OK. As this is my 2nd post (first was in the intro section), cut me some slack if it is really stupid. I just got a D90 w/ kit 18-105/f3.5. In Aperture mode, in some instances I can not set get it to go all the way to f3.5 on the 18-105. It will let me get close to 3.5 (like 3.8). After fiddling around it, holding shutter half way, turning off and on, or spinning to P or S then back to A, it will eventually let me go to the f3.5. Am I missing something or is my camera not working correctly. Sometimes, it goes to f3.5 no problem. Great forum and I glad I found it. Beware, you will have some pics coming for some C&C.
