Quantaray QDC-NK i TTL Digital Flash Module

It will work, but not all functions will be availale. You can buy a Canon module for the flash.

There is no problem with the trigger voltage, which I assume is your primary concern. You may not get all of the features you would with a Nikon flash, but you should be able to use it with the D60 just as you use it with the N80.

The QTB 7500A will work with the D90. However, you will not be able to use the iTTL mode of the D90. Use it exactly the same way you've been using it with the N80, letting the flash control the exposure.

Go to photo.net for a more comprehensive answer on this unit. But you should have a "slave" setting. May be called an optical trigger. You will need another flash to set it off though.

Yes it should. D90 has remote facility too.

You'll need the "AF module CN", but as the flash is no longer made will have trouble finding one.

It helps if you search for the correct flash model as Quantaray is a no-name bit of badge engineering for Ritz/Wolf.

Your flash is really a ProMaster FTD5700.

This is probably way too late for the original asker, but the previous answer is incorrect.

The Quantaray QTB-9500A is in reality a ProMaster FTD-5700 and was designed for use with later model electronic 35mm AF models (using the correct dedication module).

As such, the trigger voltage is no higher than 5v making it safe for use on later digital SLR's.

The original answerer is clearly aware that high trigger voltages on flashes designed for earlier, mostly mechanical, 35mm film cameras are often harmful to later models, but you need not worry about your model.

Suggestion: Before to spend any money in this direction, try to clean the electric contacts and be sure that batteries are fresh and fully charged (a voltmeter can help).

Having the same problem with the Quantaray 7500A and my Sony Alpha 200. I either have to go to full manual or overexposed. I've sent off a few emails to Ritz but still haven't gotten a reply.
