Canon EOS Rebel T4i photo samples

The T4i's noise profile is pretty good, though like many cameras it fares a lot better in focused areas than out-of-focus ones. Here, it preserves clean detail until about ISO 400, at which point it starts to degrade.

The camera does a reasonable job of resolving detail and rendering sharp images without looking oversharpened.

(1/125 sec, f5.6, ISO 100, spot metering, AWB, 18-135mm lens at 116mm)

This looks just a little more processed and mushy than I'd like for such a low ISO sensitivity setting.

(1/125 sec, f7.1, ISO 200, evaluative metering, AWB, 18-135mm lens at 35mm)

The JPEG version looks comparatively good until you look at edge details like the windowsills.

(1/80 sec, f1.8, ISO 800, spot metering, AWB, 24mm f1.4 lens)

Color settings differences aside -- and this is one case where I like the deeper tones produced by the default Auto Picture Style -- you can do better processing the raws at ISO 800 (bottom) than with the JPEGs (top).

(1/80 sec, f1.4, ISO 800, evaluative metering, AWB, 24mm f1.4 lens)

As with most cameras, in-focus areas at high ISO sensitivities look pretty good, but out-of-focus areas display lots of artifacts, including hot pixels.

(1/50 sec, f2.2, ISO 1600, evaluative metering, AWB, 24mm f1.4 lens)

The T4i fares worse than the T3i at higher ISO sensitivities, either because of lower sensor response or in-camera overprocessing of the blue channel.

(1/30 sec, f3.5, ISO 1600, spot metering, AWB, T4i: 18-135mm lens at 19mm; T3i 18-55mm lens at 18mm )

Although you can see the noise when you pixel peep, even at ISO 3200 the images are usable if there aren't a lot of shadow areas in them.

(1/60 sec, f2.2, ISO 3200, evaluative metering, AWB, 50mm f1.2 lens)

You can still get reasonable detail and texture as high as ISO 6400.

(1/30 sec, f4, ISO 6400, spot metering, AWB, 18-135mm lens at 29mm)

The camera produces exceptionally saturated, contrasty photos on its default setting.

The default Auto Picture Style really pushes the contrast and saturation to the point where hues shift slightly and you start to lose shadow detail.

(1/100 sec, f6.3, ISO 100, evaluative metering, AWB, 18-135mm lens at 35mm)

Blown out detail in bright, saturated hues can usually be recovered within the raw file.
