|Tamron 150-600mm f/5-6.3 Di VC USD lens|
Egami has uncovered a patent from Tamron for a 100-400mm f/4.5-6.3 VC lens. This is the most popular, medium focal length, zoom lens for wildlife photography and my personal favorite is the Canon EF 100-400mm f/4.5-5.6L IS II. I have taken this lens on worldwide photo shoots. You can see my equipment bag and works on MichaelDanielHo.com.
Tamron is a third party lens manufacturer and super long zoom lens is very popular. Canon is expected to announce their own Super Zoom lens some time n 2017.
