Dans les conclusions : Nikon D300S Review: 30. Conclusion: Digital Photography Review

"If you look closely, it's not uncommon to notice 'grain' in what should be clear blue skies and this isn't the camera for you if that worries you (it's rarely objectionable, particularly at normal viewing distances, but it is there)."

Effectivement, le D300s a surement aussi ses défauts, dû à un traitement du signal plus poussé probablement.
Canon reste le maitre en fabrication de capteurs.
