Although I've been generally impressed with my 24-105 purchased last December, it has disappointed me a tad when viewed at 100%. Not that this really matters because rarely do I print at that crop size. Anyway, to cut the story short, I decided to take it into Canon's North Ryde facility and it calibrated or whatever.
The results are very good. It definitely seems sharper, and the turnaround time was 2 days.
Congrat's to Canon for excellent service.
