NiSi is best known for making ND and ND grad filters, but the brand has widened its horizons by releasing a brand new lens that will appeal to landscape and architecture photographers. The NiSi 15mm f/4 ASPH is a manual focus optic that is available for mirrorless cameras using Canon’s RF mount, Nikon’s Z mount Sony E and Fuji X mount.
Featuring a full metal barrel design, the lens offers a ‘12 elements in 10 groups’ construction and, as you’d expect from a brand that makes filters, features top quality glass. In fact, NiSi explains that the lens features one aspherical element and two very low dispersion elements to ensure a high level of sharpness. The internals are backed up by an anti-reflective treatment that will reduce flares and internal reflections.
With a 15mm focal length, the NiSi lens will be well suited to landscape photography and the 112 ° field of view will help make the most of foreground interest in the frame. Although designed for use with full-frame cameras such as the Canon R5 or Sony a7R IV, the lens can also be used with APS-C crop sensor mirrorless cameras from Canon, Sony, Nikon and of course Fuji, such as the X-T4, where the effective focal length switches up to 22mm.
A good option for those travelling and seeking lightweight equipment, the NiSi 15mm tips the scales at just 470g and measures only 75x80mm. Impressively, the lens also features a closest focusing distance of just 20cm, enabling photographers to fill the frame with a subject despite the ultra-wide focal length.
The 10-bladed diaphragm should create some impressive bokeh and attract starburst effects when capturing light sources at a small aperture such as f/16. Along with a wide focus ring to help users focus up on their subject, the lens includes an aperture adjustment ring, making the lens a great choice for video shooters, too.
The lens ships with a lens hood to help protect the front element from the rays of the sun and features a 72mm filter thread, enabling users to add filters to control the exposure in the frame. Additionally, one of the most impressive things about NiSi’s 15mm f/4 is the price, with the lens available for £430.
