I know it is a little annoying to point out 4x faster, but what I see is the hope that the achievements in lens design will lead to better designs in my native formats. It wasn't that long ago that we had an EF 50mm F/1. I suppose it was to expensive to produce as a practical matter. But we are seeing a lot of very fast lenses coming out for APS-C and FF. Not necessarily by Canon. But the price and performance are breaking new ground. You have to admire a lens design like this. Even if the actual result might be a 50mm F/2...or F/4? It doesn't diminish the cool design to me.
