    A flash is a flash, shutter speed doesn't matter as far as the subject/s that are exposed by the flash are concerned. Shutter speed matters with how you're mixing with the ambient light. You'll want to shoot in Manual to control this.

    Not for the d40, d50, and d70 :bowdown:

    You can sync with a direct connection (pc cord to flash or a non ttl flash in the hotshoe or a ttl flash with the contact covered that communicates for ttl) at up to the maximum shutter speed.

    Using radio triggers you become limited by radio delay so they'll usually only work up to 1/1000 - 1/1250 or so.

    Excluding high speed sync, I think the max shutter speed sync is 1/500 on some cameras.

    See edit. This isn't focal plane high speed sync. You can trigger a non ttl flash directly connected and it will light properly up to the maximum shutter speed of the camera limited only by flash duration if the specific power setting of the flash is makes the duration longer than the shutter speed.

    Wow, talk about lots of misinformation.

    1. Shutter speed has zero effect on flash exposure. Flash exposure = aperture + ISO + flash to subject distance. Use shutter speed to control ambient light in the scene.

    2. The max flash sync speed is the shutter speed at which the entire sensor is exposed to light at one time. Go any faster than that, and the first and second shutter curtains create a "slit" that travels across the sensor. A single flash pulse will not light the frame evenly if you shoot faster than the max flash sync speed, so the camera limits the shutter speed.

    3. Focal plane flash, aka high-speed sync, fires a series of light pulses that light the frame as the two shutter curtains travel across the sensor. This allows you to shoot flash at shutter speeds above the max flash sync speed. The disadvantage is that flash power is decreased, so it won't work well at long distances.

    4. Some cameras with cheaper electronic shutters (D70, D40, etc.) will sync at any shutter speed. Typical max sync speed for cameras with mechanical shutters is 1/200 - 1/250.
