Canon Lens Shootout!

Posted on: July 31st, 2010 0

Canon 18-55mm vs Tamron 17-50mm

I wanted a faster lens, so I just bought a brand new Tamron 17-50mm zoom lens to replace the lens that came with my old Canon Rebel XT. When I replaced it with a Canon 40D, I sold the XT body but kept the lens. The Canon kit lens’ maximum aperture is f/3.5, but is variable to f/5.6 at a 55mm focal length. The Tamron has a fixed max ap (stays the same across all focal lengths) of f/2.8. However, I was curious as to what the difference in optical quality was, if any. So I performed my own “Shoot Out!”
