they should make a jurong goat park.
sigma 10-20, if you get grey, can get for cheaper price. i cannot remember how much i got mine for pentax mount for, but i think it was $600+ , not a bad price at all!
for that one, you can try lord's.. the last i asked for a quote (quite some time ago) for a friend, theirs was very competitive, grey though
grey 10-20 should be around the 680 region for f-mount.
i wonder if it is the same as eikin's one..
thanks for the heads up. i'll check out with lord's when i finally decide to buy. now still must concentrate on my backpack! haha. still havent got the time to go down and try out the bags =.=
