Sonys is a 100-400 like Nikon. The consumer 200-600 is not a comparable lens. There is more to a lens than its f-stop and focal range. That Sony is also equivalent to a 300mm when at 600mm and focusing on something close.When Sony and others have a faster 200-600 lens under 2000 with great optical quality and TC compatibility it didnt seem Canon was making a huge leap with the 100-500.
