As some of you know, we use the shiz out of our 75-300 lens. High usage coupled with our outdoor lifestyle has introduced to our lens what no one wants...dirt inside.
Do any of you open up your lenses for cleaning? Or does everyone drop them off at the local Canon dealer and avoid the hassle.
Any advice on this matter would be great. We're about to head out for vacation in three weeks and want this lens ready. Just trying to figure out the best way to get it cleaned up.
Thanks!
