However, I found that it will has some strong light fall off when wide open. As a result,, I am interested in getting either 19mm/2.8 or 21mm/2.8 ASPH to replace my 21mm/f4. I just wonder How do they perform when they are wide open ? Also, which lens has better optical quality ? Any suggestion is greatly appreciated. Eddie
