Yes.
Halos can also be caused by condensation (dew?) on the lens and/or sensor if you move between places with big temperature differences like car-outdoors or home-outdoors in cold weather.
This kind of halo usually disappears waiting for temperature stabilization between the camera and environment. It may take up to an hour in some cases.
But we are just guessing until we see some image sample.
Yes thats true 
,
However the poster indicated that Auto resulted in generally good shots (when they worked), some shots 20 of them came out okay. This would seem to indicate user error as i would think condensation would affect all modes.

All your photos will be arranged horizontally along the bottom of your zoombrowser right window and you will have information tabs along the right such as File informatiion, star rating, keywords, shooting information....

**** There is a general rule of thumb that if you shoot below a shutter speed of 1/60sec (As will be indicated by the handshake icon on camera)... then you will need to be very careful not to shake the camera when taking the pic... tripoding as others suggest is needed, or even a monopod. With practise youll learn to get away with as little as 1/15sec..
To get your shutter speed up to a higher value you will have to either decreas the AV value (opening up the lens) at the expense of loosing depth of field, or increasing your iso upwards tp 100,200,400 from 50 (at the expense of noisier grainier images. There are things to check such as ND filter is off. An "ON" setting has the effect of closing your aperture by 2 stops from memory which causes your shutter speed slower.
Ive tried not to bother you with details, youll pick them up soon enough if you ask enough questions on these forums.. plenty of helpful people and advice.
