This is excellent commentary here. I have used both the 105/2.5 and 135/3.5 extensively. "Stellar" is the prefect way to describe them. I was shocked when I noted excellent wide open performance in the 135/3.5. The 105/2.5 is nice wide open, too, but the 135/3.5 seems a "hair" better. Indeed, the modest maximum aperture in these lenses, as in others, really helps. These lens designs just have very few compromises, and the proof is in the performance.
