The lens features a large F1.8 aperture, allowing for excellent low-light performance and beautiful background blur (bokeh). You can adjust the aperture using the dedicated aperture ring on the lens. The aperture ring offers both click-stop adjustment for precise control and a click-less (OFF) mode for silent operation during video recording.

4.3 Optical Performance
This ultra-wide-angle lens delivers outstanding image quality with excellent center-to-edge resolution. It incorporates specialized optical elements, including aspherical lenses and low-dispersion glass lenses, to effectively suppress various aberrations and control flare and ghosting, even when shooting against bright light sources. This ensures clear and sharp images, particularly beneficial for astrophotography where point light sources remain distinct without flare.
