[QUOTE="Adrian MacNair, post: 137954, member: 13773"] Thanks, jwstl. yes, I noticed you can't autofocus since you need a focus motor like on a D300. But there's a decent hack to it. The 13 focal points on the viewfinder still measure distance, so while I'm manually focussing with the lens the focal point if I hold the shutter halfway down then the circle will go solid green when I'm sharp.
