just wondering what these kinds of shutter speeds are for? where would one need these kinds of speeds?

just curious...

Things like stopping really fast action - some examples I've seen, water droplets into a larger pool of water, or milk splashing onto a model's body.

Ive used 1/2000 & 1/4000 to freeze the surf splashing over rocks. These shutter speeds freeze action but sometimes it can also look unnatural like in some sports shots where cars have there wheels frozen and it doesnt look they are moving etc.

Another reason is to enable the use of a wide aperture for depth of field control, outside on a bright sunny day. Extending the sunny/16 rule, 1/8000 is about right at F1.8, ISO100.

Cheers

1/8000th is still very slow for under f/2 shots in a very bright sunny day.

These were shot at 1/8000@f/1.4 + a CPL on top, yet still have to pull exposure down from RAW...

That is, 1/8000 for extreme DOF + speed under bright lights, freezes just about anything apart from a bullet.

Have you tried this Yi-P?..

I disagree - at ISO100, it's about right at f1.8! Of course, if you're shooting reflective objects, (such as water droplets sparkling in the sunlight) and don't want them to look overcooked in the final print, you will need to use less exposure.

But..... my D70 does ISO200 only

And my FM2 only does 1/4000 - but it will do ISO12
