A great tool for learning about lenses

The Tamron Focal Length Comparison Tool simulates the effect of changes in focal length, allowing photographers to preview the look of different lenses before purchase.

What makes Tamron's comparison tool particularly useful is the ability to toggle between full frame 35mm sized cameras, such as the Canon 5D Mark II, and the more common digital sized cameras, such as the Canon Rebel series.

Tamron's tool allows viewers to look at 3 different scenes and review images taken from one spot with lenses ranging from a very wide angle 14mm to a super telephoto 500mm.
