I must be having a major comprehension problem today. Why does it make "perfect sense from the standpoint of financial gain for Artie Morris"? What am I missing here? Is it because the combo (70-200+2xIII) makes Canon more profit allowing them to keep Mr. Morris employed?...I think Artie Morris is in an excellent position to provide insights and valuable comments - but his position as a salesman of Canon products means we should treat what he says with some degree of caution.
It's important to keep such motivations in mind. For example, his recommendation of the 70-200/2.8L IS II + 2xIII over the 100-400L...it doesn't make much sense from an optical, AF, or handling standpoint…but it makes perfect sense from the standpoint of financial gain for Artie Morris.
