Wfrank, I would be interesting in seeing test it at 3-5M distance use a 3D object. Do the test as quick as you can. Don't give yourself too much time focusing when you use your eyes. And try to use focus confirmation once you know how much you should further turning the ring once bip start sound. And then tell us your results.
It really depend what you shoot, for really accurate focus, depend on distance, lighting, and contrast of focus point, human need a feedback system to lock the focus ie. slow, slower or even turning back and forth to detect critical focus. that also apply with slow down the lens and focus, because critical focus is harder to decide now.
Sebboh. Use WO focus significantly reduce people focusing decision time and the real DOF will cover the slightly focus error due to either your eye or focus confirmation.
Wfrank, The test you did exactly the case you want focus by eyes. That is when I use my Zeiss 35mm take portrait since most of the case my subject is within 1M.
I agree anything keep you away from subject frame is distracting, that is why I prefer matt to split screen. But sometimes, there is always compromise has to do to get the shot. I always use center point to do focus confirmation, and recompose no longer a problem with longer distance or slow down the lens, which are the two case I use mostly for focus confirmation in need of speed.
Once you are more familiar with focus confirmation, you don't need pay more attention than you should to the extend to distract you, at least not by much.
As I said, 25% of case I use FoCo, and 35% I use it get me quickly there then use my eyes. I will not discard any of them and will use it whenever it need to get job done quickly.
All I am talking about is when shooting time is limited. Otherwise, either LV, focus by eye, by confirmation, all will just work fine.
A side question for Canon user, will the bip become solid once in focus?
