Originally posted by WerTicus total non issue, you can clearly see what is and isn't in focus. Its like missing training wheels when you know how to ride.
I have the Kx and K100D (which has those red-flash AF selection points).
I mostly do not miss them.
But then again I use only the central focusing point -
and on the K100D, despite knowing the green hex is the focus confirmation -
I am sometimes still fooled into thinking the (center) red-flash AF selection point is a focus confirmation - I have to conscientiously look down for the green hex confirmation.
All this may sound like I think the red-flash AF selection points are a distraction....
BUT not quite, there are times in lower light levels it is hard to see the AF markings/brackets in the viewfinder -
so I had to develop my trick of estimating the intersection of imaginary diagonals from corner to corner to "guess" the central position -
this may seem pedantic - but even in low light I need to know where my AF point is.
This is when those red-flash AF selection points would be a boon, even if it is only for the central position for my case.
Ideally it would be great to have an option to switch those on or off -
and for my shooting it probably would be mostly On -
but I can see for anyone who shoots mainly in daylight -
those red-flash AF selection points could actually be a distraction.
