I purchased a used Sigma 50-500mm f/4.0 to f/6.3 Super Telephoto lens. The official designation is as follows "50-500mm F4-6.3 EX DG/HSM. I really wanted a looooong range lens for events, like the Strathmore Stampede and air show I wanted to attend. Best way to put it, big and heavy! But here is something important here, the range. In the picture I used two lenses. the Sigma 50-500mm and Sigma 10-20mm to show off the entire range that I now have. I included the 200mm to show the maximum range of the Nikon 18-200VR lens and the 50mm is there to show the widest the 50-500mm can get.

Enjoy!
