My Canon 24-105 lens has been fixed, I'm thrilled with it. I have missed it so much, Calumet fixed it for me. I tested it out at my 9 year old's graduation today, at Hope University! Superb results. Calumet sent it free delivery because I waited a while for it. I would have given 5 stars, but I've been waiting since November for a phone call. I decided to phone them and it was sent the day after! It had been sitting on the "ready shelf". I've used Calumet for years and will continue to do so. I kept forgetting to ring them up, so that's obviously added to the delay. Can't wait to pay them a visit and buy my new studio equipment from them. They will guide me in the right direction!
