1. Introduction
This manual provides essential instructions for the safe and effective use of your Nikon D3400 Digital SLR camera. The Nikon D3400 is a compact and versatile camera featuring a DX-format 24.2 megapixel CMOS sensor and EXPEED 4 image processor. It is designed for high-resolution imaging, notable low-light sensitivity, continuous shooting, and full HD 1080p video recording. The camera's sensor design omits the optical low-pass filter for enhanced sharpness and resolution. It also includes SnapBridge Bluetooth connectivity for wireless image sharing.
Included with your D3400 camera body is the AF-P DX NIKKOR 18-55mm f/3.5-5.6 VR lens, a standard zoom lens with a 35mm-equivalent focal length range of 27-82.5mm. This lens features a pulse stepping motor for smooth, fast, and quiet autofocus, and a robust VR (Vibration Reduction) image stabilization system to minimize camera shake.
