

Again, just minor improvements in noise handling, contrast and color here at ISO 3200 over its predecessor.

Canon 77D at ISO 3200
Nikon D5600 at ISO 3200

The D5600 continues to deliver a sharper, crisper image with slightly better detail and contrast in most areas here at ISO 3200 , however sharpening halos are much more visible.

Canon 77D vs Pentax K-3 II at ISO 3200

Canon 77D at ISO 3200
Pentax K-3 II at ISO 3200

Similar to what we saw at ISO 1600, the Pentax K-3 II’s image at ISO 3200 contains more detail, but luminance noise is also much more visible and not as uniform as the Canon’s. Almost all detail is lost by the Pentax in our red-leaf swatch, while the 77D manages to produce a more reasonable facsimile. Color also remains much better from the Canon.

Canon 77D at ISO 3200
Sony A6300 at ISO 3200

The Sony A6300 continues to produce a crisper, more detailed image than the 77D at ISO 3200, however its area-specific noise reduction generates more artifacts in flatter areas and along edges than Canon’s more traditional approach to noise reduction. The 77D blurs our tricky red-leaf fabric quite a bit at ISO 3200, but much of the Sony’s apparent detail in that fabric is false.

Canon 77D vs Sony A7 at ISO 3200
100% crop from Canon 77D test image taken at ISO 3200 100% crop from Sony A7 test image taken at ISO 3200

Unsurprisingly, still no contest here, with the full-frame A7 producing a much cleaner, crisper, much more detailed image but with a more processed look to flatter areas.

Detail comparison. High-contrast detail is also important, pushing the camera in different ways, so we like to look at it separately here. As you can see, the 77D starts out with higher contrast than the T6s, but more importantly image quality doesn’t drop off as much as the T6s’ as ISO climbs. The D5600 is very crisp and detailed across all three ISOs, however sharpening halos are the most intrusive of the bunch. The Pentax K-3 II lags in contrast at base ISO but detail is very good, however image quality does fall off more than most of the others as ISO climbs. The Sony A6300 does very well, offering excellent detail and contrast with few sharpening halos and little drop-off in quality as sensitivity is increased. The full-frame Sony A7 is of course the winner here, offering the best detail and contrast across all three ISOs.
