How to turn off the flash of Nikon D70s? How to disassemble the lens?

There is a button in front of the left. Press it first, then hold the metal part of the lens, that is, the part combined with the fuselage, and slowly rotate the lens to the left. There is a white spot under the flash, that is, under the lens, rotating to the left. Be careful, it will fall off naturally! When installing, the program is reversed. The flash always pops up automatically, which is why you use automatic gear. The automatic gear automatically detects that your current shooting light is insufficient, and I will prepare a flash for you! Automatic SLR cameras are all like this. They have the function of automatic metering, but they need professional skills. So why take apart the lens? Be careful of the photosensitive components inside, and don't fall into the dust. Happy New Year!
