Nikon d3100 is the best entry level nikon DSLR for beginners.
It has 24 MP, Having latest exceed 4 hardware technology, Having wifi support( not internally wifi, but you have to connect a adapter for it), not heavy in weight, having guide mode if you want to learn while you shoot, so many lenses are available for its model, has easy panorma feature, 5 frames per second, shoots movie in 60 spf and 30 spf., has 11 focus points.
I will strongly recommend this DSLR over d3000 and canon 1200d. As this model is the latest of all, and has latest expeed 4 hardware.
It also has a great battery life. approx it takes 700 photos when fully charged. Wifi feature is great. from it I transfer all my data to my mobile using wifi technology, so fast and no more tension of cables.
Price is also a great advantage. it dont costs too much. it costs around? 20000 if you buy it online.The only con in this DSLR is it does not have Flip out screen.( Nikon d5300 has flip out screen, but it costs more.) .
But flip out screen is not the necessity .
Verdict- Best DSLR for sure at entry level. strongly recommend to everyone. who are beginners. and will recommend above d3000 and 1200d.
