My lens was getting replaced. I had to constantly make phone calls to see what was happening. I was told repeatedly by reza and one other that they would call back and never did. Eventually I got a hire one to use but was totally different size and different thread so none of my filters fitted. One main issue was that this lens broke for the second time whilst I was on a workshop in the Faroe Islands. This cost a lot of money and I was left with no way of taking photos. I have no faith in calumet and no faith in Fuji products. Happy to speak and discuss and I will be putting in a full complaint to the chairman of calumet and to Fuji uk. Alex
