Do you have a Nikon SLR camera?

No. Don't say it's a SLR, it's just a small DC, and there are no knockoffs (those knockoffs with cameras and DC cases don't count)

SLR is very sophisticated, involving many technologies and patents, and needs a lot of investment to make it, and the market is not special, and no cottage manufacturers are interested.

However, there is a plan: buy a cheaper Nikon SLR (such as Nikon D70), add a vertical handle, then cover the D70 logo with black tape, cover the focus assist light, spray "D3s", and make some other decorations. After some dressing up, the D70 can look a bit like the D3s.
