Some of the gear from my 35mm kit is still in useable condition. I am thinking of the old lenses and flash. According to my manual, older Nikon lenses will fit on the new camera bodies, although some features will not be available. However, the manual does not mention anything about using any other flash types except the Speedlight series. I have a Vivitar 283 flash and was wondering if there would be any danger by putting it on the hotshoe and firing it from the camera? The 283 is a non-dedicated flash, so I would have to set the camera in manual mode, setting the shutter and aperture manually to match the flash. The camera I use is a Nikon D60. Thanks.
