Nikon D200

Please can anyone help.

I fitted my old Nikon SB-26 flash to my new Nikon D200. The safety lock on the hotshoe
will not allow me remove the flash, What can I do ?

If it were me, I would take it to a good camera repair shop and have it removed. In my opinion, if you try to remove it yourself, you could break something expensive. Pay me now, or pay me later (and maybe a high price later). Just my opinion.

I'll second the idea of going to a shop. It may be something simple - which I'm guessing it is. If you force it, you could break something. Most likely it would be the plastic hotshoe base of the flash which wouldn't be too expensive to fix, but if something broke on the camera the story would be different.
