Features in Compact body, Solid autofocus system, huge battery life and very good image quality the Nikon D3400 are also incredible easy to use for the first time use. D3400 is the best budgeted Entry level DSLR camera. It is small size light weight and simple design. Overall this interchangeable lens camera delivered very good photo and quality video for its price. Same resolution is the D3300 for without anti alias filter for slightly unsharpened the image. D3400 delivered slightly sharper photos in low light. This is upgrade version of D3300. Maximum features are same but very little difference are notice. Five difference we have noticed between D3400 and D3300. D3400 is actually lighter then D3300 and D3400 included Sanpbridge system, which help to connect your smart phone to share camera photo. This advantage not included in D3300. D3300 comes with microphone jack but D3400 does not have microphone jack. If you are shooting a video, you can’t use external microphone jack. If you are you tuber than D3300 is better choice. Battery life is very good then D3300. You can shoot 1200 image with full charged battery. D3300 only 700 shoots.D3400 price little high. Rest all features are same. Both camera are delivered good quality photo and video. So choice up to you.
