7Artisans has introduced a new, budget circular fisheye lens with a unique 225° field of view for APS-C cameras. This 7Artisans 4mm f/2.8 lens makes taking 360° panoramas easy, and could even be a 180° VR video solution. Let’s have a look at the specs!
Founded in 2015, 7Artisans has made a name for themselves with a range of cost-effective, manual lenses for mirrorless mounts. Though their lenses come with some compromises, their fresh take on design is a welcomed retreat from the norm and is, in some cases, unmatched.
This lens joins a tiny list of lenses that can create a circular fisheye perspective on a Micro Four Thirds or APS-C camera. Circular lenses are a very niche product, not a standard carry fisheye lens.

7Artisans 4mm f/2.8 circular fisheye for APS-C: overview
The 7Artisans 4mm f/2.8 lens’ 225° field of view can produce a 360° panoramic still in a minimum of 2 clicks. Whatsmore, this lens can also be used to shoot striking, ultra-wide video. The video can then be processed in post for use in 180° VR applications, or paired with a second camera to create 360° VR or 180° stereoscopic VR on a budget.
The Art & Science of Lenses

The 201g all-metal body is lightweight enough to allow the lens to take to the skies on an X5 DJI drone. The manufacturer refers to this as “God’s Perspective,” a visual experience that is certainly unique.

Competition and pricing
Although there are a wide variety of circular fisheye lenses for Full Frame sensors, very few are designed for APS-C. That doesn’t mean 7Artisans 4mm f/2.8 lens is in a league of its own. For example, both Meike and Venus Optics have had circular fisheye lenses on the market for some time now.

Meike’s 3.5mm f/2.8 circular fisheye lens is nearly identical to 7artisan’s 4mm f/2.8. It offers a similar 220° field of view and weighs only 190g. It is priced at $139; however, it is only available with an M43 mount.

Venus Optics Laowa 4mm f/2.8 provides a 210° angle of view, weighs 135g, and is available for EF-M, X, M43, Z, E, and Leica mounts. It is priced at $199.

The 7Artisans 4mm f/2.8 lens looks to be a terrific budget option for creating circular fisheye images. It is currently available to order on 7Articans’ site for $149.
