It’s no secret that the Canon EF 70-200mm f/2.8 L IS is my favourite lens for unobtrusive candid moments—the lens and full frame body combo makes so much sense. The cost of buying one can be prohibitive not to mention its weight alone somewhat discouraging. Beyond its first impressions comes a lifetime of beautiful moments captured on this highly popular L lens. I think I’ve had this workhorse lens for nearly as long as I’ve been shooting professionally and it has traveled to just as many overseas destination. As a result the front end (indicated by the red arrows) of the lens has worked itself loose and rattles quite a bit.
Using a plastic ruler, lift up the rubber Manual Focus ring and gently slide it backwards enough to reveal 6 Philips screws (three on top and three below). You want to tighten the 3 top ones.
The screws may not be immediately visible until you rotate the focusing ring to line up the holes with the screws. Using a Philips 000x40m screw driver (the same size used in my Speedlite 580EX II Hotshoe Fix) Tighten the screws using as much torque as much as necessary.
