You get a lot of seriously good kit for your money. For starters, the 24MP sensor is capable of producing excellent levels of detail that gives beginner users who are short on lenses the double benefit of being able to crop into the scene for extra reach if needed.
Updating the user interface to give it a crisp and clean look is also a smart move – most of the other manufacturers have stuck with the same UI for some time now, and some are starting to look a little dated. The Guide Mode continues to be something which makes this camera appealing to novice users as well, not having to dig out the manual or search online for help is especially useful when you're out shooting with the camera and get a little stuck.
It's a bit of a shame that this camera doesn't have built-in Wi-Fi connectivity, as this would probably have been even more enticing to beginner users who are used to sharing their shots instantly from smartphones - those that hanker for that might want to look at the D3400.
There's also no touch or articulating screen, which is perhaps to be expected at this price point, but does make some of the entry-level compact system cameras which do offer this functionality all the more appealing.
The entry level market is likely to continue to be hotly contested, but Nikon shows no sign of losing its grip on this very important market.
In a nutshell, the D3400 is an excellent choice for those who want to purchase their first DSLR.
