Why images is sharp in the center but soft on the edge?

Anamorphic lenses are responsible for the “cinematic” look, featuring the characteristic of crisp and clear center images with soft and blurred outer edges, which can lend a painterly, artistic quality to your footage.

Why can't I take pictures with this anamorphic lens? Any particular setting to do in the camera menu?

Please enable "Release Shutter without lens" in your camera setting. Because the manual focus lens does not communicate with the camera.

Why images have distortion using anamorphic lenses?

All anamorphic lens exhibits distortion, either pincushion or barrel distortion, which is a common characteristic among this certain optics. For those well-versed in post-production, addressing this slight distortion is a straightforward task.

Why the lens flares are excessive or insufficient?

The intensity of lens flares is deeply affected by the filming operation and light source. It can be controlled by filmmakers to an expected outcome.
