<p>i had a 300/2.8 autofocus fail, not significantly different from your problem. it was $195, the shipping was almost $100 both ways, tho... i think you will only be in a couple hundred bucks if the parts are available. let us know when it is fixed. another good repair company that i have used for out of service parts is Midwest camera repair. they actually specialize in older AF lenses.</p>

<p>all the comments of 8-10k for repairs is complete nonsense. Canon has flat rate repair prices for almost all of their L lenses. <br />it should be around $400-500, If they still carry the parts. if it is an older 600, then you will probably have to find a repair center other than canon. KEH https://www.keh.com/page/repair-pricing has a flat rate of $195 for any repair to a canon lens greater than 200mm. just call around. if you are going to repair through canon sign up for CPS first. (canon professional services) you will get better service and a discount on repair...</p>
