Hello and welcome to JustAnswer, I look forward to assisting you today. Has your camera sustained any damage that you are aware of?
Look closely at the lens to see if it looks even all the way around.
Okay try this. Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The camera will try to autofocus while the lens is attempting to extend. You may need to try this a couple of times to get the lens to cycle.
Okay, the next thing I would like you to try is this. Remove the memory card and keep it removed, then remove and reinstall the batteries. When you turn the camera on with the card removed it may trigger a reset and engage the lens. If that works, turn the camera off and reinstall your memory card.
Try blowing compressed air in the gaps around the lens barrels with the idea of blowing out any sand or grit that may be in there jamming the lens. If you don't have any compressed air, try cycling the power and as you do gently try pulling the lens out with your fingers. You may need to do this several times as well.
Do you have the compressed air?
Is the lens completely retracted?
Try moving it side to side while you cycle the power.
Did it feel like it was stuck or did it move freely?
Can you try pulling it out to see if you can re-align it?
Okay. I think we are beyond anything you will be able to do to correct this. You could take it to a repair shop, but the repair will probably cost as much as a new camera.
You’re very welcome. It was a pleasure working with you!
