simple. the focus is wrong. you focused on the hand instead of the character's eyes. in doing so, you might get a blur hand, thats when you have to decrease your aperture to get a wider DOF.

For this kind of small things, best is always use Manual focus, because the camera AF will be tricked at short distances, and low DOF. Also, traditionally people focus on the eyes, cos thats the first place you look when you see a face. Hope this helps.

If indeed you have used a single AF point positioned at the face then either the focus got distracted by something else (keep in mind the sensor is bigger than the point marking in your viewfinder) or you have shifted the camera after focusing (called Focus & Recompose).
In addition your Depth of Field appears very thin. Read more: Understanding Depth of Field - including calculator.

I can't see your pic. :dunno:

I can see the first one though and the subject looks pretty big (and it's obviously not moving...).

As I have mentioned in the other thread, I have no experience with Sigma lenses. I suspect that the quality of these lenses aren't very consistent though. You may want to check with Sigma.

However, the pics look ok-sharp. You can try a high pass filter in photoshop or any pp program you use to make the edges look sharper.

I saw that you shot at 52mm at f/4 on one of the shots. You were also using flash. The flash in this case is not helping you to isolate your subject from the messy background. To make the subject sharper, you should stop down (ie. use a bigger f number).

Try this:
1: change your metering to centre-weighted.
2: stop down lens to f/8
3: set your flash to high-sync ittl (ettl for canon?) mode
4: change your camera mode to manual
5: try 1/500s for your aperture speed

play around with the settings and see if you can get something you like more.

ya...i did play around the setting...it seem like the f stop higher give a sharper image...and i just use the normal bulit in flash and set it down to -2 as i just wanted to catch its eyes...
and with flash on...i cant make the shutter speed to 1/500s...the max is 1/200s...

when using 24-70mm at f 2.8...the pictures really blur however when i increase the f stop to f4...it improve better...

as for flash mode...is e-ttl II...and the shutter can set 1st curtain and 2nd curtain and the e-ttl II can change to evalutaive and average mode...

Find "high-sync" or "flash-sync" speed or something in your camera's manual. Can't help you there as I'm not familiar with Canon. You should be able to use any shutter speed you want with your flash if you set it right.

EXIF data. Ask Google and get tons of information. In a nutshell: your camera writes a lot of parameters about your camera settings (and others) into the image file.
