Performance Not surprisingly, the performance of the review camera was similar to that of the EOS 7D we reviewed last November which came with the same kit lens. Still pictures were sharp and colourful, although saturation was slightly higher with the D, particularly for reds.

HD video quality was outstanding, particularly at p resolution with the 24 fps frame rate. There was a visible difference between the p and p video clips and between the HD and SD video. Clips shot in the VGA Crop mode were soft and noticeably lower-quality. However, audio quality from the built-in microphone was well above average. Low-light autofocusing was generally very good — and noticeably better than the EOS 7D we tested.

Note: the same lens was used for testing both cameras. The graph below shows the results of our tests based on this lens. Image noise at long exposures and with flash shots was similar to the results we obtained with the EOS 7D. Test shots were almost noise-free up to ISO , after which noise became visible in long exposures. Flash exposures were almost noise-free, although some noise could be seen at ISO 12, and shots taken at this setting were slightly soft, even without noise-reduction processing.

Applying noise-reduction processing softened images slightly and this was visible at ISO settings of and above but less noticeable at lower ISO settings. Edge and corner softening was quite pronounced with the 18mm focal length setting through most of its aperture range. Lateral chromatic aberration was similar to our findings with the EOS 7D — and largely caused by the lens. Coloured fringing was seen in outdoor shots taken with the 18mm focal length.

Barrel distortion was obvious in shots taken with the 18mm focal length but became relatively insignificant at 24mm. Slight pincushioning became visible at 50mm and moderately noticeable at mm. Vignetting edge and corner darkening could be seen in open-aperture shots at all focal length settings except 35mm. We take a look at the Cine, the high-end model in this series.
