What is the question?

There is not much anyone can tell you. It could've been a missed focus, for all we know you might have had all focusing points on and the camera decided to pick something else. And what camera are you using?

Post the images at actual size instead of pixel peep size .
That way we can see the whole image and this might give us more of a clue.
The pics are too tight to be useful.
Also keep the EXIF data intact or at least post it. That might give a few clues as well.

As phreeky said, what is your question?

The top one just looks like you missed the focus rather than it being soft.

hm,

I believe he is asking why photos shot close-up are crisp, and ones far away look softer. This is normal I think, there is haze, and allot of crap in the air, so details of faraway subjects will be less crisp.

or maybe I'm wrong and he is asking, about range, shooting wide yields good results, and on telephoto end things aren't as crisp...

That wont occur at that kind of distance though.

you are telling me, tree shot at 1m will have same amount of detail as a tree shot from 100m and cropped out?

when light passes through air, it interacts with **** that floats around, and is being scattered, so distance shots will loose detail, will look less crisp compared to photos shot at shorter distances.

correct me if I'm wrong

We don't know at what distance he was from the subject.
The crop is too tight to tell anything.
Admittedly, heat haze did occur to me as well, but it's too hard to tell.
We need to see what else is in the frame.

Until we see the full photo everyone is just really taking stabs in the dark.

That's a 105mm lens there (shot @ 93mm apparently), so the shot can't be from all that far away! Believe me I know what heat haze and stuff is like, that isn't it.

I tend to agree - but the thought did cross my mind.

you are forgetting this isn't a full head shot at 93mm, we yet have to see the full picture. First image is a 100% crop from a bigger frame, that means it's a very small area of the huge 5DMKII file!

Subject must have been far away, to make head-shot crop look like this at 100%, do you understand my logic?

but, I don't know how haze looks, I've just seen it on landscape shots... so if you have experience, you must be right... but we have to see the full 100% image to confirm any hypothesis.

Are you using center point focus? The first shot looks like focus was way off, and depth of field should be fine at f8. Your lens if sharp in the second shot.

ok i am sorry for not posting everything i am new to this form i am using a xsi

In the second pic it look like you focussed on the trees in the back,
