Outdoor scene - Sony Alpha DSLR-A100 versus Canon EOS-350D using kit
lenses
To compare real-life performance we shot the
same scene with the Sony Alpha DSLR-A100 and Canon EOS-350D within
a few moments of each other using their best quality JPEG settings. The
Sony was fitted with the DT 18-70mm while the Canon was fitted with the
18-55mm EF-S, both set to an aperture of f8 in Aperture Priority mode. The
crops are taken from far left, center and far right portions of the originals
and presented here at 100%.
The image left was taken with the Sony Alpha DSLR-A100 using the DT 18-70mm
lens at 26mm f8 (39mm equivalent); the original JPEG measured 3.70MB.
Viewed at 100%, the crops show roughly equivalent amounts of actual detail.
This isn't entirely surprising since the difference between 8 and 10 Megapixels
is not actually as great as it sounds in real life. Probably the greatest
visible difference in this test is from the crops of the mountains from
the far left side of each image. Coloured fringing is apparent on both samples,
although the Sony sample is visibly softer.
It's also interesting to note that when using their default colour and Auto
white balance settings in this environment, the Sony A100 delivered a much
cooler image than the Canon 350D, which relatively speaking looked quite
warm.
