I've just bought a Pentax K-x as my first dSLR camera (came with a 18-55mm lens) and I'm stuck on how to capture fast-moving shots at night time. An example of a picture I'm trying to achieve is below:
Obviously I wouldn't able to take pictures this close up due to the zoom of my lens (this isn't the issue). From what I can gather though, the shutter speed needs to be extremely fast (like 1/1200). However, the low light would make my pictures nearly pitch black. Would I need to buy another lens with a larger aperture (eg. 50mm f/1.4) to achieve results similar to the pic above?
