PReview posted its very comprehensive review of the Canon EOS 50D digital SLR camera. Announced exactly after a year since the introduction of the 40d, the 50D has better specs in many aspects except the 0.2 fps slower continuous shooting speed. The question for many current Canon 40D user is, is this a worthy upgrade?

Perhaps not.

In the studio scene comparison with both JPEG and RAW shooting modes, the tests have shown the 50D with 15 megapixel sensor does not offer any advantages compared to 10 or 12 megapixel cameras. There are plenty of such examples there. For example,

When compared to Nikon D300 in studio scene comparison,

…The EOS 50D has a three megapixel advantage over the D300 but again this does not translate into a larger amount of detail. In fact the D300 actually manages eke out a little more detail in some areas of the image…

When compared to Canon 40D,

… both cameras images look crisper and exhibit better detail but the 40D stills beats the newer model in terms of per pixel detail. Despite of a 22% increase in vertical and horizontal resolution the extra detail captured by the 50D is marginal…

By cramping 15 megapixel into the APS-C sized sensor, the 50D actually showed worse high ISO performance and dynamic range than the 10 megapixel 40D.  In the unenthusiastic final conclusion, the reviewer stated that “It appears that Canon has reached the limit of what is sensible, in terms of megapixels on an APS-C sensor.”

Don’t get me wrong though. The Canon EOS 50D is still a solid camera that has many other improvements over its predecessor, excellent feature sets compared to its competitors. Perhaps it did not offer a strong reason for Canon 40D users to upgrade if image quality is the only thing important, many will still find the 50D attractive as one of the few top models in the cropped sensor DSLR markets.
