A MUST BUY.,
Verified Purchase(What is this?)
This review is from: Canon EW-73B Lens Hood For 17-85mm f/4-5.6 IS EF-S and 18-135mm f/3.5-5.6 IS Lenses (Camera)
When I bought my Canon 550 DSLR with the 18-135mm lens I thought I'd spent enough money on official Canon products and so bought a cheap screw in hood for pennies thinking one bit of plastic was much the same as another.
How wrong I was. The cheaper hoods cause a huge amount of vignetting from 18-24mm causing me to loose some shots and effectively wiping out my wide angle capability in sunny conditions. So I bit the bullet and bought this official Canon product. It is amazing. Cuts flare, NO vignetting at wide angle and makes the camera look the part too. Do not dither, if you have a Canon EF-S 17-85mm or EF-S 18-135mm lens then buy this hood.
