|Canon EOS-5D Mk III with EF 24-70mm f/2.8L II, EF 35mm f/2 IS and Sigma 35mm f/1.4 DG|
Most of my readers probably know by now, I have picked the Canon EOS-5D Mk III as the best value in full frame DSLR camera on the market today. Also I am not a big fan of the megapixel race, especially with Nikon and Sony introducing cameras with more and more pixels packed into their sensors. It can be an eye-catching number on a marketing brochure but I find a high quality sensor of 18 to 22 MP more than enough for almost all of my work.
DxOMark did an analysis of the Canon EOS-5D Mk III vs. Nikon D800 with various lenses. The Nikon D800 has a 36 MP sensor versus 22 MP for the 5D Mk III, but the tests reveal the Canon camera is capable of similar sharpness and of achieving a close DxOMark camera/lens score when compared to the Nikon body.
'Given the somewhat lowly-looking pixel count of the Canon EOS 5D Mark III the potential sharpness is, surprisingly, one feature where the camera exceeds expectations. Providing the camera is matched to specific lens models, sharpness can even exceed the Nikon D800 under certain circumstances (when that camera is used with lesser capable lenses). This is great news if you’re looking to invest in one or own one already. If you’re a Canon user and are looking to upgrade, or maybe even switch because of the sensor’s perceived lowly capabilities then this should put your mind at rest. Please look out for next part of this review, where we’ll look at the finer points of the results for camera and lens combinations to choose from and those lenses that you may want to avoid.'
'While the Nikon D800 is capable of getting the best from any lens that’s fitted, it is essential to select lenses specifically to maximise the potential resolution of the sensor. If you’re trading in a Nikon D3X, for example, you may want to confirm that your existing lenses are capable of meeting (or maybe even exceeding) your expectations.'
'While that same principle of choosing the best glass also applies to the Canon, it’s not quite as crucial. In financial terms alone, this may be an important consideration if you have already invested in a sizeable range of lenses. Lenses on the Canon EOS 5D Mark III are without doubt very efficient.'
