For me personally, the shutter speed is the best invention for cameras as it freezes the action and reduces the effects of the camera shake. If I shoot a static subject matter, then I will try a shot with a shutter speed of 1/400. This, however, creates a less than perfect photo. Because of this, I recommend using a higher shutter speed. If it was a flying bird I was photographing, the minimum of 1/1500 would be ideal but personally, I would prefer to use a shutter speed of 1/2000+.
