I often found the 1m MFD to be a pain, and the focus shift is horrible as mentioned. Those are the reasons I sold mine.
The lens is kind of big and heavy, however this contributes to the excellent ergonomics; I've found no other lens that's nicer to focus.
The front element can be kind of intimidating to the subject - it's like staring into a black hole, it sucks in all light from the surroundings.
Sharpness at 1.1 will often be limited by your slow shutter speed, at 5.6 it gets pretty sharp and the bokeh is excellent, making it good for most types of photography. Barrel distortion might limit it's use for architecture.
