Popped into currys as they have Canon 50mm f1.8 for £76 at the moment. The only two lenses they had were one on display or one with security seal broken which i can only assume has been opened and put back in for whatever reason. I have inspected it as best I can and got them to document on receipt but have i been foolish to buy it unsealed? I have checked and I can return it if need be.
