It looks pretty good I suppose considering you are shooting the lens wide open. What were the results of the focus tests.

Welcome,

If the second picture is a 100% crop then I would have said it looks OK.

I have to say that it looks pretty good to me


I don't know what good composition is.... Sometimes for me composition has to do with a certain brightness or a certain coming to restness and other times it has to do with funny mistakes. There's a kind of rightness and wrongness and sometimes I like rightness and sometimes I like wrongness. Diane Arbus

There is nothing wrong with that lens. You can see every hair on the girl's head.

Take a crop from the top of her head. The indivual stray hairs look crisp.

Ok, I don't get it. What's the gag? It's not April fools day again already is it? :rolleyes:

That last post does look like you are front focusing a bit, but that shot of the girl looks pretty sharp to me.

That picture of the girl was one of 4 pictures I took and that was the best one in focus. All other pictures are like they are ever front focusing or out of focus, if you look at the focus chart I just posted that was on a trypod and its out of focus? any idears will I have to send this back.

I rely on focus charts like I rely on my government to spend my tax money wisely and thrifty.

In the real-world shot, the one of the girl, the focus is perfect. If you don't like the way it's focusing then take the lens back or get ready to send the whole mess back to Canon and be without for at least 2 weeks.

Even with the advances of AF, not every single shot will be in perfect focus. That's a simple fact of life. Yes, 99% of the shots like the one of the girl, should be in focus. Post one of the OOF shots along with focus point(s).
