I have been thinking... sigma 17-70mm OS, Tamron 17-50mm vc version and canon 17-55mm
For sigma one, dont have fix f stop...and tamron have shorter focal range (less 5mm), all three have anti shake function and in term of price sigma 17-70mm OS is cheaper about S$700++
Basically, but for IQ ... i am not sure...so need recommendation...
