Focusing Follies, article by Ctein. Like usual from Ctein, a well written technical article, this time about the seldom-talked-about weaknesses of all traditional camera focusing methods, and what might be done about it.
What's that whole story about making focus in tune? I didn't really get it. Just notice that many of my pictures are out of focus with that automatic focus system. Is there a way to improve that?
Funny enough I've never myself noticed all those accuracies that Ctein talks about.
That's why I noticed and published one more John image, I was checking focus in them, they were taken with a super-critical fast lens. All sharp.
I recommend that you only use the middle focus point, point that where you want to focus, and then re-compose the picture. This is more accurate than letting the camera select the focus point.
