I am upgrading my camera but not sure what too. My choice is either a Nikon D90 or a Fuji S5. I currently have a Nikon D40x and the lenses are compatible so I just need the body. I can get a S5 for £420 and a D90 for £650. I use Aperture a lot. I have 2 concerns, 1. Does Aperture work ok with the Fuji RAW file format and 2. What is the best camera to take portrait and landscape shots? Any thoughts welcome.
