I look at it this way (and this is only my viewpoint): I have a 500 VI that I shot almost always with a 1.4x, giving my 700mm. I almost always shoot at f/8 for birds. The samples thus far are all wide open (I haven't seen anything shot at f/8) and thus far have all looked very good. So, f/8 should be better. As far as AF speed goes, given I'm shooting with a 1.4x, and judging by the speed of the new Tamron 70-200 VC, I would expect them to be very similar.
So what do I give up?...Show more →
Even with motorsports, f/8 is typically just fine, and is the reason I plan to pick up one of these Tamron's to use alongside my 400 DO with 1.4 TC, and we'll see if the Tamron can keep up with it throughout 2014. A big ask of it, but you never know.
