I don't shoot much at high iso, so not a lot of great shots. This was shot with my *ist DL at 3200iso, with a sears 135mm macro lens. I forget the fstop, but it was probably wide open. Lighting conditions? I suggest drinking more beer before looking. I used Noiseware on it today.

K-5, ISO102400 sample...

I know it's early, but here is a first, for the sake of records:

K-5, ISOISO102400(+1 eV push in ACR), 1/800, f/10


and

Original Exposure:



TBH, I think that if the image was properly exposed, we might been able to squeeze just a little more out of it

I am not sure what this is trying to prove, have I missed something??? Aperture f/10 shutter 1/800 for a static image... why??? Surely the whole point of high ISO is to help shoot in situations where the light is poor or to get sharper images using higher shutter speed from fast action.

Yes in fact...

The RAW was snagged from a pre-production unit at Photokina.
I suspect the person in question had little time to do anything with respects to proper settings and conditions.

I also think the arperture was used to lower light levels and make the ISO selection possible.

Having said that, do keep in mind that this is nothing more than an early preview of what's to come with respect to a new breed of high ISO performances from Pentax. And most of all... something to have fun with

Pentax *istDs with Centon 50/1.8, shot at ISO1600 but pushed by 2 EV -> ISO6400. RAW, developed (and heavily modified, e.g. black is at 21) in Lightroom. No clue what the f-stop was.

John, thank you very much for this--now I am really interested in seeing more of the K5. BTW, Photome exif shows ISO @ 51,200. And, to be honest, I am not really sure what ISO you have written there.

The photo was taken at iso 51,200 and John took it in post processing and pushed another stop, so it is iso 102,400 equivalent. This photo was initially posted on the rumors/news section of the forum.

It's a little shocking that 51,200 ISO on K-5 is actually almost usable and looks as good as some cameras at 6400 ISO.

LOL. Josh, you could at least attempt to make your ISO test scene an interesting one.

Here is a shot I took today with my K10D at ISO 1600, no noise reduction applied.

Well I don't know about the noise, but that's one magnificent creature!
Great shot!

A shot of my father-in-law and niece around near a small bonfire about a week ago. I used my K-x and SMC Pentax-m f1.4 50mm lens, at f2.0 I believe.

Good picture, especially your father in law's face and the ways the shadows fall.

It is amazing what you can do with the old SMC lenses.

I was using my full manual 50 mm f2.0 from my 30 year old K1000 as part of my bag for about a year after i bought my K20D until I bought an autofocus Pentax FA-50 mm f1.4.
