Historically speaking, Canon has provided a lens hood and case (or carrying pouch) with the purchase of L-series lenses. However, Canon has generally not included the accessories with non L-series lenses.
However, according to B&H's "What's In the Box," a lens hood and case will be included with the new Canon EF 35mm f/2 IS USM Lens. The included accessories are also confirmed on Adorama's site.
With the announcement of center-pinch lens caps from Canon, that may be two items we can cross off Bryan's "What I Want From Canon for Christmas” list from 2010!
Preorder the Canon EF 35mm f/2 IS USM Lens at B&H, Adorama, and Amazon.
