How can I consistent achieve tack sharp images, when wanting to focus on eyes in a portrait? I am always using single focus and moving the focus point to the eye and recomposing if necessary. What else would you recommend or what factors can get in the way of a crisp portrait?
This is in the situation of a natural light portrait, no flash, and auto focus settings. I want to achieve a tight shot with the focus precisely on the eyes. Thank you all for your help!
