hi guys - as some of you may know - I dropped my 400d last weekend and broke sigma f1.4 30mm lens - anyway - this is going to get sent back and hopefully they can sort it out...! well, I've been looking at some other lenses too and I fancy a small zoom (upto about 70mm) and I like sigma... :) there is something like a - Sigma 24-70mm f/2.8 EX DG which seems to retail for a few hundred quid... how much better is it than the lens here - [URL]http://cgi.ebay.co.uk/Sigma-28-70mm-70-300mm-AF-Lens-Set-for-Canon-EOS-EF_W0QQitemZ190234681378QQcmdZViewItem?hash=item190234681378&_trksid=p3286.m14.l1308[/URL] I'm assuming lots...and I'd no doubt have to pay duty etc when it arrives... I already have a canon ultrasonic 70-300mm here - [URL]http://cgi.ebay.co.uk/NEW-CANON-EF-75-300mm-F-4-0-5-6-III-USM-LENS-in-UK_W0QQitemZ170236261746QQihZ007QQcategoryZ30070QQssPageNameZWDVWQQrdZ1QQcmdZViewItem[/URL] is is a suitable 28-300mm that would be comparable..? _ heard there are some by tamron but I'm not sure what they are like... I don't want any compromise as I love my sigma - the colours are lush...but then I can't afford to spend loads either...
