Eager as boy with a new toy, I did want to test my new lens, to see how sharp it really is.
But I made a mistake... anyone who can spot it get's a cookie!
Due to the low light condition, I put the aperature wide open, so the field of depth became a bit to small... hence the sharpness isn't always there where I wanted it... I hope at least. I'd go crazy if it turned out to be frontfocus...

Kris, I'll take a stab at this, You left it on auto focus and the camera focused on the bread and left the bird a little out of focus. Let me know if I get a cookie, Mark

You do get a cookie... ;D
I'll need plenty more practice ( and I'm not afraid to admit it) ;)

Kris, The easiest way I found for that is to put the focus dot that is blinking on the subject you want ,hold the shutter button half way down, then move the camera to include what you want in the shot, then take the shot, the focus will not change. I find that is faster than trying to turn off the auto focus and trying to manually focus. Mark

In this case, the camera was on a tripod, so I couldn't swing it fast enough... I tried different metering-modes, but the breadlump seemed far to appealing to the AF.

RoughRider has the correct idea there Kris. The best option is to use your Focus Lock/Exposure Lock function and you should be able to force the focus or exposure or both, on the part of the image you need.......... 8-)

I use that too on my camera, mainly because its manual focus isnt really fast.

Kris,
the right hand button under your thumb when taking shots has a magnifying glass with a + symbol on it. This is the zoom button when reviewing photos, and is used to select AF points when taking pictures.
If you press the AF select button when shooting then all of the AF points in the viewfinder will light up, and by using the scroll wheel behind the shutter button then you can select which of the AF points you want to use instead of all 9 at once. Once the desired spot is highlighted then half press the shutter to set it.
I have mine set on the center spot as a standard. I focus on the point of interest using the center spot, half press the shutter to lock the focus, then reframe and fully press the shutter.
If your point of interest is staying on one place, then you can select a focus point which is closer to it and use this to focus, this requires less reframing between each shot.
e.g. when taking portrait shots of people then you would go for the extreme right focus point, then rotate the camera to a portrait position, placing the focus point directly over the eyes of the subject.
Restricting the focus points also makes the AF faster, as the camera is trying to balance less information, and by going for the centre spot it is ideal for panning aircraft, which generally fill the centre of the frame.

Well Steve, that's one heck of a tip! I was struggling a bit with the af-points. I'm going to check this out. Funny that I don't seem to recall reading that in the manual.

I also put it on a small spot, although my cam isnt that advanced on the focusing part. It still works good, you can easily pick a certain spot on objects.

this has been helpful, i just realized i have a nine box AF and if i depress the button halfway the camera picks the brightest object near the center and focuses on it (So i can change the focus) i only have an Kodak C713
