How do you get such a clean shot.
I find that my hand just shake too much and the photo ends up noise as hell. even at ISO100 and a quick shutter speed.
Its even worse in low light as i have the shutter open for longer
1 - You need a tripod. Failing that, you need more light.
2 - ISO increasing will create noise, as will longer exposures but usually to a lesser extent. Dark colours show more noise than light colours, so if you're underexposing a shot in an attempt to keep the shutter speed quick, there will be noise. Refer to #1.
3 - General rule of thumb for handholding is that your focal length is equal to the longest shutter speed you can handhold at. For example, handholding a 200mm lens, you could expect to handhold a sharp shot at 1/200sec. Of course, some people can do it better than others, so it's up to the individual. As such, you can handhold a wider lens with a much longer shutter speed than you could with a long lens.
