What can I say, to get the most competitive price for such a good product, I tell Best. I bought two of them once for my fixed focal length in 35mm from Sigma and the travel tele 18-200mm and I'm very excited. One can without any problem the lens hood top screw, or the lid. In my 70mm I have one from another company "Photo something" that is compared to the still expensive but not of this quality. I'll buy it now also for my telephoto zoom sigma 50-500, I hope that fits as well as perfect plan.
