Hey, I am hoping you can help me sort out a problem I discovered today. I decides to try out my Nikon DX 18-135mm today to take a picture of a bat we found. It's not my favorite lens, but it was what I grabbed and put into my bag. When I mounted the lens onto my D800 I discovered that the autofocus did not work at all. I did check the AF switches on both the lens and the D800 and they were in the proper positions. I swapped the lens with my 50mm and autofocus worked just fine. I've been flipping through my manual and Darrell Young's book trying to figure out why the 18-135mm did not AF. I haven't found much info. Do any of you have any insight? I would be most grateful to figure out if I am doing something wrong.



I tend to clumsily march to the beat of my own off-rhythm drum.

My mom wishes I spent my money on girlie things like dresses, shoes, jewelry, and purses. I'd rather focus on glass.
