In this video we compare Nikon's most recent 35mm lens - the f/1.4 G AF-S - and compare it to the much cheaper, older f/2 AF-D lens, to see what the big difference between the two lenses really are. Can the G be that much better? Or is are you just paying for the larger aperture? Watch the video to find out.
