Worth Knowing
−Manual focus only with no autofocus capability
−Fixed f/5.6 maximum aperture limits low-light performance, requires tripod for night photography
−No front filter threads due to protruding fisheye element design
−Notable barrel distortion and potential chromatic aberration typical of fisheye lenses
−Focus ring can develop play; ring may loosen over time requiring manual adjustment
