Like any lens, the OOF image of the 35mm/1.4 ZM is highly variable with aperture, obviously, but also focus distance, and what kind of subject is OOF. So far I don't think I dislike any photo that I shot with this lens due to its bokeh. It's certainly smoother than any of the current M-mount 35mm lenses except perhaps the Leica Summarit 35mm/2.5, though I don't have that lens to compare anymore.
