What is difference between using a 50 mm lens and using 18-55 at 50 mm?

Is shooting at 50mm using kit lens, e.g., 18-55mm and 50 mm prime lens is same?

  1. Shooting with 50mm lens can let you shoot at aperture as wide as 1.8 but a 18-55mm will allow you to shoot only at 5.0 aperture 
  2. This difference itself is a huge deal. This means you can have the advantage of having faster shutter . Imagine shooting handheld at 1/15s with aperture f5.0 and then at 1/125s with aperture f1.8. This can be significant in low light conditions.
