+1, IS is not needed for me either, I use it for theatre in very low light. IS starts to become useful at close to 200mm.
If you´re looking for an excellent portrait lens, that´s a good lens and the deal seems to be fairly good. But it depends on what else you have and what you will use it for. I have it, it produces great results, but it is far from my most used lens. The 70-200 f2.8L IS II is more money, but also a lot more value.
I really do not miss IS on my 135L. I'm normally shooting at wide apertures, so fast shutter speeds are easy to achieve in all but the worst light. I think this is a terrific price, if I didn't already have one, I'd pull the trigger here.
The 135L is an awesome lens!
I totally agree. But if I didn´t have the 70-200 f2.8L IS II, I would get that first.
