Why wont my K-x go below 400 ISO?

slackercruster · 05-22-2012, 07:53 AM

I got 2 K-x's I bought used. One goes to ISO 100, the other one wont go below 400. Did they have different model K-x's?

Check to make sure "Highlight Correct" & "Shadow Correction" are both disabled under the "D-Range" menu option.

Congrats on acquiring 2 copies of the Best DSLR Ever!

Only one K-X
You need to program the ISO range in the navigation menu

Yep, that fixed it some. It will go to 200 ISO, but not lower. The one K-x just that goes to 100 shows just the ISO setting on the screen. The other body that goes to 200 shows 2 boxes. ISO on the bottom 200 > and another box above it that says ISO AUTO and show 200 - 800 in the box.

A related question. The shadow correction has 3 steps. Should I use the middle step or leave the 3 steps off altogether? (I tried it off and ISO was not affected.)

The K-x is a beautiful little gem. It was my highest body in my collection. But now that Pentax is coming out with some 16mp cams that run on 4 AA I may add to the stable.

I looked in the menu but could not find it. What section is it in?

Go to C menu, number 1, then 3 Expanded Sensitivity, Using the four way controller, expand the options, choose number two(2), okay out, and hit the menu button again.

THe native ISO of the K-X is 200, that why you need to go to the extended mode

Because sometimes, I need to be able to shoot at ISO100. Bright sun light and accompanied flash unit being one.

heh,

I was having the same issue and wondered what setting I had used to cause it to act that way.

Now I know. :-)
