I have a Nikon Speedlight SB-15 that I purchased somewhere in the early '80s for use with my Nikon FE2 SLR camera. The flash had automatic modes to work with the camera, as well as a manual mode. I just purchased a Nikon D5100 D-SLR. Does anyone know if I can use the Speedlight with it?
Welcome to Nikonians! Since the SB-15 is limited to Non-TTL Auto flash mode and Manual flash mode when mounted on a DSLR you should use Manual exposure mode and Manual ISO for the most consistant results.
After attaching the Speedlight SB-15 to the camera, I set the Speedlight to one of the two auto (non-TTL) settings. The flash fires, but the camera is using a very slow shutter speed, like 2 seconds. The camera is set on P. What am I doing wrong?
As I wrote above, set the camera in Manual exposure mode. Also set the ISO to Manual as well. Then set the shutter speed on your D5100 to 1/200 sec. or slower. Use the calculator in on the SB-15 to set the aperture (f/#) based on the flash to subject distance and the ISO (ASA) you have set in the camera and flash calculator.
Great! In non-TTL Auto flash mode, the sensor built into the flash unit will cut the flash power once it "sees" enough light for a correct exposure based on the Aperture setting indicated on the Speedlight. While i-TTL flash control is much more user friendly, non-TTL flash control is accurate as long as you keep the flash to subject distance within the range indicated in the flash calculator.

So it sounds like I should put the camera on M, set the shutter speed to 1/200 or slower, and set the aperture to whatever scale I'm using on the flash. But then is it necessary to set the flash on M? Or can I set the flash on A and let the flash read the light as you mentioned above? By the way, this flash has two A settings.
***Disgard. You answered my question in your previous post: use non-TTL Auto. Thanks again.

I just remembered that my FE2 camera would automatically set the shutter speed to something appropriate when the flash was turned on. Obviously the D5100 won't do that with this flash. I think I was expecting it to...duh! Therein lies my original problem.
Thanks for all your help. Now I can go to bed less stupid!
Over the years, Nikon has had three distinct TTL flash control systems. 1. The original TTL flash control system that was deisgned for Film cameras.
2. (Digital) D-TTL flash control used by the early DSLR's like the D1 series and D100.
3. (intelligent) i-TTL flash control system introduced with the D2 series and D70 bodies and continues to be used today.
The problem is all three systems are completely different and are not compatible with each other.
That said, to add a little confusion: The SB-_ _ DX Speedlights with a DX suffix use D-TTL flash control but are backwards compatible to film TTL. The first generation of i-TTL Speedlights (SB-600, SB-800) are backwards compatible with both D-TTL flash control and film TTL flash control. The D2 series are i-TTL compatible and backwards compatible to D-TTL flash control. The F6 is i-TTL compatible and backwards compatible to film TTL. The discontinued SB-900 and current SB-400, SB-700, and SB-910 use i-TTL flash control and have no backwards compatibility.
Over the years most of the higher end Speedlights have one version of TTL flash control, AA or Non-TTL Auto flash control, and Manual flash mode. The entry level Speedlights have one version of TTL flash control and Manual flash mode.

I own and use two sb-15 flashes on my Nikon cameras. I use manual mode or aperture priority on the camera and "A" mode on the flash. Motor drive "MD" mode and "TTL" will not work properly. I have found strangely enough that "A" position, "A2" on top switch, camera set to 1/60 and F8 will work with every lens I own. May be a bit dark or light, but is always a good place to start. This also works on my film cameras, they usually are a little dark and I open up about one stop. I keep my cameras on about 400 ISO. You can also leave camera on "P", auto and A2 position on flash and it will work well with 28 to 50mm lenses. Tried with primes and zoom. Works on D1,D2,D100 and my D40 and D70 Bodies. For some reason D60 Overexposes slightly.
