Guys, I need some feedback about the zoom lenses, 24-90/3.5-4.5 and 20-35/4. Both are similarly priced, so I just want to know which one offers more sharpness/USD :)
I have used 28-70/4 (thinking to buy a new one), and still use 70-200/4-5.6. both can't really equal prime lenses, but I usually stop down at least 2 stops, and the sharpness is excellent. Thanks! Winston
