I didn't see the original post but even if noise was effectively the same at ISO 100 and 200 having the lower
speed would allow more DOF control in bright light without using ND filters, (which can be a PITA).

The resolution is exactly the same (2008 x 3008) at any ISO setting. I suspect you mean noise level?



I keep hoping that a future "Daddy" D will have a min
range of 100. Do I care?



I thought I would but have found that it doesn't make much difference to me most of the time. The noise level is more than low enough for me at ISO 200 that I don't need anything lower as far as image quality is concerned. I use ND filters when I need longer shutter speeds. I *would* like lower (and higher) ISO capability when I'm working with a fixed aperture/shutter-speed combination and fiddling with exposure by changing ISO.
