    So I just got my Nikkor 50mm 1.4 and I had it out today shooting some pics. As soon as I got my photos into LR3 I noticed that each photo when zoomed in seemed to be extremely grainy. Normally I get really clean crisp focus out of my kit lens. I have no idea what I'm doing wrong or why this is happening. Anyone got any ideas?

    Can you post some examples? Full images, and 100% crops of the 'grainy' areas, as well as what you consider to be acceptable with another lens?

    Remember that when you're shooting wide open with your 1.4, DoF, especially at shorter camera-to-subject distances can be VERY shallow, sometimes in the order of an inch or two. Is it possible you were shooting wide open and slightly missed focus?

    Graininess shouldn't be from a lens, it's probably because the camera hiked the ISO on you.

    Digital noise won't be directly influenced by the lens, but can be influenced by the exposure.

    Grain is a term the relates to film and the size of the light sensitive particles in the emulsion.

    If you are shooting JPEG and pixel peeping, you could be seeing the 8x8 pixel squares that JPEG converts an image into. As JPEG quality is reduced those squares become much more noticeable.

    Good detectives we have here! The ISO is a prime suspect...police are expected to arrest the ISO any day now and charge it with excessive graininess inducement, contributing to the ruination of photographs, and disorderly conduct.,and inciting Noise Reduction,and possibly a couple other charges.

    Those photos are not what I would classify as "extremely grainy". I would substitute the word slightly for extremely.

    I don't really see what you're complaining about... They look fine to me.

    How far are you zooming in when they look 'grainy'?
