I have it and it gets the least amount of use of my lineup but it is also my favorite lens. For me, I have to use it on a tripod, no handheld mount but the image is fantastic for close-ups, portraits, and dramatic bokeh.
Have you looked at the Rokinon 85mm 1.4? I got to play with it a few weekends ago and found it quite nice to work with and the imagery is amazing. I think you'd be very pleased with it. Plus it's around $100 cheaper than the Canon.
