Just wondered if anyone else ever has this problem?

I have taken about 4000 shots with the camera; and do find/ have always found that about 1 in 10 shots misses the focus (When using autofocus) on what should be very easy shots. e.g. I was taking a few shots on my kids in the pool in the back garden , no zoom, iso 100, shutter speed was 1/30 and out of the 12 shots I took 2 completely missed the focus.

here is an example:


thanks

I looked at the picture and it seems to me thatthe camerafocused on the swimming pool wallbehind the girl. The junction where the Yellow meets the Red and all the section behind the face of the girl is sharp. I don't think you have a problem with the camera. Do you use spotfocusing or other mode?

I agree. The area behind the girl is infocus. You should use spot focus.

Hi all

Just to clarify, the picture above was taken in Auto mode , and as far as I can see I cannot change to spot focus.



I have taken pics in many different camera modes and to be honest the resulkts can still be a little hit and miss in the same fashion.



any advice is welcomed

Like you said: Inauto mode you can't change to spot-focus, so put it in manual mode then turn it on to spot mode, make sure the spot focuses on the subject you want to take a picture of......

Hi Rudo

this is indeed what i often find myself doing, however several other people use my camera too; and they really just want to be able to point and shoot. As for ensuring that the spot focusses on the desired area, well that go's without saying.....



Just as I'm writing this a colleague, and much esteemed photorapher has identified the possible problem.... "Hawking"...i.e. because there is not enough texture differentiation at the centre of the image the auto focus drifts in and out of sharp focus....

For whatever the reason ....the exif says (1/250 sec exposure) but there is some motion blur especially in the childs hand.....but to get a better sucess at focusing,

Change the mode to program ...almost as fool proof as Auto and the settings can be tweaked.

And if your using C-AF, turn it off....It does not work the same as on a DSLR.

ok will try the tips.



Indeed this one was taken at 1/250... and my daughter was all but stationary, ntl at 1/250 wouldnt have expected blur to this extent

(as I say out of 4000 shots I have a fair few hundred like this)

At that speed ,I also would not expect to see motion blur but it sure looks like motion blur in the hand....I just really do not find C-AF to be helpful on the FZ cameras nor do I find the 9 pt AF to be useful. I like the 1 area fast focus, but it does miss focus at times.

It is hard for an autofocus system tofind the strongest contrast edges in a moving subject.
