K10d: 1/4000sec?

**Syb** · 02-07-2008, 09:19 AM

I know that K10d shutter speed could be as fast as 1/4000s. I think I have never yet used it. Did you? When/where/why?

It is my humble opinion that more versatility in low light (=higher ISO) means much more than versatility in broad daylight.

Maybe it shows that it has been winter for too long now.

1/4000 is easly usable during daylight

also for sport shots, where its more important to stop action than anything else.

I was in Portugal last week and took some daylight shots with the sun bouning off the ocean. I used spot metering, aperture priority, and some were shot at 1/4000 of a second.

If you're using 1/4000s, it means you're not stopping down enough. If you need to use f/64, then so be it, but all shots must be taken no faster than 1/100s and SR kicking in like a wild stallion. The good folks at Pentax spent a lot of time designing the SR for us to go and shoot at 1/4000s; it's like a slap in their face!

apperantly SR is active even at 1/4000....

Uh, if it's bright outside and you want to shoot at f/2.8 (or even GASP f/1.4!)

I'm going to buy a Canon 40D and that goes up to 1/8000s!

1/4000 is really good to avoid effects of any shake or vibration.
I have used it to test sharpness of different lenses. I shot the glowing tungsten wire in a light bulb. In order to not overexpose, you really have to go for such exposure times.
And stopping down to f32 or something is not an option, since I personally don't care how sharp or unsharp a lens is at that kind of aperture. It's the faster apertures that interest me.
