One of the key dif­fer­ences be­tween the D3400 and the ex­ist­ing D3300 is the in­clu­sion of Nikon’s SnapBridge wire­less im­age trans­fer tech­nol­ogy, first seen on the Nikon D500. SnapBridge is de­signed to over­come the re­stric­tions of con­ven­tional Wi-Fi, which is very ef­fec­tive for wire­less im­age trans­fer and cam­era con­trol, but is not an ‘al­ways-on’ tech­nol­ogy. When­ever you want to use it af­ter a gap, you have to man­u­ally re-en­able the Wi-Fi con­nec­tion. SnapBridge gets round this by adding a Blue­tooth LE (Low En­ergy) chip for a gen­uine al­ways-on con­nec­tion. On the D500, the Blue­tooth takes care of au­to­matic low-res­o­lu­tion im­age trans­fer to a smart de­vice (per­fect for Face­book and other so­cial me­dia), switch­ing to Wi-Fi for full-res­o­lu­tion images and re­mote cam­era con­trol. The new D3400 does not, how­ever, have Wi-Fi, so the SnapBridge ver­sion in­cluded here is Blue­tooth-only. You get the au­to­matic low­er­res­o­lu­tion im­age trans­fer to a smart de­vice, but not full­res­o­lu­tion im­age trans­fer or re­mote cam­era con­trol.
