i'm quoted S$750(with GST) for sigma 70-200 f2.8 HSM II brand new local warranty(according to the uncle) at funan 2nd floor shop, joy's but when i ask for the item the uncle refuse to show it to me with lame excuse saying "it's at my other shop at different floor, if u confirm u wanna purchase i will get it for you in 5 minutes" then i ask why don't u get it for me first so i can see and then he told me even more ridiculous reply "u must confirm that u want to get the lens then i'll get it for you, cos if i fetch it up, another customer might come when i leave", so i just left, i dun think i can trust that shop to buy anything, but if u're willing to take the risk it's really really a bargain from other shops that selling the sigma 70-200 f2.8 HSM II for around S$1300, also i manage to compare sigma 70-200 f2.8 HSM II and Canon 70-200 f2.8 L non-IS at john 3:16, i feel the build quality both is very well made but i notice the sigma 70-200 f2.8 HSM II is a bit soft wide open, maybe the copy i'm trying, i dun know, just my experience last week
