I'm trying to buy a wide zoom lens, one of tokina at-x235af pro 20-35 f2.8, sigma af 2.8 20-40mm ex dg and pentax fa 20-35 f4 al.
the prices of new lenses are too high. so i tried to get a used one. i got to know it takes years. is there anybody who can give brief reviews about those lenses. thank you 인터넷을 열면 낯 뜨거운 사이트가 나타나세요? PC지기로 검사해 보세요. http://messenger.freechal.com/FcVaccine/FcVacMain.asp
