High Iso or Low Iso?

[John King]

Hi John, that’s good to hear. At least it helps a bit in the visual appearance of the highlight roll off but RAW headroom stays the same.Have a look at photonstophotos’ PDR graph where it flattens in the extended low range.

Are you sure you are looking at the MkII ?

The MkI DR is lower in extended low at Bill's site, but the PDR for the MkII remains much the same. This appears to have changed since I last looked at it about 12 months ago. Or I am going dippier than I thought I was? Always a strong possibility!

Got to post this. My tablet had to be rebooted because it spat the dummy!
