not so good. firstly, the pictures somehow always come out OOF. i focus on background, put the IR filter, shoot, and for some reasons, the subjects at the side is focused rather than the center. worse still, the side subjects are only 1m away from me when my background is like almost at infinity(20m). *center spot focusing used*
secondly, i see a purple streak (very very very faint) across the center horizontal. but it is almost invisible when i turn it to black and white.
wanted to post some pics, but photobucket.com cannot enter. anyway, those pics not that nice. just testing out the IR effect.
