  • Tamron 150-600mm It's the best of the three you mention.  Avoid the Sigma, it's very soft at 500mm. If you were only going to be birding the 400mm f5.6L might be  a good choice but, the zoom is ...
  • Tamron 150-600mm would work great for your purposes.  It is as good as the 100-400L at 400mm and has the added advantage of 400-600mm.  Also its a regular twist zoom.

  • The canon 100-400 will give you a picture that can be cropped to show more detail than the Sigma 150-500. There is a new Tamron 150-600mm lens that may be what your are looking for.  It is priced ...
  • Fortunately it is nothing like the Sigma 150-500.  Very much like your Canon 100-400 with an extra 200 mm.  Reviews of the Tamron from people who have used it have been very positive.   Now that ...
