The reason why you choose a fisheye lens for 360 degree panoramic shooting is mainly because it has a larger visual impact on taking a single photo, thereby reducing the number of photos that need to be spliced together in 360 degree panoramic photos. 2F2.8 Large Aperture: Wide angle and large aperture are major advantages for capturing landscape themes. Due to starry sky photography often shooting in dark environments, the larger the aperture, the greater the advantage of the lens. In the same lighting environment, lower ISO can be used for shooting to achieve better image quality. 3Fisheye Lens Are Also Ultra Wide Angle Lenses: During post processing, LR or PS software can be used to correct distortion through configuration files and post correction, resulting in a wider picture than ultra wide angle. 4Wide Compatibility and 8 Dazzling Needles: : Compatible for R, RP, R5 and other models.
