Discovered: All-encompassing, round fisheye lens for full-frame cameras, offering versatile mounting possibilities
New AstrHori 6mm f/2.8 Circular Fisheye Lens for Full-Frame Cameras
AstrHori is set to release a new circular fisheye lens, the 6mm f/2.8, designed for full-frame cameras. This lens, which boasts a 192-degree field of view, is expected to join the recently released 6.5mm F2 circular fisheye lens for APS-C cameras.
Key Features
The 6mm f/2.8 lens features a compact body and a typically bulbous front element, making it a suitable addition to any photographer's kit. It is a manual focus lens, with no electronic contacts, which is common in AstrHori's design.
The lens's ultra-short focal length is expected to provide a very large depth of field, making manual focusing relatively easy. This, combined with its wide field of view, should make it an attractive option for photographers seeking an ultra-wide, budget-friendly fisheye option for full-frame cameras.
Availability and Price
As of early August 2025, hands-on images of the lens have surfaced, indicating that it is nearly ready for release. However, no official release date has been announced yet. Based on AstrHori’s pricing for similar lenses, such as the recent 6.5mm f/2 circular fisheye for APS-C cameras priced at $129, this full-frame 6mm f/2.8 lens is expected to be in a similar affordable price range, likely around $129.
Technical Details
The lens's optical formula, aperture blade count, and additional features like coatings have not been officially published yet. However, it is known that the lens is designed for full-frame cameras and is expected to be compatible with Sony E, Canon RF, Nikon Z, and L-mount cameras.
Testing and Recommendations
Ben Andrews, the Imaging Labs manager, is responsible for testing the new lens on Digital Camera World and Future's photography portfolio. With years of experience in trialing and testing photography equipment, Ben Andrews is a reliable source for technical insight and recommendations for the best camera buys.
