Ignore the Projekt,Is there a G9 equivalent manufactured by Nikon?
Nikon makes great Cameras and Nikon and Canon are largely equivalent. Think Ford VS Chevy or Suzuki VS Kawasaki. They are pretty much even and one usually has an answer for the other every step of the way.
That being said NO, I do not believe that Nikon currently makes a Compact "Viewfinder" type of all metal bodied 12MEG feature rich camera to equal the G9 or the Elph line of cameras. Point for point I would say Canon is ahead of the rest on this front.
Where Nikon holds an advantage I believe is in the SLRs. They have some terrific lenses, and bodies, but Canon does as well... So yeah
But Projekt is largely yanking your chain...
