Shooting wide open (f/1.8, for example)

19Fast prime lenses such as a 50mm f/1.8 are an excellent choice for low-light shooting because you can shoot with the aperture wide open to let more light in, which helps to keep ISO lower. Generally, these fast primes don’t have image stabilisation – this is more common with zoom lenses – although Tamron produces a number of fast primes that have this feature, resulting in the best of both worlds.
