    Hi
    can somebody tell me the difference between compact and SLR cameras comparing the noise at low light, no flash. Lets say that both have Zeiss optics.
    1. Does it make a big difference between them if I use, say, ISO400, 1/20 on both?
    2. Is the previous setup better or ISO50 1/4

    Thanks

    the DSLR will have less noise. it has a bigger sensor.

    Bigger sensor = Bigger pixels = Less noise.

    ISO 400 on a compact is going to look kind of bad compared to the same on a dSLR. Most dSLRs perform well up to ISO 400.

    If you can use a tripod, use the lowest ISO you can, set the aperture to the size you want, and expose for however long it takes.

    Also let's not say both have Zeiss optics, because it doesn't necessarily mean anything, except perhaps that Zeiss are willing to have their name put on the product.

    And how important is if it has CMOS or CCD sensor? Again for the noise?

    The sensor on those two cameras are basically the same. However, there are other things that determine noise levels. The electronics and firmware of the camera also affect the noise in an image.

    Even though those two sensors are practically identical, I believe that the 20D shows less noise.

    Really though...the 350D is still miles ahead of the smaller sensor cameras.
