Speedlight SB-22S TTL Flash: i have a Nikon Speedlight SB 22 that was used on m...

You should be able to use your SB-22 with your D5000, however you can only use it in the manual mode since it is not a TTL speed light. That means you will need to manually set both the camera and the flash unit. I have done that successfully with an SB-25 on both my D800 and D90 in a pinch, but you should consider investing in either an SB-700 or SB-910. They are allot more versatile.

If you're worried about the trigger voltage, it's safe according to this list: http://www.botzilla.com/photo/strobeVolts.html

You won't get all of the automation as you would with a flash intended to be used with a Sony camera.

this flash will not work on the newer digital nikon cameras, the flash for d90 needs to be ittl compatible.

No--SB-400, SB-600, SB-800, SB-700 or SB-900.

Yes, but not all features may work. Look in the manual under "Optional Accessories."

I think you will need to upgrade to the 22s. It sounds like the newer model provides the D60 with a 'handshake' signal that the older 22 model does not have.

the SB-22 has a voltage of around 4.5v this means that it will not fry you D60 SLR so the answer is YES you can use you old flash gun with your D60

WHICH FLASH I CAN USE FOR MY NIKON D60

in the manual setting the SB-22s is just a standard flash and should work with a standard hotshoe.
