K5iis versus K1 ISO range

Am I right in thinking that the minimum ISO 80 for the K5iis is inferior to the K1's ISO 100 on the basis of format differences? I ask this as I am contemplating which APS-C I should be selling (K5iis or K3).

I am leaning towards selling the K5iis as the K1 will more than adequately make up for the 'loss' of ISO 80. The K3 will be my main wildlife/ macro setup (focus peaking is another benefit over the K5iis).

The pixel pitch is roughly the same if you compare the two sensors. The newer chip in the K-1 offers better color depth and more dynamic range, though, so that should deliver superior pixel-level image quality and base ISO. The fact that you have more than twice the number of pixels then seals then deal

Two school of thought. One says each pixel on its own determines the performance based on pixel pitch and generation of sensor. The other school says total light on the sensor is most important. I think there is some truth to both.

As Adam pointed out the k-1 had nearly three same pixel pitch as the k5ii. The sensor is larger, and of a newer generation.

I guess the idea with the more pixel advantage is to display/print at any given resolution you can average more pixels to reduce noise...

thanks guys. while I really love my K5iis it would seem I am not 'losing' by selling it after an upgrade to K1 (with a K3 as backup).
