I am 76 in good health but not super strong. I have used both the Tamron 150-600 and the Nikon 200-500 and found both to be a bit too bulky for me to handle comfortably over the course of a day. I find the 100-400 to be adequate when I feel the need for a zoom but no doubt there are times when doing wildlife with the 600mm and a big bird like a great blue heron comes close, I can only enjoy its passing. The 100-400 is quite sharp very fast for BIF and can get these larger guys quite well. There is always compromise
