Don't forget:

  • Brighter Viewfinder
  • More accurate auto focus

If you are using a camera with a padf system, why would an F 1.4 lens provide more accuracy then an F 4 lens or F 2.8 ??

  • They tend to be sharper (a high quality f/2.8 lens is likely sharper at f/3.5 or f/5.6 then a lens with a maximum aperture of f/3.5).
  • The wider apertures tend to be bundled with other features (i.e better build quality, weatherproofing, better optical quality).
