Wonderful shots everyone! So what would the Tamron do for me but add a pound of weight?
For you, maybe nothing. For others that do not already own a 100-400 and a 1.4x TC, they would save $1130, get 600mm @ f6.3 instead of 560mm at f8, at a weight difference of only 3/4 of a pound more.
Compared to a 100-400 with a 2x TC, they would save even more money and weight would almost be the same.
In addition, the Tamron owners could go from 400 to 600mm, or from 600 to 400mm faster than anyone could put on or remove a TC.
