Ok guys and girls who have the 24-105 f4 L IS what is your sharpest f stop for this lens? I have been using this lens for about 3 weeks and to be honest I am not the happyest. Some pics are looking ok but others are not so good. I am no noob to photography so user error is not likly but hey still a possibility lol
If anyone has any pictures or suggestions please let me know. Ill post some pictures soon.
