More tests, but @ 400mm (large)

OK, while I had the test bed set up, just for grins I shot the 300 with a 1.4 TC (420mm) , the 200-400 @ 400mm, and the 400 afs2 --- all at f4.

Same conditions as previous test. 100% crops. Exif is in em. Jemini, you're right about the zoom vs the 300 with TC -- it may surprise some folks.

Hope they're of interest.

300VR w/1.4 TC (420mm) @f4

200-400 @400mm f4

400 afs2 @f4

My take is the zoom certainly holds its own. The 300 w/TC looks comparitively weak IMO. But I'd still take it in-focus vs either of the other two out

best, mark
