TTArtisan Master Optics 21mm Camera Lens Full Width Manual Focus Lens Sony Camera A7 A7R A7S A9 For A7C F1.5 A7(A7M2) A7(A7M3) A7R(A7RM2)

Wide-angle and large aperture coexist: The large aperture of F1.5 and wide-angle focal length of 21mm allow you to display sufficient information even in large scenes, while also creating a space with a three-dimensional effect. Wide-angle lenses produce starbursts more easily than medium-telephoto lenses, which are dazzling at small apertures and attractive at large apertures. Metal Focus Wrench: To bring back the joy of photography, I'm used to using a focus wrench, like it's home on my left index finger. Support macular double shadow focusing and enjoy the fun of rangefinder camera. Stepped aperture with finger grip: Smooth damping feel, precise control of aperture size brings you a more satisfying photographic experience. Multi-layer optical coating: Reduces reflections on the lens surface, improves anti-glare ability and reduces the possibility of ghost flare. Superior Resolution: After adding the macro adapter ring, you can change the macro lens in seconds and instantly open the macro door for stable high-resolution image quality and enlarged images that are not affected by dispersion.
