Pretty much right on the 30,000 actuations mark my mamiya afd (mark 1) shutter broke, so as usual I contacted MAC group in Westchester, sent the body in and it was repaired immediately, and sent back to me, the whole thing took about 7 days from posting it to getting it back repaired. I also got them to check a couple of lenses and another body for me which they did for free. The person there you speak to on the phone is professional, and nice. Last time this happened I needed the camera straight away so they sent me a loaner, no questions asked, no deposits or anything, the only condition was that I sent it back to them when I'd done with it. Compare that to when my 1ds mark 2 needed a 3rd replacement for the wobbly firewire port and the difference is massive. It really shouldn't be overlooked, when your camera goes down, being able to send it somewhere that can sort it immediately is so valuable. Thank you Mamiya/MAC group.
