spent $49 on a new hood for my beloved lens. sold e one which came wif my lens last week at $40. think $9 more for sthg useful is reasonable.

wats e problem wif e original hood? well, e 17-40 was designed for film/ff dslr. 17mm is very wide (104deg angle of view). so e hood needs to b wide n shallow. however when used on a 20d, e focal length is multiplied by 1.6 makin it 27mm (75deg angle of view). so e hood becomes useless. i need sthg deeper.

e new hood is meant for e 17-55 which is a new lens meant for aps-c dslrs. fortunately enuf, e widest angle of view n e filter size r e same as mine. yay.

wanted to try to gaffer up my new hood to protect it from scratches. got some gaffer tape from patrick. not an easy thing to do. spent like 1hour. cos e tape is made from cloth so it's not easy to cut. but den pat said that i need to replace e gaffer every 6months to prevent it from leavin adhesive residue. -_-'" dun think i'm gonna do it again.

e end result is quite satisfyin
