I never got to use my 400 2.8 and traded it in for a 600 f4, which I received last week.
This is one amazing lens. The weight is less than what I expected, though still more than what I can casually walk around with. However, I can definitely hand hold it for a few minutes. It focuses quickly as expected, the images are super sharp.
What really blows my mind is how good it is with Sony's TCs. I had used the 1.4x with my 100-400 but felt it did affect the sharpness a tad. And I never really used the 2X because my experience with the Canon versions was so bad in the past.
I just did some very quick tests in the backyard and the results are quite impressive. See if you can figure out which one is at what focal length. I focused on the left eye of the figure and what is also interesting is that the camera used eye-AF to do this, even though it is not really a living human.
One is taken with the lens at 600mm (bare lens), another at 840mm and the third is at 1200mm. Can you tell the difference?
