I'm wondering if anyone has experienced this lens. I've had the chance, but skipped it for the 135L
If by "this" you mean the 100/2, I have no problems with it. However, I've never used it at f/2 for anything beyond test shots since I pretty much use it only for portraits. I've also never used the 135/2, but after looking through pretty much all of the sample thread, I don't see much difference in the renderings of the 135 and the 100. The 135 looks better in some cases, and simply ordinary in others...I won't be buying one until I absolutely need the working distance.
By comparison, I thought the 50/1.8 rendered things ok, the 50/1.4 wasn't much better, the Sigma was pretty good but still doesn't have "something", and the 50L is great and has that "something", at the cost of simply terrible bokeh in certain conditions.
