That gave me a good chuckle. Imagine what some of these guys have to do when they’re pixel-peeping those gigapixel images that Google and others put together. I don’t have the S, but having the MM and X Vario and seeing the detail as well as the integrity from edge to edge, I wouldn’t second-guess the S or any of the lenses. I can’t imagine anyone accepting a so-so lens at the prices they demand anyway, and if someone did think their lens wasn’t reasonably sharp wide open at all points, the Leica dealer would fall all over themself inspecting it to make sure.
Edit: I pixel-peeped the big picture – plenty of detail in the stadium, but looking at the foliage *outside* of the stadium at the upper right, detail in the foliage at that distance is still visible. Pretty amazing.
