noise (shot posted with settings) UPDATED WITH SOOC

Not sure if this is my lens or something I am doing. If you look at this shot it's blurry/noisy I did have her twirl around but with my ss as high as it was that movement should not have been a problem. I also noticed this on a few others from this day that one image was sharp and the next in the same spot 2 secs later was blurry? Any advice on if this was something on my end cause I get it from time to time. I was thinking maybe I am slightly twisting my lens when I am shooting throwing the focus off but I tried watching for that so I don't think that is it? This was shot around 4 so there was light out but not bright sun.
ss 1/640 f/2.8 iso 400 48mm I also shot at a smaller ap to focus more but still had this issue?

It's your AP. With her moving like that, she's moving slightly OOF because the window is too thin. Try bumping up your ISO and closing up your AP, and you should see results you like better Smile

It's not motion blur, you missed focus. It hit in front of here eyes. You can see that the scarf she is holding is sharp.

Oh, and it looks as though it may be underexposed...hence the extra noise. It would be better for you to post the SOOC so we can really see what happened when you shot it.

Here is the sooc. I shoulda posted this one you are right. Even when I click on the scarf it is blurry to me. You can probably see it better in the sooc.

So did I miss focus then on the whole pic?
Stephanie I will try to bump up the iso as well and close my ap up some more.

Looking at it large on Flickr, looks like the focus fell on the scarf. And at that AP, it caused her to go OOF. Now, with a more closed AP, say around f/4 or f/5, you probably would have had the entire image in focus. That's not to say that having an open AP is not a possibility, but because she was moving, there's a higher chance that she will move out of the focal plane. Does that make sense?

If it's the bokeh you were looking for with an open AP like that, you could get the effect you were looking for with a longer lens. If you had a long focal length, pulled her far from the background, and closed up to f/4 or f/5, you would get her to stand out nicely. Here's an example of the compression that a long focal length will give you compared to a shorter focal length:

55mm f/4:

250mm f/5.6:

Exact same spot, just longer focal length, and me stepping back quite a bit to get it about the same size in the frame. Look at the difference in the background! I love long focal lengths, but hate how far back I have to stand with them. I'm always torn about my 55-250mm lens.

Sounds like you already have some great advice! Keep practicing!

Okay now I see what Amber was first saying about the scarf. Yes she was right and thanks Steph for that great post I really appreciate it!
Just got to see it now as my babies are down with fevers:(
I was using my tamron 28 75mm 2.8 lens. I am looking at the white lens that baby makes me drool lol! (CANON 70 200 2.8 L lens)
I was just thinking is it silly to buy a lens more expensive than my camera but when I ask myself which I would rather have I always choose the lens. My boss shoots with the 5dmark ii but he is upgrading to the mark iii when he gets back and said he wants me using his mark ii so really I think I will get comfortable with that first.
Now just to convince dh to let me get the lens. It's wrestling season with Tyson so I am thinking to use that as my pitch lol!
