Who is this for?

The AstrHori 6.5mm f/2.0 APS-C Fisheye lens is ideal for photographers and videographers seeking a compact and durable lens for wide-angle shots. With a 192° angle of view and weather-sealing, it excels in capturing expansive landscapes, architecture, or creative fisheye effects, especially in outdoor and varied weather conditions.

Who is this NOT for?

This lens is not ideal for users needing versatility in focal length or low-light performance.
