I have had a few missed focus with my K-5, and it is most probably a
user error on my part. I am looking for some tips from more experienced photographers.
A particular problematic scenario is a person/subject standing in front of a tree, anywhere from 1-10m from me. The face doesn't quite fill the frame or even the red autofocus square. I always use centre spot focus and recompose, but the autofocus mostly locks onto the trees.
This is not immediately obvious on the viewfinder or even the lcd. I tend to find out about the ruined image on my computer screen
. I understand that the trees are a higher contrast subject and that the autofocus sensor covers a larger area than the red spot in the viewfinder.
So what can I do in these kinds of situations?
I can provide a couple of sample shots if the descriptions aren't clear.
The K-5 is my first DSLR, I came from the micro4/3 system. Those cameras have relatively fast contrast-detection and adjustable focus area size. The focus is apparent on the electronic viewfinder/lcd, so I can refocus immediately if it misses. Hence, I am probably spoiled in this area
.
Any tips would be much appreciated.
