What a disappointing situation with the 17mm lens! Why?

I fully agree on that bit of 12/17 comparison.

I agree that the 12mm lens shows that Olympus can do better. The 17mm being less wide should have been equally good at just a bit lower price. But I guess sharpness isn't everything in judging the value of a lens. The 12mm and 17mm f/1.8 both get the same overall score of 19 on dxomark, with the 17mm showing less sharpness.

But especially in these lower focal lengths so much goes into engineering a lens design... who knows what makes one focal length just that bit easier to get right and another much more difficult. Lens design is a very complicated matter and to some extent it gets easier with longer focal lengths, once you exceed the lens elements to sensor plane distance by enough. For short focal lengths I wouldn't be able to tell which focal length is easiest to make, 12, 14, 17, 19, 20, 25... but after that it starts getting better.
