[QUOTE="Camera Fun, post: 490603, member: 13006"] After fine-tuning my 18-105 over time (first a target/angled ruler and then the dot-tune method), I ended up with an overall setting a -7. However, I noticed some recent general photos weren't quite as sharp as I had hoped and it appeared that I had adjusted the focus too much. So I decided to try the dot-tune again today for more focal lengths (did not change distance to target due to space limitations) and got the following results. 18mm -1.5 24mm -2.5 35mm -5.5 50mm -7.5 70mm -6.5 105mm -7.5 Even though the longer focal focal lengths show a -7 would be appropriate, those were the primary lengths I felt weren't sharp at the focus point. So I'm going to try -5 and -6 settings when I can to see what happens. Has anyone else felt there were any differences between what a focus tuning produced and how their photos turned out? [/QUOTE]
