Če lahko skopiram tekst s tujega foto foruma:
They're both about the same in terms of sharpness.
The zoom can go to 200mm, where the 135L cannot.
The 135L can go to f/2.0, where the zoom cannot.
The 135L is 1/2 the cost and weight of the zoom.
The zoom has IS, the 135L does not.
F2.8 to F2 is a whole stop faster
Take your pick as to what you value and go accordingly.
AF bi "naj" imel malenkost hitrejši 70-200mk2. Če "rabiš" zmanjšanje ISO-ta, se F2.0 pozna za celo stopnjo, bo pa verjetno malo uporabnikov obeh objektivov na tem forumu da bi povedali kaj več iz prve roke...
