I used to do photography with a 35mm camera but realizing editing a printed photo in photoshop renders me a subpar outcome half of my goals, I want to move onto something bigger and better.

Being said, I saw the commercial for the new Nikon D5100 with the filter to select it to be black and white but only show the color of a selected color in the photo or video (find the commercial on youtube, youll get what im saying). I dont think buying a $1200 complete camera for that sole function and 16mp, is there any other camera with that kind of filter that anyone knows of?
