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 move from Canon’s aging 18.0-megapixel sensor used in the 700D to this new 24.2MP CMOS device hasn’t just given the 750D a much needed specification boost, it also translates to superb image quality. You’ll struggle to see a difference between ISO 100 and 400 shots, and there’s only a negligible reduction in fine detail at ISO 800. At ISO 1600 there’s a slight increase in grain and a few subtle instances of colour speckling can be spotted on neutral tones if you examine very closely. ISO 3200 images display a little more grain and a little less detail, but again, the quality reduction is impressively small. It’s a similar story at ISO 6400 and ISO 12800, as each setting introduces only marginally more noise, plus a slight increase in detail smoothing and colour boundary smearing. At ISO 12800 there’s also some blotchiness in areas of solid tones, but only to a degree you’d normally expect from an ISO 3200 shot.

Even without scrutinising, images from the Canon EOS 750D are impressive. With the Picture Control colour options set to ‘Standard’, colours are vibrant without looking oversaturated or unnatural. The camera’s evaluative exposure metering is also extremely reliable, and though it shares the same 63-zone system as the 700D, there’s now a 7560-pixel RGB sensor to account for colour as well as light approaching the infra-red spectrum.

You’re rewarded with images that are almost always accurately exposed and display an ideal balance of highlight and shadow detail. In order to achieve bright overall exposures in high-contrast conditions, some highlight details can blow out, but this is rare and easily overcome by exploiting the camera’s HDR mode.

Although our EF-S 17-85mm f/4-5.6 IS USM test lens isn’t Canon’s sharpest optic, it was good enough to demonstrate the Canon EOS 750D’s ability to resolve plenty of fine detail. Sharpness can be adjusted along with parameters like contrast, saturation and colour tone in the camera’s Picture Style options. Images also respond well to sharpening in Photoshop, thanks to their low levels of grain noise.

Noise

The Canon EOS 750D has eight sensitivity settings ranging from ISO 100 to 12800. This can be expanded one stop to add a High (ISO 25600) sensitivity by enabling ‘ISO expansion’ via the main menu. The camera’s auto ISO upper limit can also be configured, with a maximum sensitivity of ISO 6400. However, the 750D’s sensitivity scale only changes in 1EV steps and there’s no option to add 1/3EV increments. It’s worth noting that our ISO test run was first shot with high ISO noise reduction set to Standard. With the system turned off, noise does become more apparent from ISO3200 upwards, though fine detail is slightly clearer. Whether you choose to shoot with the system enabled and add some sharpening in post-production, or disable in-camera noise reduction and apply your own later is likely to yield very similar end results.

File Quality

Numerous file quality and size options are available. At full 24.2MP resolution you can shoot in raw (approx. 30MB file size), JPEG Fine (6-12MB) and JPEG Normal (3-6MB). There’s also a raw+JPEG Fine setting.

The medium (M) image size translates to 11MP (3984x2656) photos, with Fine and Normal compression options available. Selecting the ‘S1’ image size gives 5.9MP images at 2976x1984 resolution, again with Fine (~2MB file size) and Normal (~1MB) compression options. S2 image size results in 1920x1280 shots, also around 1MB in size. Finally, the ‘S3’ option generates 720x480 shots which consume less than 500KB of card space.

Sharpening

The out-of-camera JPEGs are quite soft and at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level to suit your tastes via the Picture Style options.

Flash

Options for the built-in flash are controlled via the Quick Control menu and also the main menu. Three flash choices are available via Quick Control: Normal flash firing, Easy wireless flash and Custom wireless flash. Red-eye reduction is enabled or disabled from the first page of the main menu, as are more advanced options such as TTL metering modes, flash sync speeds and flash exposure compensation.

Flash On - Wide Angle (29mm)

Whether red-eye reduction is enabled or not, the 750D successfully avoided red-eye during our testing. The flash was also able to evenly illuminate a white surface from a distance of 1.5 meters with no vignetting at a 17mm focal length.

Night

Another of the Canon EOS 750D’s six scene modes is Handheld Night Scene. This works in a similar way to the HDR Backlight Control mode, with the camera capturing multiple frames and compiling them into a single image. In our case the final image was recorded at ISO 6400, so we shot the same scene at this sensitivity using regular Program Auto mode for comparison.

Clearly Canon’s trickery does make a difference, as the Handheld Night Scene image displays noticeably less noise at the same recorded sensitivity, and though it’s marginally softer than the Program Auto shot, the overall appearance is better.

Of course if you want maximum low light image quality, a long exposure from a tripod is the only way to go. Nevertheless, the quality difference between our 1-second ISO 400 long exposure and the Handheld Night Scene image is impressively small.

Creative Filters

Although DSLR’s aren’t really about filter effects, the entry-level nature of the 750D means Canon has seen fit to include seven effects. These can be applied live as you shoot, providing you’re not shooting in raw or raw+JPEG modes. They can also be added to existing shots in playback mode. The effects are: Soft focus, Fish-eye effect, Art bold effect, Water painting effect, Toy camera effect & Miniature effect.

HDR Backlight

One of the most useful of the Canon EOS 750D’s half-dozen scene modes is HDR Backlight Control. Here the camera fires three consecutive shots to capture highlight, mid-tone and shadow detail, then combines them automatically into an image with far better dynamic range than a single exposure. The process is fast and the results look seamless and fairly natural.
