I have a Canon 40D and have been using an MP-E 65 lens with a 580 mk 11 flash. When I have the flash switched on I notice my shutter speed will not go any higher that 1/250. Is this normal?
Regards

    Yes. 1/250 is the maximum synch speed. However, if you set the flash for high-speed synch, you can shoot at a faster shutter speed. It works a little differently--instead of a single pulse, the flash puts out continuous low-power bursts while the shutter is open.

    Hope this helps.

    Thanks Richard, very helpful indeed. For example if I was taking water droplets from a tap would you recommend I increase the shutter speed.

    If you want to stop the flowing water sharply, you may well need a shutter speed near 1/2000th ( one two thousandth ) and that will require High Speed Synch. Your manual will explain how to set to HSS.
