Worth Knowing
−Manual focus only—challenging to achieve critical focus at maximum aperture without viewfinder magnification
−Noticeable chromatic aberration wide open, especially under high-contrast conditions
−Soft center sharpness at f/1.8; sharpness improves gradually stopping down to f/4 for center, f/8 for corners
−Control ring's extreme aberration settings may sacrifice in-focus sharpness of main subject for creative effect
