Fixation are excellent. I couried my camera to them for a full service and it was back with me in just under a week. I was recommended them by a few fellow photographers who use them all the time.
. I sent my 100-400 via Jessops and ended up spending £350 to get it fixed. I suspect now that the AF
motor they replaced wasn't even faulty and the lens just needed calibrating. It turned out to be a calibration problem on my camera which was only evident when using the 100-400 at long lengths.
Basicaly from now on, Fixation are likely to get any of my service work.
