Alex Burack & Patrick Singleton have recently posted their head-to-head review of the Nikon D200 and Canon EOS 5D and wrote;
“The D200 is a much faster camera with a more logical ergonomic design. With the Nikon, users can turn the camera on and snap off a shot in a single motion – an action that would require two hands and far more time with the 5D. The D200 can also shoot 5 frames a second, while the 5D can only muster 3. This combined with the D200’s more robust body (not to mention its more affordable price tag), makes it a much more formidable alternative for photojournalists or casual shooters.
At lower sensitivity settings (ISO 100-400), the two cameras produce images of comparable quality in terms of noise, color, dynamic range and sharpness. While the 5D still retains a slight edge, the difference is negligible for the quality both cameras produce. However, once the sensitivity is pushed to ISO 400 and beyond, Canon earns the extra $1,300 tacked on the 5D’s price tag. At sensitivity settings beyond ISO 500, the 5D continues to create images of exception quality, while the D200 falters and produces results more consistent with consumer-level designs.”
