dear canon,

I don't care about ISO 6 million.

let me have ISO 25 or ISO 12.5 or even ISO 6.25
now THAT would be cool.

while you're at it, I want focus points way out in corners.

ISO 100 is base. You could darken the photo in post if you needed ISO 25 or lower. Focus points in the corners would be nice.

But you couldn't use a longer shutter speed without an ND filter.

Somehow the Powershot I have can be set to ISO80.

My 5D will do ISO 50 but you have to enable extended ISO to access it.

yea that's how 5d's and 1d's are.

but i want lower!! how hard can it be to make the sensor LESS sensitive?

mostly i want it for panning, but i'd like to be able to shoot at 1.2 in the middle of the day too. 3 or 4 stops of ND and the viewfinder gets kinda dark!

Agreed, I shoot on ISO 50 quite a lot (as much as I can!) Have always thought it would be cool to go lower though!

Yes, ISO50 is a "pull" ISO on DSLRs, and will cut a stop of dynamic range from the highlights, exactly the same as if you pulled it one stop in a raw converter.

If you really want ISO50 for high-quality low noise exposures, forget DSLRs altogether and get a Hasselblad instead, a $12k H4D40 will give you 40mp, ISO50, leaf shutter for virtually no vibrations, etc.

I acquired an expensive camera so I can hang out in forums, annoy wedding photographers during formals and look down on P&S users... all the while telling people it's the photographer, not the camera.

Also, a native ISO 25 sensor could potentially have two more stops of DR than a native ISO 100 sensor.

I want to use ISO 50 too, or even ISO 25! But only if it gives more DR.

On Canon's cameras it doesn't, so meh..

I totally agree with the OP, I have never used more than 1600 and only rarely use more than 400, but a 25 and 50 with superb DR would get daily use.

Instead of ISO 25 (or 6.25), I'd rather like to see a 3-stop ND filter built into the camera like the G-Series cameras. Essentially, we'd get the same results.
