i have the 24-105 I have compared both lens, mas sharp ang 24-105 compared sa 24-70 specially at f/4, advantage sa 24-70 is the 2.8 which is good, i prefer the 24-105 because im a strobist shooter, strobist set up starts f/4 onwards
, i have primes for ambient lighting naman
agree get the 135 f2 L hands down ko ani na lens
