Hi
moonlustie
Best tips;
1. For close-up\macros - like Pooh. Always use a tripod to get sharp
images! The very close distances involved gives minimal depth of field -
that's in front of and behind the subject - in some cases measured in
millimetres! On top of this any camera shake - up and down - is greatly
exaggerated. You simply won't get anything sharp without one as the slightest camera movement registers blur! Also use remote
shutter release as well; your finger pressing the camera shutter will cause
enough movement to induce camera shake!
2. If doing anything hand-held, ensure that your shutter speed is the same as
the focal length that you are zooming to. i.e. if using 60mm, then 1/60th of a
second minimum must be used! If 200mm then 250th of a sec or
faster!
3. For macro\close-ups, always use manual focus to focus on subject's eyes. Most auto-focus
systems will struggle at these close distances and normally pic the wrong item
to focus on if in some sort of inteligent mode!

To your
images.
The Pooh
one you seem to have previously removed: His face and body are out of focus, buy
the CE label is almost nice and sharp! You need to get his eyes as your area of
focus. In this case, 'cos the label is sharp, camera shake is NOT the cause of blur,
it's the area that your camera has selected to focus on! You should really be in
manual mode for macros to keep control of it. If you were in manual, and you did
focus on his eyes, then it's possible you have a camera
fault?
The vase
pictures seem to have good depth of field and focus - almost from front of room
to rear.
The ISO
Pooh tests: clearly as you increase ISO, they get sharper. As you're in aperture
priority, your depth of focus is remaining constant - 'cos the aperture isn't
changing, and neither are your focal lengths and subject distances. As you increase ISO
in this AP mode, the camera will automatically increase your shutter speed to keep the same expouse -
it'll get faster each time and that's progressively managing to overcome,
what must in that case be - possible camera shake? Though if you were on a
tripod this shouldn't be that much - unless you've been pressing the shutter
release with your finger and not a cable release?
As you see
with the highest ISOs, horrendous noise comes in! Simply don't go this high. Most
people try to go no higher than ISO 400 and always 100 if
possible.
Hope this
helps?
Cheers,
Neil
