M10M: What is the "native" ISO?

Hi all,

I hope I'm asking the right question.

I know the lowest ISO for the M10M is 160, but what is the "native" ISO for the M10M where the absolute sweet spot is for image quality?

Is it 160?  I thought I'd read somewhere it was 200?

Anyone?

 

Thank you in advance,

cayenne

If the native ISO of the M10 is around 160, which has been deduced here on LUF if I’m not mistaken, then the M10M should rather be around 320 then lower.

There is already a very recent thread here discussing the native/base ISO.

I read through all that...didn't quite see an agreed upon answer there tho...

Ok, will keep looking around. Please chime in if there is more info ya'll come across.

Can you expand upon your claim please?

Why do you feel this would be the case?

 

Thank you in advance,

You're assuming the same sensor, which is not true.

I think the answer can be deducted from the following facts:

- highest PDR is measured at ISO 160

- Lowest ISO value used by Auto ISO is 160. No camera uses pulled ISO values in Auto-ISO mode.

Is that so? I thought it was the M10 sensor without the Bayer filter, as in MM1 and M246.  It’s not the M10R sensor, is it?

The M10 Monochrom and M10-R sensors are derived from the S3 sensor architecture, with the former lacking the Bayer array.  Both are 40.89 MP, unlike 24MP in the M10.

Have a look at Reid Reviews - I seem to recall the view there was that it was ISO400. But I could be wrong....
