This is my first post, but I have been a reader for quite awhile. I purchased a 70-300L lens to replace my 70-200 f4. I have a question about what I feel is an unusual amount of play in the focusing ring. I am not talking about backlash, but what appears to be more than usual side play or looseness on the ring itself. When comparing this to my other lenses it seem excessive, especially my 70-200. This is my second copy (I returned the first lens). The first copy was the same. Has anyone that owns this lens noticed this. Other than that the lens exceeds my expectations. Sharpness is on par or better than my 70-200. If this a bad run of this lens I don't want to get stuck with a bad copy. Thanks in advance for any info regarding this.
