I have a 70-200mm f/2.8G lens (that's probably about 6-7 years old) that I got really cheap as part of a bundle of lenses from someone I know. He told me that he thinks the AF motor on the 70-200 was dying (and this is evidenced by a squeak when focusing--focusing is still spot on and accurate, and quite, but it squeaks when it has to search).
Like I said, it still focuses fine, and is quick, but just makes noises... This must be a first gen lens (he got it used and paid a good amount for it) so there is no papers on the lens, but I did find a place near me that will fix it regardless when the motor does decide to go out.
So anyway, my question is: since we are pretty sure the AF motor is dying, is there any danger in letting it completely die until replacing it? I don't have to worry about it damaging any other components do I?
I can deal with the squeaking noise, but who knows, it may still work for another year or so, or die tomorrow.... either way, I know it's going to crap out at some point, probably sooner than later, but just want to make sure that letting it die is not going to harm anything else. VR motor is still in good shape.
