a noob question.
does the quality of a lens contribute to the noise level of a picture?
because i notice the dark portions/shadow areas of the pics from my D90 are quite grainy than they should..even at ISOs sometimes as low as 400.
according to reviews, noise handling of D90 is excellent. i did not expect seeing such amount noise at ISO400
i'm using Tamron 18-270 & 50mm f/1.8 lens.
thanks for kind inputs
