What I like about the K-1 (both versions) is the attention to detail.
For example, I can finally read the current focal length of zoom lenses on the rear display.
I've waited for ages for this feature and now I can put the mm tile wherever works for me.
The light button is excellent but even better is that I can define what it does.
I have only started with the first of five presets and they are all selectable via hardware dial.
I can rename it to "Action" which is way better than something like "User Mode 1".
The camera tries really hard not to get in your way while you are busy taking photos.
