This is the sharpest, punchiest (high contrast) fisheye lens I’ve tried, and is definitely fun to use. I wasn’t expecting a whole lot considering it’s a zoom, and an old design, but I did really enjoy using it. It is remarkably consistent across the zoom range and focal ratios. I don’t see any reason to stop down as it’s just as sharp at f/4 as it is at f/5.6. The downside to that consistency is the coma and chromatic abberation are also consistent and don’t really improve by stopping down the aperture. If this lens weren’t so expensive, I’d be more likely to recommend it.
