K-x High ISO Test Shots :- )

The first image is totally untouched. Shot JPG. Shot at ISO 12,800 and at 1/13

Used a Pentax K-x and a 16-45mm lens. Light was from a sealing fan above items shot. Nothing fancy at all.

Second shot is a copy of first but with Topaz DeNoise added. Set at 1.25 and a recover of .55

IMHO there is NOTHING Pentax has ever made that can do this. The high ISO is off the charts terrific. My K20D could only dream about doing this and my K200D could not even think about it :- )

This is truly OUTSTANDING performance IMHO.

Anyone is free to download and do any Photoshoping you want, this is not art, just a demo of this camera.

Pentax is to be congratulated on making a beginners camera a true monster, to bad the K-7 did not have this sensor :- (

Are you saying the K-x has a better sensor than the K-7?

I don't see any sense in photos at ISO3200-12800 at all.
The best resolution of camera are at ISO100-200.

K-x has lower noise than K-7. Yes. Just add a bit colour NR in LR, for example, and it makes K-7's photos at ISO1600 not worse than K-x, but with better resolution.

Well, sometimes I sit in the cheap seats at indoor events with the DA 50-150mm at f5.6. That's when I am shooting at ISO3200 and 1/250 to stop motion blur with my K100D, coming back probably one stop under exposed, and with a big PP job with the RAW file to bring back levels and kill noise. Now I don't need to do that to put food on the table. It's just one of my photo interests.

Higher ISO capability allows us guys with slower lenses to get pictures that would have been impossible prior.

qquake2lL, That de-noised shot sure is sweet. I ran the first one thru noiseware with similar results. I'm convinced that I want a K-X now.

True, but sometimes ISO 100-200 just isn't an option. Some may prefer not to take pictures in these conditions, or to alter the light to allow lower ISO, but some prefer to be able to shoot such scenes as they are.

I often find myself in shooting conditions where ISO 200 simply does not allow the necessary shutter speed and aperture combinations to achieve critical sharpness where it needs to be while handholding. Having an ISO 800 that's barely any noisier than base ISO is really quite useful.

800 and above is useful too, depending on your needs. Try telling a sports photographer or photo journalist or live music photographer or street photographer that they should stick to ISO 200.

And speaking as someone who was a film photographer for several decades, I welcome the new options DSLR's make available to me by delivering good IQ at ever higher ISO's. Sure I loved my Kodachrome 64 and Kodachrome 25, but I also like being able to play at 3200 ISO now too.

Anyway, I think ogl is just trolling again.

there is another angle to this whole high iso thingy.
The issue is that having bad high iso simply hurts sells. People dismiss camera by saying that it does not have good high iso ability and hence should buy competitors.
Canon for last few years had been selling good amount of cams with punch line of king of high isos.

People use high isos images or not but having a camera performing good at high isos (even with NR) is good thing for business. Reviewers like dpr who test cams on default settings won't be able to diss this pentax this time.

hehe this reminded me of this one person asking to see my camera after seeing it was white and unique. She didn't speak the best english, and asked something about high iso. I put it on Sv and went to 12800 and she took a shot. She zoomed in and didn't seem to impressed. Afterwards I realized when she said high iso, she said something that sounded like 800. I think she thought it was 800 ISO, lol!
