AstrHori 6.5mm F2.0 6.5mm f/2 Fisheye 7mm
This manual fisheye lens delivers a distinctive circular image with strong distortion that many users love for creative shots like skateboarding videos and travel photos. Build quality is praised as solid for the price, but compatibility issues on Canon mirrorless and full-frame cameras are a notable drawback.

- Manual focus only, tricky to use
