Just got a new Kodak Pixpro FZ41 and it says memory full. How do I clear out?

Because that card is Waaaay beyond the specs! Did you read the manual??

The memory card (SD/SDHC) is
optional and not included in all
camera packaging. It needs to be
purchased separately. Please use an
original memory card which is Class
4 or higher and has a capacity of
4GB to 32GB.

the problem may be the SD card if it's am micro or more than 32 GB it is incompatible with the camera

here is the note from the manual for pixpro AZ421

A standard SD memory card is not included in the camera packaging and needs to be purchased separately. This camera takes a standard (SD/SDHC) memory card. We recommend using a name brand memory card that is Class 4 or higher and has a capacity of 4GB to 32GB. The camera is not compatible with Micro SD, Ultra, Ultra Plus, Extreme, XC, or adapters for any of these other memory cards.

P81 of the manual will show you how to format the memory card:

If the camera manual states it takes an SD card, then that is what you want. Be careful and do not get an SDHC card if the camera cannot utilise it - your camera manual should help with this.

This sometimes indicates that the exposure is correct for the distance of the subject. Remember that the flash on your camera is really only effective up to 3 - 4 meters

Call Kodak at this #.... 1-800-822-1414

Put the camera in 'Live Mode'

You need to put the micro card ( small ) in the adapter ( big ) if not it could be your camera
