Fast Lenses are also known as wide aperture lenses. For starters, know that the lower the number, (f/1.8) the faster the aperture. The higher the number (f/5.6) the slower the aperture. So why do apertures matter? Faster aperture lenses allow more light to hit your camera's sensor and therefore also let your camera shoot at a faster shutter speed. That speed ensures that your photos are blur free in case you may move the camera slightly; that is also called camera shake.
Walk into any major camera retailer and you'll also hear people say, "I want to get a camera where the person will be sharp and I'll get a blurry background." The blurry background effect is affectionately called, "Bokeh." Colloquially, this referred to the quality of the look to the blur, but it means blur in a more mainstream sense these days. If you want the night to fade into a beautiful hazy blur, then fast lenses shot wide open (at f/1.8 or a little bit slower to f/2 or f/2.8) may deliver the look that you want.
Raise Your ISO or Bring a Tripod/Image Stabilized Lens
Don't have a fast lens? You're in luck because many cameras have excellent high ISO results. In English, what this means is just how sensitive your camera's sensor is to light. The general rule is:

Some lenses or cameras have what is called Image Stabilization. It is called different things such as Vibration Compensation, Optical Stabilization, etc. These lenses and cameras will let you shoot handheld at a slower shutter speed. But sometimes even that isn't enough.
This is where you would spring for a tripod and a nice, stable surface. Using a tripod, you can stabilize your camera and shoot at a lower ISO setting with a longer shutter speed. This is how people get motion blur effects of cars moving down city streets or water looking super smooth.
Shoot Wider Angles to Prevent Camera Shake
When taking photos, you should take note of the reciprocal rule of shutter speeds. What this basically means is that your slowest shutter speed should be the reciprocal of your focal length or equivalent view. So that means if you're shooting with a 50mm f1.8 on a Canon 7D, then you'll need to consider the fact that the sensor has a 1.6x crop factor due to the APS-C sensor. That means 50 x 1.6 = 80mm. You should be shooting at 1/80th at a minimum in order to gain steadier photos.
When you shoot with wider angles, that minimum shutter speed goes down. Shooting with a 24mm f1.4 L on a Canon 5D Mk III? Well your minimum shutter speed should be 1/25th. That means you can once again lower your ISO settings to get images with less grain.
Bring the Camera In Closer To Your Body
For even more stabilization when shooting handheld, the best way to shoot is to bring the camera in closer to your body. As a couple of quick reminders:
[click to view image]If you're shooting at night during the winter, chances are that you'll be shivering when you go to take a photo. Here's an analogy to think about for stabilizing your camera: imagine that you're holding a television and about to carry it up a flight of stairs. Which would be easier:
The same concept applies, and so you can surely get better images with your camera in closer to your body.

Don't want your battery life to die? Well, your camera may not be the best to focus in low light. If you keep telling it to try to focus, then refocus, then refocus, then refocus, you'll just end up draining battery life and therefore hating your new camera. Switch the focusing to manual and once you have the subject that you want in focus, fire off the photo. Many modern viewfinders are bright and detailed enough to make this simpler for you.
Keep these tips in mind when you're photographing the night scenes and you'll have even better images to show off on Flickr, 500PX and more.
