>Have to say that I feel Nikon couldn't care less once they have sold their products. Your profile says you are very pleased with your Nikon gear It also says you shoot mainly under water - not a common photographic activity. It requires a waterproof housing to keep the camera and lens dry.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
