Canon EOS 77D Review

May 16, 2017 | Mark Goldstein | |

Image Quality

All of the sample images in this review were taken using the 24 megapixel Fine JPEG setting, which gives an average image size of around 7Mb.

The Canon EOS 77D produced images of excellent quality during the review period. This camera produces noise-free JPEG images from ISO 100 all the way up to ISO 1600, with noise first appearing at ISO 3200 - a very good performance for a 24 megapixel APS-C Sensor. The faster settings of 6400 and 12800 display progressively more noise, with the fastest settings of 25600 and 51200 best reserved for emergenices.

The night photograph was very good, with the maximum shutter speed of 30 seconds and Bulb mode allowing you to capture enough light in all situations. The different Picture Styles and the ability to create your own are a real benefit to JPEG shooters, as are the Highlight Tone Priority and Auto Lighting Optimizer custom settings when used in the right conditions. The HDR mode combines three images taken at different exposures to create a single image with greater dynamic range, while the Creative Filters allow you to preview the effect before shooting.

Noise

ISO sensitivity can be set between ISO 100 and ISO 12800 in full-stop increments, and a boosted setting of ISO 51200 is also available. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and the RAW equivalent on the right.

JPEG	RAW
ISO 100 (100% Crop)	ISO 100 (100% Crop)


ISO 200 (100% Crop)	ISO 200 (100% Crop)


ISO 400 (100% Crop)	ISO 400 (100% Crop)


ISO 800 (100% Crop)	ISO 800 (100% Crop)


ISO 1600 (100% Crop)	ISO 1600 (100% Crop)


ISO 3200 (100% Crop)	ISO 3200 (100% Crop)


ISO 6400 (100% Crop)	ISO 6400 (100% Crop)


ISO 12800 (100% Crop)	ISO 12800 (100% Crop)


ISO 25600 (100% Crop)	ISO 25600 (100% Crop)


ISO 51200 (100% Crop)	ISO 51200 (100% Crop)

File Quality

The Canon EOS 77D has 2 different JPEG file quality settings available, including Fine and Normal, with Fine being the higher quality option. Here are two 100% crops which show the quality of the two options.

Fine (7.16Mb) (100% Crop)	Normal (3.59Mb) (100% Crop)


RAW (28.7Mb) (100% Crop)

Flash

The flash settings on the Canon EOS 77D are Auto, Manual Flash On/Off, and Red-Eye Reduction. These shots of a white coloured wall were taken at a distance of 1m.

Flash Off - Wide Angle	Flash On - Wide Angle


Flash Off - Telephoto	Flash On - Telephoto

And here are a couple of portrait shots. As you can see, neither the Flash On setting nor the Red-Eye Reduction option caused any amount of red-eye.

Night

The Canon EOS 77D's maximum shutter speed is 30 seconds and there's a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 15 seconds, aperture of f/8 at ISO 100.

Picture Styles

Canon's Picture Styles are preset combinations of different sharpness, contrast, saturation and colour tone settings. The available Picture Styles are shown below in the following series, which demonstrates the differences. You can tweak these Picture Styles to your liking, and there are also User Defined styles so that you can create your own look.

Standard	Portrait


Landscape	Fine Detail


Neutral	Faithful


Monochrome

Creative Filters

Essentially a more extreme version of the well-established Picture Styles, Creative Filters offers 10 options, all of which can be interactively tweaked to suit your taste.

Grainy B/W	Soft Focus


Fish-eye Effect	Toy Camera Effect


Miniature Effect	Water Painting Effect


HDR Art Standard	HDR Art Vivid


HDR Art Bold	HDR Art Embossed

Auto Lighting Optimizer

Auto Lighting Optimizer performs in-camera processing to even out the contrast and correct brightness. There are 4 different settings - Off, Low, Standard and Strong.

Off	Low


Standard	High

Highlight Tone Priority

Highlight Tone Priority is a custom function which can be enabled from the menu. Use of this custom function improves highlight detail by expanding the camera's dynamic range in the highlights. As you can see from these examples, Highlight Tone Priority reduced the extent of highlight blow-out considerably.
