2 weeks ago i became the owner of a 1D 3 (had a 7D)i really like the IQ compared to the 7D.
Now i am thinking of getting a Canon 100-400 and trade in my 70-200 2.8 l.
I have a 24-105 F4 so i will have a nice range for outdoor sports and wildlife.
But still in doubt.
Would it be wise to switch these two lenses or can i bether get a tc 2.0?
(still trying to get a foto posted)
In my opinion the 1.4X TC are fine, but even I see a negative effect when I try a 2.0X TC. Without a TC, my 100-400 works very nicely on the 1DM3.
On your 1DM3, the 24-105 and 100-400 allow you to cover an effective field of view of 32-520mm at f/4 to f/5.6 maximum. If you need longer (narrower field of view), a 1.4X would extend that to 728 at f/8. That's pretty long ...
