Yeah did consider the 14-54mm I was all set to buy it new, but came across the Sigma with a Sigma 72mm UV filter for £190 on ebay in as new condition.
When it arrived it was as the seller said there was not a mark on either body, glass or hood and not a single spec of dust inside lens.
Now if this lens wasn't much cop i was going to sell it on and get the 14-54mm,but like i said it been superb it really sharp,i'll show an example at the bottom of this post.
Not to fussed about weather sealing really as i tend to only go out when it sunny anroads, not a fan of the rain.
Ok here a quick snap i took with the Sigma when i first went testing it out.
