This memory card is not compatible with the FinePix S2950 .
Your cameras will not accept the type 'SDXC' and/or 64gb cards. The cameras need the type 'SDHC' with a maximum 32gb card.
I purchased this memory card and when it did not work I went to the FujiFilm website to find out if it was compatible. It took some effort to find this information; first my owner's manual had the wrong website link to the list of compatible memory cards. I did a search on the website to get to the list; the memory card information is the same for your S2950 and my S2900.

Best Buy allowed my to return the memory card and I purchased the SanDisk Ultra Plus 32gb memory card and haven't had any problems.
