A9 Vulture no TC failed focus sequence

This is a sequence of shots taken with the A9, and the 200-600. The focal length was at 600mm, the lens was wide open at F6.3, and the shutter speed was 1/2000s and 6400. This was a large vulture flying slowly from right to left. It couldn’t be easier. Most of the series were out of focus, and the final AF point missed the bird in nearly every shot.

A9 Hawk misfocus

I tested the A9 with the 200-600 f5.6 plus the Sony 1.4 TC for the afternoon falcon flying, where a long focal length is required, and the Sony could in theory get out to 900mm . The falcon test is quite demanding as the bird flies incredibly fast, and at a long distance away. The starting position is usually known though so these are slightly easier shots than the kite feeding ones. The results were very poor, with the AF points all over the place, except on the bird.
