Now this is a problem for Pentax and other "traditional" dSLR manufacturers.

Pentax DA 21mm F3.2 Limted: distortion --1.97% (photozone)

Fuji XF 18mm F2: distortion --1.52% (photozone)

3mm wider, 1.5 stops faster, and a good bit less distortion. Similar price. Similar size. Similar quality.

Oh, sorry, the distortion of teh Fuji lens is actually --4.8%. Whoops, man, that's practically unusuable. Until you flip on the in-camera correction, which, in fact, never turns off. Hey - problem solved!

In-camera correction gives mirrorless manufacturers a huge advantage when designing "high end" lenses. This is like steroids and sports, only far from being banned, consumers are simply welcoming the extra performance.

The old guard who are forced (since the lenses must work decently on legacy cameras) to make the corrections optically (slower aperture, larger, more expensive lenses) in for an increasingly rough ride as more and more "amazing" lenses show up in mirrorless catalogs.
