Hi, I'm actually planning on purchasing either of the lens for wildlife photography. For the 300mm I would be using it with a TC-20E III for the extra reach, equivalent to 900mm on a dx sensor. As for the 200-400mm I would couple it with a TC-14E II for a reach of approx 840mm on a dx sensor.
However, I've not managed to get hold of a 200-400 to test out personally for the image quality. Online reviews have said it to be comparable or at worst slightly lousier as compared to the 300mm f2.8 while allowing greater versatility due to the zoom. Thus, could some out there enlighten me on the image quality of both lens? And it possible offer comparisons between them please? Thanks.
