Product Rating: 4 star(s) Field review of Canon 8806A002

, Feb. 1, 2005
Comments:
The lense is very fast focusing and quick recovery from changes. However, under low light conditions with or without the supplied hood there is a definate shadow present at the bottom of the image. I use this lens for landscape and some portrait work wit
