    It's also about cachet. A lens with constant aperture is considered to me a more professional lens than one with varying aperture (especially if it's constant af f2.8 or above).

    I'd say it is a bit more than that, the constant aperture lenses are better quality. Although you can get a Canon pro L lens that has variable aperture across the zoom range, I don't think you can get the better grade glass from Sigma or Tamron without buying the constant aperture zooms or primes.
