Description — NiSi 15mm f/4 Sunstar
The NiSi 15mm f/4 Sunstar is a manual focus, wide-angle prime lens designed for full-frame mirrorless camera systems. With a fixed 15mm focal length and a maximum aperture of f/4, it delivers a broad field of view suited to landscapes, interiors, and environmental scenes. The lens is offered in four mount configurations — Sony E, Canon RF, Nikon Z, and Fujifilm X — giving photographers flexibility to pair it with their existing mirrorless body without adapters.
Weighing in at 470g and featuring a 72mm filter thread, it strikes a practical balance between portability and filter usability. Since the lens is rated for full-frame coverage, it is equally at home on APS-C bodies in mounts like Fujifilm X. Focus is entirely manual, with no autofocus or image stabilization on offer, placing creative control squarely in the photographer's hands.
This is a lens for shooters who value optical simplicity and deliberate technique over automation.

Frequently Asked Questions — NiSi 15mm f/4 Sunstar
Which camera mounts is the NiSi 15mm f/4 Sunstar available in?+
The lens is available in four mounts: Sony E, Canon RF, Nikon Z, and Fujifilm X. This covers the major full-frame and APS-C mirrorless platforms, so you can choose the version that matches your specific camera system.
Does the NiSi 15mm f/4 Sunstar have autofocus?+
No, the NiSi 15mm f/4 Sunstar is a fully manual focus lens. There is no autofocus mechanism, so all focusing must be done by hand. This makes it best suited for deliberate shooting styles such as landscape, architecture, or tripod-based work.
Will this lens work on an APS-C mirrorless camera?+
The lens is rated for a full-frame image circle, so it will cover APS-C sensors without vignetting. The Fujifilm X mount version, for example, is compatible with Fujifilm's APS-C mirrorless cameras. Keep in mind that the effective field of view on an APS-C body will differ from what you'd get on a full-frame camera.
What filter size does the NiSi 15mm f/4 Sunstar use?+
The lens uses a 72mm filter thread, which is a common size that makes it straightforward to use with NiSi's own filter ecosystem as well as third-party screw-in filters. This is particularly useful for landscape photographers who frequently use ND or polarizing filters.
Does the NiSi 15mm f/4 Sunstar have image stabilization?+
No, there is no optical image stabilization built into this lens. Photographers who need stabilization at 15mm will need to rely on in-body image stabilization if their camera body supports it, or use a tripod for longer exposures.
