Two (single) shots from yesterday morning with the Fuji X-T5 on the Nikkor 500mm.

The first picture was taken with the 1.7 teleconverter on the Nikkor. So the focal length is 850mm.

The second one was taken with the Nikkor and a Kenko 2.0 plus a Kenko 1.5 teleconverter. That gives a focal length of 1500mm with the Nikkor. Of course the sharpness decreases, but less than expected.
