Samsung Pro 815 vs Nikon D200 camera reviews
We like more Samsung Pro 815's 3.5" screen than Nikon D200's 2.5" size.
Nikon D200 has 10.2Mpix picture detail and that is better quality than picture at Samsung Pro 815 camera which has 8Mpix.
Optical zoom at Samsung Pro 815 is 15x and for other model you should buy special lenses (what is characteristic of real professional models).
