#1. "RE: Display only NEFs on playback?" In response to Reply # 0
Migs, Note there is a difference between playback and image review. Your question mentions playback, but I think you are referring to the image review function that shows each image automatically after each shot. I tested image review on my D800 set exactly like you have yours, and it does the same thing - both are displayed. Since it is either on or off with no other functional options, I don't see a way around it to check imagaes as you shoot. But you can use the playback function as a workaround since that pulls from one folder at a time allowing you to scroll through just the NEF files on your CF card - you just have to push the playback button to get there.

Thank you friends.
I was indeed referring to reviewing (scrolling through) the images on the camera display. The Folder to current doesn't solve the problem. The only almost perfect way to do this is to set NEF on both the primary and secondary storage cards. I really don't use the jpegs anyway.
Thanks for you all's help.
