is Ninon Flash compatible with Pentax cameras?

[freeradical]

I found this:

The SB-20 is not just useful for Nikon SLRs with TTL flash; it is also a low-cost, high-power, high-reliability flash for multiple cameras:

-- Its low synch voltage and variable power output make it a natural match for the Konica Hexar AF, which is able to take advantage of low, low power in its programmed flash mode. If you are using 400 film and can't get close enough with the HX-14, you can use the SB-20 on 1/16 mode and set the GN as low as 2 (meters). Then you can shoot at 0.6m and f/6.7. Just remember to set the flash to the -7 deflection.

-- The Konica Hexar RF comes with a pretty small flash. The SB-20 will trigger the flash ready indicator and set the synch speed in AE or AE-L mode. The multiple auto modes help.

-- The Fuji Finepix S2 can use the SB-20 for TTL operation, since unlike the Nikon digital SLRs, it can use conventional TTL flashes.

-- If you don't have a TTL flash Leica (so if you have a Leica M4-2 through Classic M6), you can use the SB-20 in manual or automatic.

In sum, you can use the SB-20 on anything that has a conventional hot-shoe flash connection.
