Lensrentals: System MTF comparison, Canon vs Nikon

from a less than stellar lens then you shouldn't have to pixel peep to see the lens' flaws, e.g., a lack of corner to corner sharpness.

I was surprised at the measured difference between the Canon combo and the D800 combos.  I wonder if you could really see much difference in 8x10 prints since this is all top notch equipment.

Finally, I fully agree with you that test results are one thing and using the D800 in every day shooting is a different proposition.  Good technique is a must to get the best results from the D800/lens combination you are using.
