I had both the 85 1.8 and the 135L.
The 135L was the first lens that immediately wow'd me. Fully open it's very sharp and has very little CA. I bought it together with the 35 1.4, 85 1.2 and 85 1.8.
I have sold 3 of the lenses again, which only leaves me with the 85 1.2.
Here why I sold them:
- 35 1.4: It's the only lens I've had trouble with. Sent it in a couple times, even 2 times with 2 bodies. Back-/Frontfocus was an issue. I could correct it via micro-adjustment on the fullframe, sent it in, came back, had to adjust even more which had the effect that it wouldn't be adjustable anymore on APS-H (out of range). Ultimately I decided to sell it off.
- 85 1.8: It's a good bang-for-your-buck lens with pretty good AF speed. But I mostly wanted to use the 85mm range for portraits, so it almost never made its way out of the bag, because the big brother 85 1.2 was there. I initially bought the 85 1.8 for concert/sport...for both of which I've used the 70-200 2.8 II alot more. That extra stop of light is not that big of an issue anylonger.
- 135L: Use of the lens got killed by the 70-200 2.8 II, yes I think it's just that good. 135L has a much slower AF speed aswell. With a bit of distance you can get (at 200mm, 2.
a pretty pleasing bokeh for portraits with the 70-200. If you however like the 135mm range alot and want to do portrait more than sports/concert/catwalk shows etc, then the 135L might just be the lens for you.
