Do you have any intentions of using the video mode? Nikon lists this camera as being capable of 1080p and you might not be able to utilize that feature with slower card. In the past the video mode on still cameras was a nice gimmick but I've seen some samples from the Canon DSLR's and it was fantastic.

Before one invests in faster cards just for video, especially is cost is a concern, I would try to find out if Nikon has a particular memory speed they require for video. The reason I say this is because I shoot a fair amount of video with my Canon DSLRs, and haven't noticed any problems even with my slowest cards. That makes sense because video frames are much smaller than pictures, plus video is compressed. It's just not as bad as one might think.

You're using 1080P on highest setting?

With 1080P for minimal quality I would suggest you need something in the 8mbps range, if you want to make a comparison typical blu ray video is going to be 25mbps. Flash Camcorders on highest setting are going to be in the 12 to 15 mbps range or whatever the the fastest card is, HDV camcorder using tape is in 25mbps range but the codec isn't as efficient as those used for flash. For really good HD video you need something with a significant data transfer rate.

Yes, I shoot 1080P. You may be right about the required speed though because my slowest card is 15 mb/s.

Shooting video doesn't demand as much speed as high resolution images do. The buffer size in the camera also matters.

A Class 10 SDHC is rated as such for having a minimum sustained transfer rate of 10 MB/s, while the maximum transfer rate can vary and is usually somewhere between 15 MB/s and 30 MB/s.

My SanDisk 16 GB Class 10 has a maximum 30 MB/s transfer rate and it is visibly faster than Lexar 8 GB Class 10 (probably 15 MB/s max) when taking images in burst mode (such as taking 20 shots in couple of seconds in RAW+JPG mode) but I haven't noticed any difference between the two in videography.

Right, this is my observation as well.

Sounds great! I don't really plan on buying any new SDHC cards until I figure the camera out a bit more, and learn how to use it better. I am just using my old 1GB, 2GB and 4GB cards that I used with the Canon P&S.

I really did not have any intentions of using the video capabilities at all but my wife says ''we'' are taking video of the grand kids no matter what, so I guess the answer is a definite yes now.

There is no right or wrong, depends on your needs. If you want high quality video 8mbps is nothing. If you want to put in the context of images it's like using 50% to 60% quality for .jpg images. Just like .jpg images video can have different compression levels which is determined by the data rate.

Sony A55 (my camera) records AVCHD (full HD 1920x1080p) at 17 MB/s and MP4/HD at 12 MB/s (1440x1080p). So while a Sandisk with 30 MB/s max transfer may deliver a sustained rate that will satisfy both better than may be another Class 10 with peak around 15-20 MB/s, I doubt the difference would be noticeable and it surely isn't. But then, I rarely shoot segments longer than 4-5 minutes at a time.

If you are shooting video, the card speed will definitely be a factor...
