thanks for the suggestions, tamron 17-50 is around $300-350 here im not sure about the 17-40
1st thing to consider is the anti-shake feature, i honestly need it.. the 17-85 is the at the same price
range as tamron 17-50, therefore i need to choose between IQ or IS+range...
can i have all those features in just $300 range? kekeke!
