why would you need to change the iso besides the normal way ?
normally i shoot in 100, if i need to go up i go for 200 or 800. these are the three isos i ever used...
i still don't get why would one need 125 iso (for example) ... what will be different from the 100 iso ?
even more ... i dont see the point to have the nice DP button assigned to iso changing...

I see the idea, I guess I got confused, because I was thinking that ppl are using this function only between 100-200 ISO values, because I mostly use 100,200 and 400. But you are right, it has a good use when you need ISO between 400-800 or 800-1600
Though I don't think ISO 1600 is usable, neither 3200 because of the noise. Perhaps only in rare cases like JoeNeptune mentioned. Anyways let's leave this off-topic alone.
Thanks for clarification.
(nice photos there, congrats.)
I'm an actual photographer who takes portraits and does night club photography as a job, and i personally believe my skill and knowledge is greater than the average photographer.
Why would you need to use any other ISO other than ISO100?
Why not?
It's been said that the ISO's in between the pre available ISO values are 1/3 stop difference.
It's the same as adjusting your shutter speed to allow 1/3 more light in than your current settings (whatever they might be).
Say I want a fast shutter speed of 1/100, I don't want lower. My aperture is maxed out wide open already. The only thing to allow 1/3 or more light in is to increase the ISO by 1/3 or more.
Which is why one would want the ISO values in between.
There is no why someone would want to use ISO 125. They do because the photographer behind the camera chooses to, so they do.

ISO1600 is noisy?
You need to learn to embrace the noise.
You're more than welcome to take a blurry image due to a slow shutter speed @ ISO1600, while I get a clearer one with ISO3200.
As right now, you're saying your skill is being limited by the noise of the camera.
The more you start shooting and looking at the image instead of the technicals, the more you improve.
I use ISO3200, F/2.8, and 1/4 in the clubs to take an ambient shot. It works so well.
I cannot get the same results with ISO1600.
Here's an example:

Yeah? ISO1600, would require slower shutter speed, which gives allows camera shake to be more visable in the final image.
I'm just saying, there's a time and place for the 1/3 stop ISO's, and noise is nothing but a bunch of coloured dots on the image.
Don't let it get in the way of your creativity.
