Canon T4i w/ 18-55mm and a 55-250mm lens...accessory question

The hoods you need:

For the 18-55: http://www.amazon.com/Fotodiox-Dedicated-Bayonet-18-55mm-Replaces/dp/B002K3Z3DO/ref=sr_1_2?s=electronics&ie=UTF8&qid=1360359364&sr=1-2&keywords=canon+ew-60

Related: Those rubber hoods are junk. They aren't custom-fitted to the lens, so they can potentially block the corners of the image; and they aren't rigid, so they don't provide any bump/drop protection for the lense.
