Does ISO 1 even work? I thought all cameras have a lower limit for ISO well above 1. Have you checked if there is a difference between ISO 1, 5 and 10 for example?

Hej,
Yeah and which cam ?
Seems on mine ISO override has no effect at all. :/
(by the way, I'm not 100% sure of my testings, shouldn't we have some dedicated threads on the forums to discuss about new possibilities/camera limitations (like to the wiki table about it), one thread per cam ?)

I can get my TX-1 to display the ISO as 10-8000. That doesn't actually mean it is working as it says, but then again, I haven't actually tried to REALLY test it.
I'm still completely overwhelmed with all of the choices and too busy experimenting & playing!

-But I would like to test all of it so I could know.

generally the real iso50(marketed 80) is the smallest
with older cameras maybe you can get iso 30(50) too like with a610

I can't seem to find any info on how "digital" ISO actually works.

Well, after a long break I have come back to the forums! I am sorry I did not respond to this thread earlier. The ISO was nearer to 10, after I retested multiple times. I did achieve ISO's of 10 and lower, but, my A620 would crash and I could never get a picture, or it would revert to ISO 10 (although still reading ISO 1).

If only it wouldn't crash!!!
