The Resolution Game 21MP vs. 12MP ?!
Does anyone really expect that a 21.1-megapixel camera would not handily outperform a 12.1-megapixel camera in terms of resolution? Field shooting today in multiple trials leaves no doubt, but there is considerably more to the story than just resolution. Stay tuned for a body-to-body comparison of the Nikon D3 with the Canon EOS 1Ds Mark III (the resolution aspect).
Some will cry “foul!” that comparing the two cameras is wrong because of the mismatched resolution, but it’s just as reasonable as comparing a DX sensor camera to a full-frame camera as I did in D2x vs EOS (still highly instructive even if those cameras aren’t on your shopping list). For anyone considering a full-frame digital camera, The D3 and 1DsM3 are the two contenders, and there are numerous aspects to “performance” beyond resolution. Anyway, one is free to not read anything that disrupts cherished cognitive commitments.
I’ve now made three different A/B field comparisons between the 12.1MP Nikon D3 and 21.1MP Canon EOS 1Ds Mark III. In all three cases, the results seen are highly consistent, with the 1DsM3 showing higher resolving power.
The Canon EOS 1Ds Mark III is the resolution champ. Does anyone really expect that a 21.1-megapixel camera would not handily outperform a 12.1-megapixel camera in terms of resolution? Field shooting today in multiple trials leaves no doubt, but there is considerably more to the story than just resolution.
