To compare real-life performance I shot the same scene with the Canon EOS T3 / 1100D and EOS T3i / 600D within a few moments of each other using their best-quality JPEG settings and base sensitivities.

Both cameras were fitted with their respective kit lenses: the EF-S 18-55mm III and EF-S 18-55mm IS II, both set to f5.6, adjusted to deliver the same vertical field of view, and focused using Live View at the highest magnification.

The image opposite was taken with the Canon EOS T3 / 1100D at 100 ISO with an exposure of 1/640 and the lens set to 21mm f5.6; the original Large Fine JPEG measured 5.22MB. The crops below are taken from the areas marked with the red squares and presented here at 100%.

On this second results page I've compared the EOS T3 / 1100D against the next model up in Canon's DSLR range, the EOS T3i / 600D. There's a bigger difference in total Megapixels here than on the previous page: the T3 / 1100D has 12 Megapixels, compared to 18 on the T3i / 600D, giving the latter 50% more pixels in total. Of course this is the total number of pixels on the sensor, and in linear terms, you're actually only looking at around 20% more pixels horizontally and vertically on the frame - so what does that give you in practice?

Looking at the crops below, both cameras share a family resemblance in image processing style, delivering punchier and more contrasty output by default than Nikon, and both also suffer from coloured fringing, which thanks to the higher resolution of the T3i / 600D, now looks larger and more obvious when viewed at 1:1 on-screen. Once again you'll need to shoot in RAW to easily remove fringing later with software, like the supplied Digital Photo Professional program.

In terms of real-life detail, there's definitely finer details on the T3i / 600D's crops if you look closely. Tiny windows on houses, branches on trees and parked cars all contain more detail in the crops below if you peer closely enough.

But you may have to peer more closely than you thought to spot these differences, which could come as a surprise considering the 50% greater Megapixel count. The T3i / 600D is definitely resolving greater detail, but you'll need to do a double-take to really see it.

Now let's see what benefit shooting in RAW can have in my T3 / 1100D RAW vs JPEG quality page.
