I recently bought a subscription to Reid Reviews. He had an excellent article on wide angle lenses for Canons. The current crop of Canon wide angles are ok but not great – plus, very expensive. So, I tried his suggestion for saving money. Instead, I bought a Zeiss Jena Flektogon 20mm lens (multi-coated) off of EBay for $250. Then, I bought the Haoda M42 adapter with auto-focus confirm and crossed my fingers. The lens works great and the adapter works great.

Now, I just have to figure how to compose with a 20mm lens!
