Thanks for sharing, I was always curious if the L and H modes get used that much.

I gathered as much regarding lower IQ at ISO 50 from the articles I've read and posted above, since essentially the camera sensor will always receive the same amount of light, and changing ISO value results in amplifying the analog data prior to readout (or maybe during, I suppose), so in the case of L mode, you're essentially overexposed by default and can risk blowing highlights, causing the de-amplified signal conversion to potentially be lacking in highlight detail (and therefore reduced DR) even though it is a lower ISO.

Man, that was a long sentence

Makes perfect sense, once I got over the fact that ISO on film and digital work in completely different ways.
