Do you like your 85mm f/1.4 Lens (on any dslr body)?

After using the Nikon 85 mm f/1.4 lens on the D7000, I am convince that these lens are very tricky and you have to be careful when using it.

Alright... To be fair, the dog would not sit still and since I couldn't stand against a wall or use a tripod, it contribute to the blurriness of these images.  However, there were time when I push really had to keep a steady hand, and still at 100% crop, the eyes were not tack-sharp at all.  Here are some of the images I took with the Nikon 85 f/1.4 ($ 1450).  Some of these images could only be used as a thumbnail on a website.  Some of the images were awesome but you have to be very still (and the subject cannot move).

Note: All images were edited in Lightroom.  Maybe the next time, I will post SOOC images.

Here are some images I took with the Nikon 85mm f/1.8 which is way less than half of the price of the f/1.4 (lens above).

It was a bit of a challenge to get some of these exposed correctly since the lighting in the gym was horrible.

How do you use your 85mm f/1.4 lens?  How do you setup for a portrait shots on a go? Do you carry a tripod or do you use the "belly photography" technique?

Please share your experience.
