Somewhere around the 1990's I read about a doping method for film
being pioneered by AGFA that would bring allow film ISO's to exceed
204,800 with acceptable results IIRC.

I freely admit that I don't think I am really understanding the
implications of ISO 12,800. It's like a person being 20 ft. tall.
My mind has trouble associating that number with that property. I
noticed that one high end Nikon had a max sensitivity of 102,400.
That's like trying to grasp an f0.1 aperture. It makes mathematical
sense in terms of EVs but I never thought I would see such a thing.

Here's another K-X example if you need low light capabilities.
Pretty much
a straight import into LR3 - at ISO 12,800. The noise isn't

One big difference for me was that with the K20 and earlier I
really had
to have good conditions (lighting, processing, etc) to make a high
ISO shot reasonable. For instance, when shooting weddings I could
take a couple of shots with the 50/1.4 lens close to wide open and no
flash, then process to remove ugly color cast and grain, etc. The
resulting image would possibly even need to be turned to B&W.
Basically, this meant that the shot was not the norm, but the
exception.
With the K-x, it is totally changed. Straight out of the camera, ISO
6400 is looking quite good - no extra work. So now I have shot
entire receptions with no flash and no heavy post processing. Even
more so, simple snaps of the family in situations where I would have
used a flash in the past, I no longer need to. Gathered around the
dinner table talking in the evening or playing a game or one of the
kids receiving an award at school, etc. The ability to shoot
consistently at high ISO (1600+) is a real game changer.
ISO 6400, 85mm Soft Focus lens, no post processing, shot right after
dinner:

I would never have thought to take that kind of shot in the past.
That is why I am saying to try the K-x and really see how different
you start shooting and thinking. When I got mine, it was only to
shoot a gymnastics sporting event - that covered the cost for me. It
turned out to be just the tip of the iceberg.
Here is a shot from a reception - fairly dim lighting - ISO 6400 -
pretty much no post processing:

With flash, the shot would not be the same. This is the kind of
thing I am talking about. Not really thinking about how you shoot
today, but really thinking outside of the box. For me, the K-x was
really a game changer in thought process and fun. Prior to that,
pretty much the old thought process all the way back into my film
days.

Time to change it up and see what this Brave New World is offering.
