Hello Friends,

Can someone recommend some of-the-shelf products for
recording 3000 rpm motion?

regards,
ali

300 rpm = 50 rps.

Casio developed a 300 fps P&S camera,

I would guess that the trick is in using a strobe light.

You might want to check your math on that one, 300 rpm = 5 rps.

Use A Tripod and Manual settings.
Focus sharply on the subject.
Reduce light level to nearly dark.
Set ISO=100, f=4.0, speed = 1/100 sec. and flash ON
If the on-camera flash does not have a short enough duration to stop the
motion, change the speed to 1.0 second and turn the flash OFF.
Manually trip a powerful off-camera flash immediately after you trip the
shutter.
An off camera flash with a G.N. of 100+ will typically have a flash
duration as low as 1/5,000 - 1/10,000 sec.
