Remember the recommendation for handhold shooting: shutter speed >= 1/focal length
Focal length here is minimum 150mm*2 (from TC) = 300mm or maximum 500mm*2 (from TC) = 1000mm. Unless you use 1/300s or 1/1000s shutter speed you must use tripod, no chance to handhold a shot with such a small FOV. Object distance is irrelevant, what matters is focal length and the resulting FOV.
