Re: You do not need the concept of ISO here

Exactly, ISO here is a red herring. However sensor is covered with the filters and microlenses, and if you take them off, Canon 1D MkIII has sensor sensitivity very close to Nikon D3 retaining larger well capacity and higher pixel pitch, while one of the biggest differences between SONY and Nikon versions of the same sensor pack are CFA and AA layers.

Canon 1D MkIII achieving ISO 100 (actually also depends on how one measures it, I would say it is actually ISO 75 against ISO 135 in D3) is in part the result of higher well capacity compared to Nikon D3. The other part of the equation are different white balance pre-conditioning factors between the two cameras.

One of the options Nikon have with SONY 24mp sensor is to perform same AA/CFA rework they did with other sensors, and then it would perform better.
