Why doesn't Nikon sell fisheye lens?

So I was wondering. Why doesn't Nikon OR Canon sell fisheye lens? You can purchase the lens at a store like B&H but when I go onto the Nikon or Canon store they don't sell it.

I wasn't aware that Nikon and Canon has proprietary stores. Small dealers probably just don't carry that lens because it doesn't sell very well. They can't afford to have an inventory of stuff that doesn't sell. What's the point in complaining if you can order one?

They do.

There's a DX 10.5 mm fisheye used on all Nikon APS-C sensored cameras and the 16 mm fisheye for FX and 35 mm SLR cameras

Here is a complete list of current Nikkor lenses

The Nikon stores only sell selected cameras and lenses. Whether you buy from the Nikon or Canon store, there's NO discount on any of the offered products. You can look for refurbished lenses and cameras on the Nikon site, however you will have to check back daily in order to find what you want since those items are sold at a rapid rate.

They both sell fisheye lenses.

They both do.
