It seems to me that Sekonic and Gossen both approached the challenge the same way, in the name of user friendliness. What's easier to do: 1) twist a knob or 2) remove one disk and replace it with another. The answer is obvious. If I were a product designer thinking about the end user, I would be tempted to go with the knob solution myself. But just think of the physics of the problem. Oblique lighting.....and a diffuser hiding in a well? Does that sound like a like the best solution possible? Maybe they've got it all figured out, they've done the physics, implemented the calculus, and I'm being too smart. I admit, this is speculation on my part as I've not done tests. That's why I'm posting this question, before I buy. Perhaps I should shut up.
