iso expanded for k-x?

LosHollyBeach · 03-03-2010, 04:47 PM

so i recently bought my wonderful k-x about three weeks ago and i was looking at the reviews in the forums and i saw that the iso have been expanded

ISO range (expanded) 200 - 6400 (100 - 12800)

my question is to get the new iso range do you have to have a newer model of the k-x or its a update type thing?

because i will mighty upset if i just bought this camera and they are making newer models of the same camera have different features.

Why would Pentax disable this by default? It seems to me to be one of the defining features of this camera, and I would think should be enabled by default at the factory?

6400 is your FRIEND!

And disable that annoying automatic pop-up flash forever.

ISOs 200-6400 are "native" ISOs which are produced by turning up the gain on the sensor. ISO 100 and ISO 12800 are produced by manipulating data that the sensor actually captured at 200 and 6400, respectively.

Ok, makes sense. I guess I'm still not clear though on why Pentax doesn't have this turned out to at least allow access to the other ISO's (even if it's software manipulation).

The shooter could still stick to the 200-6400 range.

From what I know, (which isn't much, but correct me if I'm wrong), many camera manufacturers, not just Pentax, have the extremities of ISO (high and low) locked, as someone said, they are likely to be very noisy. The camera is advertised with the 200-6400, and the 100-12800 is an extended range, that most basic users won't like to use anyway.
Many other cameras do this.
