A:Answer Yes, the AF-P DX NIKKOR 70-300mm f/4.5-6.3G ED VR Lens (20062) is compatible with the D7100 with both autofocus and manual focus available. However, since this lens does not have a VR ON/OFF switch, VR (Vibration Reduction) will default to ON when used with this camera. In addition, the focus ring on the lens cannot be disabled when using the autofocus mode on this camera; the lens can be manually focused by using the focus ring. Updating the D7100's firmware to the most recent version is recommended. The most recent D7100 firmware, along with instructions on checking the firmware version and installing new firmware, can be found here: http://downloadcenter.nikonimglib.com/en/products/27/D7100.html . For a version of this lens without VR consider the AF-P DX NIKKOR 70-300mm f/4.5-6.3G ED
Lens (20061). Another alternative is the AF-P NIKKOR 70-300mm f/4.5-5.6E ED VR Lens (20068) which features a VR switch as well as a focus mode switch.
