Filter specialist NiSi has announced its first ever lens, the NiSi 4/15 – a 15mm f/4 ultra-wide optic for Canon RF, Nikon Z, Sony E and Fujifilm X mount.
Already many people's choice for the best ND filters and best polarizers, the NiSi is now turning its expertise in optics towards camera lenses with the NiSi 4/15. And while those looking for the best wide-angle lens are already spoiled for choice, the native RF and Z mounts make this a particularly compelling option for mirrorless users upgrading to Canon and Nikon's new systems.
The NiSi 4/15 features a 15mm focal length on full frame bodies, or an equivalent 22mm on APS-C cameras. Its optical formula features 12 elements in 10 groups, including one aspherical and two extra-low dispersion elements.
As you might expect it's a fully manual lens, with a dedicated focus and aperture ring. NiSi is keen to state how good the optic is for shooting sunstars and starbursts, thanks to its 10 straight diaphragm blades (with a minimum aperture of f/22).
It has a minimum focus distance of 0.2m, with a maximum magnification of 0.13x, with a 112° angle of view on full-frame cameras and 78° on APS-C systems. The lens is also fairly discreet at 75.6 x 80.5mm and weighting in at 470g.
It possesses a 72mm filter thread and supports 100mm filter holder systems – like those offered by the manufacturer itself, of course.
NiSi claims that the precise optical design retains high image definition across the frame, from the center to corners, with minimal distortion for photographing interiors and architectural shots. We're looking forward to giving this
The NiSi 4/15 is on sale for $539 / £419 (approximately AU$693).
