Casio Exilim 5.0 mega pixels EX-Z57. My 2 yr old grandson got the camera this am and brought it to me. He apparently turned it on and tried to close the lens that opened. The 2nd lense from the from is cracked and the camera will not close! What can I do? I paid over $300. for this camera. Thank you! Jo Ann Hansen

Hi - sorry but this is a very old camera - nice in its day (I had one) but now so out of date.
Any camera which extends the lens is prone to disaster if the lens is knocked when extended - you don't need a grandson to do that either. Any slight fall will knock the lens out of alignment - each sections runs in a very fine twisting in/out circular track as they move - a knock will move all or part out of its track. Sometime you can be lucky and press (straighten) the lens so that its back in alignment - mostly not tho.
Given its age, and the vastly improved cameras out there now at far cheaper prices that we paid 12-15 years ago, suggest you remove the memory card and battery, and give him the camera to play with!. Go get yourself a replacement - if you want a camera which does not extend the lens, that will sit flat in your pocket/purse, even when on, consider the likes (or similar) of the Sony Cybershot DSC-TX55. - great camera - (more like a powder compact as the lens does not extend.)
I have one can so can recommend. Other brands have similar 'flat' cameras also. Save more dollars - find a nice secondhand one on ebay or similar. To use, all you do is sllde the front plate down and you are off.
Cheers - have fun taking pics of that g/son.
