CanonLenses

The CanonLenses app is a guide to Canon's current lineup of EF and EF-S Mount lenses used by both Canon's digital and film SLR cameras.

You can view all the lenses at once or you can view lenses in a selected category. You have the ability to sort by aperture, minimum focal length and ESP (Estimated Retail Price).

Each lens has a detail page which provides links to the Canon web page detailing the lens, reviews of the lens from third parties (if available - brand new lenses might not have reviews yet) and information on where to rent the lens in the US (if available).
