"I seem to be confused "


US
          

I have a D90 and an aftermarket Nissen Ittl flash. works great with cpu lenses. Not go with Ais lenses. I know older flashes can fry the electronics in the D90. Some one told me I can safely use a SB28 a Nikon film era flash. Is that so, Is there a way to test a flash with a meter to verify it will not put out a harmful voltage. Can anyone point me to reference material on using older non Ittl flashes safely?

I have a sunpak flash with a Nikon module that I got when I bought a film camera for it's lens. I just don't know enough and the books I have on the D90 only deal with Ittl etc. thanks in advance for any info or referals. JB

Hi John,

Since the D90 does not support metering with non-CPU lenses I-TTL flash control is not supported.

If your Nissin Speedlight has Non-TTL Auto flash mode or Manual flash mode you can use either of the two modes with your D90 in Manual exposure mode.

Yes, the SB-28 is safe to use on your D90 though again you will be limited to using Non-TTL Auto mode or Manual flash mode. Film TTL flash control, D-TTL flash control, and i-TTL flash control are entirely different systems and are not compatible with each other.
When I get to a computer I will give you a link for testing the sync voltage of your Speedlights.

Best Regards,
Marty

Thanks I would like to test my flash and one I have on hand to feel more comfortable. Someone on the "Manual Lens" forum sent me a link to a table with various flash manufacturers and their tested voltage.

Hi John,

Here is the link with the instructions for testing the sync votage.
You will see the instructions about 1/3 of the way down.
