Worth Knowing
−Manual focus only - requires deliberate composition and hand-on operation
−Non-threaded bulging front element prevents filter use and requires careful handling
−Extreme distortion and field of view make it a specialized tool, not universally applicable
−Corner softness at maximum aperture, though improves when stopped down to f/4-f/5.6
