It does take some getting used to, for sure. It's very much worth the effort though, I think.
I realise you were pretty close in the second one, but even so it doesn't look all that sharp. With an exposure of 1/1250, it's obviously not camera shake!
Sometimes I found with this lens on the K10D, the AF would think that it was already in focus, even if it wasn't. It's a good plan to force it to refocus by focusing on something very close (or very far in this case) first, and then refocusing on your subject.

Here we have two decent 'practice shots', a little oversaturated but otherwise OK. The subject matter and shooting angles don't really do it for me but shots like this help you get used to a lens.
I do agree that the lens sometimes does take a little coaxing to focus on distant objects though.

I presume the selective focus on the end of the log was deliberate though Chris? It's a good plan to force it to refocus by focusing on something very close (or very far in this case) first, and then refocusing on your subject.

I'm sure it was... but at F8, I'd have expected it to be sharper, and see more DOF I guess.I presume the selective focus on the end of the log was deliberate though Chris?
Of course, the 'focus and reframe' method of selecting focus point will be at its very worst at 10mm up close like this.

i think this is going to take some getting used to.
