Originally posted by D1N0 It is telling us something about the direction photography is going in. Also whatever list you check, Canon is on top. Amazon lists tend to top whatever is cheap and being dumped. How many of those rebels end up on shelves and in closets? A dedicated camera store is more likely to show which way enthusiast shooters are moving.
I'm not sure that "photography" can be said to have a direction. Sure, the basic sensor technology can have a direction (more megapickles, more ISO, more FPS). But people who take photographs aren't all wanting the same thing. The absolute vast majority of people who take photographs want an inexpensive convenient pocketable automagical box for snapshots. They abhor all the arcane details of aperture, shutter speed, ISO, white balance, DoF, flash, etc. that enthusiasts actively seek to understand and control.
The "enthusiast" segment is an even more diverse group divided by genres of images: BiF/wildlife shooters, landscape, portraiture, studio, macro, astro, etc. And then there are the tech-gadget-du-jour lovers and folks who just want the most expensive camera possible to show off how rich they are. Moreover, the enthusiast (unlike the snapshot shooter) as the knowledge to know exactly what equipment they want and they have willingness to pay for niche cameras, lenses, and accessories. Enthusiasts drive photography in a dozen different directions.
We can agree that Canon is on top -- they have 28 entries in the Amazon top 50 (Nikon has 6, Sony has only 3). But even Canon shows no single direction in that Canon's popular products span the range of compact, bridge, cheap DSLR, $$$$ proDSLR, MILC, and dedicated video cameras.
And there's still the issue that Japan is just different. They are actually on the trailing edge of sales trends in compact cameras, for example. Of course, you can argue that Americans (and Amazon) are different too, But then that is my overall point that there simply is not a unified photography market with a unified direction.
