I realize that this is an old thread but I would like to add my 2 cents. . .
I use the SB26 strobes with my Nikon DSLR cameras with excellent results. I always use the auto aperture setting and the accuracy of the sensor is amazing. Fill-flash is a snap: Simply use the ISO setting on the SB26 to fine-tune the amount of fill. (Of course, this requires using the manual settings on the camera.) Set the flash aperture one-stop faster than your camera e.g. f8 on the flash and f11 on the camera. Then increase the ISO speed in 1/3 stops to the desired amount of fill-flash. The amount of fill-flash will depend on the flash-to-subject distance but generally it will be between -1.0 to -2.0 stops. . . The amount of fill is up to you. Fortunately, now that we have a rear LCD on our DSLRs it is easy to confirm the amount of fill before committing to a specific setting.
In quickly changing light this technique requires a little extra time to accomplish. But 99% of the time I am shooting when the ambient light is constant so it isn't a significant real-world problem.
