I'm tempted to buy the Sigma 10-20mm from them, seeing as no-one else in the UK has them. The only issue is with Sigma really. I know they have quality control issues so I'm wondering what to do if I get a dud lens. Anyone have any info? Obviously the 7 day UK return thing won't work there. I'm still waiting to hear back from them myself. I emailed them last night. Anyone?
