After purchasing a lense from mpb I read the reviews online here and was quite worried based on the criticisms. To me and my experience, these criticisms seem to be invalid. They delivered my product promptly, it was in the condition they had promised, they had good contact with me throughout the order, and they even required a signature for the delivery so the expensive lense wouldn’t be stolen. I do not see any reason to give them less than 5 stars; the price of the lense they sold me was incredibly competitive as well; barely more than an eBay bid for an unknown quality lense.
