I just bought a Elan II E second hand and a 420 EX new and got the first pictures. The 1/3 upper part of the pictures are dimmer (slight darker) than rest of the picture. That 1/3 upper part seems slight underexposed...I don't know.
So, there is a problem with wrong angle bouncing flash, or one of two curtains don't work properly? I mention that I put Sto-Fen on the flash.
Thank you.
