Nisi 9mm f/2.8 Review by Christopher Frost
The Nisi 9mm f/2.8 lens for Fujifilm X mount has just been announced. You can see samples and specs in our dediacted launch article.
Now Christopher Frost shared his review about this lens (mounted on a Sony full frame camera).
Here is the summary of his video:
- smooth focus and aperture ring
- focus ring turns a little heavily and very precise for manual focusing
- almost no focus breathing
- 67mm filter size is nice and unusual for such a wide angle lens. Use a slim filter with this lens to avoid to occur in vignetting
- metal lens hood
- lovely build quality
- image quality
- at f/2.8: excellent sharpness and contrast in the center and still quite some good detail in the corners. The very edges are soft
- at f/4 corners quickly improve to become very impressive
- at f/16 comes a bit of softness due to diffraction
- at f/2.8 distortion isn’t too high with just moderate barrel distortion
- at f/2.8 huge vignetting in the corners and they begin to brighten up at f/4
- 20 cm minimum focus distance and remains sharp at close distance
- average amount of flaring although it is fairly transparent hence it should rarely cause any problems
- coma smearing is absolutely minimal even at f/2.8 and what eventually is there is gone at f/4
- some sunstar effect is visible even at f/2.8 and they become quickly nice and strong at f/4 and they get even better at f/8 and f/11
- bokeh perhaps just a little nervous, but nothing too distracting
- overall he is pretty impressed by how well this little lens performs
