because some people do not have good vision, which is why god made focus aids. there is only one miniscule optimum focus point and in most cases a machine will outperform a human, certainly in my case as my vision is just plain awful. the focus aid/autoconfirm on my 5d makes me a 100% better photographer.

Mainly to speed up MF. Can you used the MF zoom, but it take a little (3-5s) longer. For me, when I do bird photography, I could have missed some of the shots.
Yes, good eye sight is a must also. |

The Tago 4/3 AF confirm chips are very good in that they seem more reliable than the older versions. I am gradually replacing all my older chipped adapters with Tago'd ones. But, no chip I have ever used has been 100% reliable in terms of getting the focus right. Sometimes they are spot on, but sometimes obviously a bit off. Thus, it pays to fiddle the focus a bit when using a chip to find the boundaries of when it gives the AF confirm and set an average position. Therefore, they do not speed up manual focusing. But when using my E3 I do rely on them.
In fact, a 4/3 adapter with chip will give AF confirm on my EPL1 when using the Olympus MMF1 4/3 to m4/3 adapter. However, I have never explored this as I prefer to use the VF2 finder for focus setting.
