Amazing, friendly and personable staff, in particular Jay from the Euston store in London made it a great customer experience. Very knowledgable and even when he wasn't on certain makes he would ensure to give me the most accurate information and advice possible. I am very happy with my first dslr camera that I have bought and purchased a prime lense with this. I am very pleased with Calumet's specifications for used camera and accessories and the way everything is in such pristine condition means I will certainly be purchasing soon and ensuring to let my friends know this is a professional place to come to!
