I'm very surprised by these comments, My experiences have been this is the worst store on the planet. Prices are unbelievably high (the last lens I priced at TCS was $1300 higher). Tried to purchase an adaptor ring to mount a macro ring flash on my macro lens, was informed the only thing that goes on the front of a macro lens is a filter or lens cap there is no such thing as flash mount adapter. Went to buy a drop in polarizer was told there is no such thing as a filter that screws on to the front of 500 and 600 mm lenses, the employee clearly had no idea what a drop in filter is.
