sony a390 DSLR focus problems

[just jon]

When I put my camera on Auto mode and I focus Manually . When i am looking through the view finder a light comes on when in focus but it very precice if it is slightly out of focus the shutter button will not press . Also if the lens is on AF and camera is Auto if i focus on an object if the camera ever so slightly moves due to shaks the button cannot be pressed .

Does that only happen with my camera or does every camera .

At a guess, there's a setting in the menus that allows you to choose whether the camera's shutter will release if focus isn't confirmed. Either turn this on/off or set the focus mode to continuous rather than single shot (or whatever Sony's version is) so it can continually autofocus. However, I'm a Nikon user so your make may be different. Hope you get it sorted. (P.S.) A good read of the manual should tell you how to alter these settings.

Will read the manual again and see if i can change it . on the dial for(A)AUTO,(P)PROGRAM AUTO,(A)APERTURE PRIORITY,(S)SHUTTER PRIORITY,(M)MANUAL
If i put it on (P) it will do everything auto does but allows for changes THAT SOLVES THE PROBLEM .
