    Default grainy pics

    hi,
    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

    Expose it properly. Underexposed pictures will suffer from noise.

    Most DSLRs can see Noise at ISO 400 but esp in dark areas, its normal. Even using FF but at its minimum.

    Lens dun really contribute to noise, even if there is, its so tiny minor. But cheap lens are softer whereas expensive ones are sharper. Ultimately for ultimate sharpness, PP is a end choice but will slightly increase noise as well.

    thanks for all the notes
    i was choosing some pics to post here and i had to reduce the size.
    when i compressed them a little and they became quite smooth-looking.
    the compressed files cannot enlarge as original ones when viewed at 100% so the noise became not as obvious as before

    I just came across the following topic. Perhaps it may help in this issue. Please ignore the title which sounds like totally no relevant to this thread. Simply read through the article.
