Re: 70-200 f2.8 AF problem

In reply to the last couple of posts (the lens is enroute to the repair facility so there isn't any new troubleshooting I can do):

 

- I didn't use the "Restore to Factory Settings" option, however I went methodically through every AF option in the camera menu and either changed or disabled the function to see if it had an effect.

 

- I was able to manually focus on subjects (even those within the 25 ft range), but I did not test the entire range of the manual focusing ring to see if there was any binding, etc.

 

- I have a standard UV filter on the lens that I never removed.  The UV filter, however, looked clean and undamaged to the naked eye.

 

Thanks to all that are contributing to this discussion.  You are a wealth of knowledge and information.

Thanks for the update. 

 

Well worth the repair, even in KEH's 'bargan' condition the lens sells for 3 times that.
