I hope that you can get it repaired at not too much cost, but it may be worth looking at getting something else just in case it goes wrong again, but the problem I see, is that the lens has the focus motor inside and that may limit you This will be third such repair on the same lens, lasted about 5years this time, not too bad I guess.Original failure as i mentioned above, occurred when I fell off a step ladder at Mildenhall onto it! Re the motor in the lens, that is normal in Canon and Nikon, I see you have Sony/Minolta which uses motor in the body. Makes lenses cheaper as the motor/Vibration reuction is in the body and works on all lenses, unfortunately VR came out after I changed from Minlota to canon 10years ago! However if that motr fails you lose all your af in one hit, and need a spare body, if a Canon/Nikon lens motor fails, you can use another lens! Swings or roundabouts I guess Like the sound of a "normal zooming" 100-400 though, never too struck on push/pull, not too precise on moving subjects, and about time Canon did update this lens, it's been about for years! I think I'll start saving for that, so when this repair fails again, I will bin it then
