[QUOTE="gustafson, post: 562840, member: 40735"] I'm pretty sure I was using the center focus point, as I generally keep it locked there. I did use the green dot, but these were handheld (sitting on couch, but upper body not braced against anything) and I'm not 100% sure if the green dot was still there the instant the shutter was pressed. At f/2.5, the DOF is so thin that even a slight sway back or forth can botch the focusing, and I believe that is what was happening. One of my takeaways is to brace the upper body against a wall or other vertical object when shooting with narrow DOFs to minimize this possibility. Sent from my iPhone using Tapatalk [/QUOTE]
