Re: Auto Focus Problem
It´s pretty normal on that camera model, there was a problem on the focus system and they are fixing it when u send to a repair centre, they just don´t say it, but once u send it they will repair it, and will be fine.

Are you sure you did not put the AF/ MF switch in the wrong position? Although I don't think it would focus in Auto mode. In all other modes, are you sure you selected a (or more) focus point(s) in the centre of the frame?
When the selected focus point is on the side of the frame it won't focus on the parts you want it to focus. Then while pointing to the point you want the camera to focus, please press the shutter release button half and what till it focusses. Then press it the whole way down. Be aware the camera needs enough light to focus and certainly can't focus with a lens wit a min aperture of 6 or a larger number. On your 18-135 you can shoot at f16 because it will first focus on wide open and only close the aperture after you pressed the button.
There are no rules or conventions for this. It is totally up to you to chose which method to use.
Sometimes when taking images in close up where a leaf or stalk may invoke autofocus to lock onto the wrong object to get a clear pic, then select manual so your subject is in focus
Depth Of Field is also associated with focusing, autofocus does not always deal well ith DOF situations. It might be better for you to get a simple book on digital photography to help you understand how to get the best results from your camera
The lock that's around the 4-way button that moves the AF point will stop it from moving. The AF switch (says C,S,M) on the body below the lens release button gets knocked to manual and turns off the AF
The camera is having problems with your lens and this is why it goues into the error mode. Try first cleaning the interface contacts on the lens ( see enclosed pic ) . If this does not sort the problem out then the auto focus motor ( or related hardware ) inside the lens will need attention. Also try other lenses to see whether it is only the lens ( I very seldom see this sort of problem cause by the body ; it is always the lens that gives this sort of trouble )
iESP is the default auto focus setting for the C-8080 Wide Zoom camera. It uses a contrast detecting system to analyze the entire image by comparing the subject against the background to achieve focus. When the shutter button is pressed half way on the C-8080 Wide Zoom, the AF target mark automatically moves to an area of the image where it finds the optimal contrast.
iESP is the default auto focus setting for the C-5060 Wide Zoom camera. It uses a contrast detecting system, to analyze the entire image by comparing the subject against the background to achieve focus. When the shutter button is pressed half way on the C-5060 Wide Zoom, the AF target zone automatically moves the to an area of the image where it finds the optimal contrast.
All auto-focus systems need a fair amount of light or contrast to work efficiently. If possible, raise the ambient light if indoors. Search for an area within the desired focusing point with contrast to focus on.
