Sharpness at 100mm

To examine sharpness, the Nikkor AF-P 70-300mm lens was attached to a Nikon D7500 body, which in turn was mounted on a sturdy tripod. Exposure delay mode was activated to prevent further camera movement. Any changes in tone and colour across the images is due to changes in natural light during the session.
