Are primes brighter and sharper than wide open zooms
Hi,
Given two lenses, one a prime (say 28mm) and the other a zoom (say 28-75mm) and both with an aperture of f2.8 - - Will the prime be brighter than the zoom because it has fewer lens elements? - Will the prime be sharper wide open than the zoom at 28mm? Ofcourse, a lot will depend on the particular makes and models being compared but is there a rule of thumb? - Siddhartha |
