My camera lens is stuck. Is there any way I can fix this on my own?

The PNY memory card is not on the list of compatible SD cards. However if the SanDisk card is an SDHC memory card, then it should be compatible. If this does not help, please reference the troubleshooting page for some other solutions. There is also a link to the device manual under "Incorrect SD Card type" where you can find the memory cards supported by your camera. The troubleshooting page can be found here.
