1.Core optical performance – ultimate wide-angle field of view
· 225° Circular Fisheye View: With an ultra-wide field of view of approximately 225°  this is one of the widest-angle lenses available on the market. When shooting, a complete circular image appears in the center of the frame, with black borders around it, creating a unique “fisheye planet” effect that is highly visually impactful.
· F2.8 Bright Large Aperture: This is a relatively large aperture design for a fisheye lens, ensuring sufficient light intake in low-light conditions (such as night scenes and starry skies), enhancing shooting flexibility.
· Excellent Lens Structure: It features an optical structure of 8 groups and 10 elements, with multi-layer coating on the lenses, effectively reducing glare and ghosting, and improving color reproduction and image clarity.
· Special Purpose Design: The lens design effectively reduces internal reflections (such as glare and ghosting), maintaining pure image quality. 1. Core Optical Performance – Ultimate Wide-Angle Vision

2. Workmanship and Portability – Lightweight and Durable
· Ultra-lightweight design: The lens weighs only approximately 201 grams, is compact in size, measuring around 60mm x 54mm – 57mm, and can be easily placed in a pocket, making it suitable for carrying around.
· Solid metal body: Made of all-metal material for the lens body and metal snap, it offers a solid feel and excellent durability, capable of adapting to various shooting environments.
· Friendly for drones and VR: With its ultra-lightweight and compact size, it is highly suitable for installation on drones for aerial photography, or for professional applications such as VR imaging and virtual guided tours.

3. Control and Compatibility – A Purely Manual Creative Tool
· Pure manual focusing design: The manual focusing design enables photographers to precisely control the focus. It should be noted that since it is a pure manual lens, before use, the “no lens release shutter” function must be enabled in the camera menu.
· Ultra-short closest focusing distance: The closest focusing distance is approximately 0.085 meters (8.5 cm), allowing for close-up shots of the subject, creating a highly exaggerated perspective effect.
· Aperture range: The aperture range is F2.8 – F16, providing ample creative adjustment space.
· Wide range of mount compatibility: It supports various mainstream micro four-thirds mount versions such as Sony E, Fujifilm X, Nikon Z, Canon EF-M, and M4/3, with extremely strong adaptability.
· Usage tips: If using this lens on a full-frame camera, the film format needs to be switched to APS-C mode in the menu to avoid vignetting.

4. Creative Selling Points and Cost-effectiveness

· 360° panoramic stitching tool: With a 225° ultra-wide viewing angle, only a few photos are needed to easily stitch together a complete 360° spherical panoramic image, eliminating the cost of expensive panoramic tripods.
· Unique artistic expression: The strong distortion effect provides unlimited possibilities for creative photography, and can be used to capture “mini planet” effects, exaggerated portraits, architectural domes, skiing/skateboarding and other extreme sports images.
· Affordable “toy”: At a price of a hundred yuan, it offers a highly playable creative shooting tool, which has been rated by users as “uncompromising shooting logic” and “a must-have non-mainstream weapon”.
· Target audience: It is very suitable for creative photographers, panoramic enthusiasts, VR content creators, drone players, and any photography enthusiasts who want to try the “fish-eye perspective”.
