Seems from the comments there are some "issues" about the article. I came away like I did when I saw it last discussed on the UHH, that it may vary widely depending on your make and model camera. Say looking at say the low end of ISO. For my Pentax K-5 (original version), the standard manufacturer suggested ISO is 200. Yet the Native range goes down to 100, and when set to Extended, 80. There is more variation in settings at the high end, but the oddness of the low end makes me wonder enough. There are likely differences between cameras as to both technical and marketing features to really make generalized statements across products as to "ranges" of ISO's to be meaningless.

I thought it was a good general explanation. I don't think any article could specifically cover every and all camera makes and models. Maybe you could contact Pentax for the answers you need.

Actually I did not have an actual question, just used my camera as an example of how they can vary. I know what I need about my camera's ISO. You mean the OP was asking about Pentax and not Nikon or Canon in the referenced article? I can't believe that! :twisted: :thumbup:

I think a regular feature of these types of articles is that everyone will try to tear it apart afterwards.
Most of what I saw was an argument about how ISO 50 is accomplished.

There was one statement that caught my eye--someone said that 1/3 ISO stops even in the native range were "digital pushes"
