Originally posted by Rude Personally, I'd look at the Tamron 17-50. Seems to have great reviews, is well priced and can be purchased new so there's some quality assurance (at least you can return). Hope that helps.
Thanks but I didn't say I wanted that range... I am talking about a wedding and if anything the Tamron 28-75 I have is too short (one of the first replies said that, and I agree) - I'd really like a sort of 45-100 f2.8 but I don't have one and I am not going to buy one (the DA 50-135) for now.
For the wider range, I have the DA16-45mm so I don't need a 17-50, ok yeah a stop faster but I'm not going to be using f2.8 at anything wider than 40mm.
Well thanks guys - I'll do a few tests myself and if I find (like I think I will) that the Sigma is not worth the size or the loss of 5mm at the long end, expect to see it sale on here!
