Cameras and everything else. Nikon has historically been known for it’s design excellence for good reason. The company has a good record for producing the kinds of products that have done well. What’s interesting is that unlike so many companies Nikon hasn’t tried to diversify our of it’s strength in optical products. They are, though very good at what they do.
Back in 2003 Canon put up a tutorial on how to block out a camera prototype in balsa wood to test look and feel. They have since pulled the tutorial from their website but I found a more or less complete copy.
