It's a copy rather than a clone.
It's good value for money, though; but it's not a 416.
A Post Production engineer mixing a movie that had used both the NTG3 and the MKH416 posted his findings on Gearslutz HERE if you want to read an expert opinion of use in the real world.
I have also read about the NTG3 not liking the cold HERE.
the 416 is one is worse shotguns to work on film( aka cinema ) , the mic sound drastically changes when you 1 feet or 3 feet above the subject , extreme proximity effect and extremity tin sound when you 3 feet away .
Good for news and documentary where the only thing what counts, if you hear the person or not .
The ntg is a wide pattern mic , more close to sanken sc-3 and doesn't have so high fq pitch as sennheiser , works grate and could handle much grater spl .
about the guy who wrote the revue, did he really check who was recording the days with ntg , as it much important the person then the stupid tool .
under 600 , you can find used at 4073 with rode blimp - good enough for almost anything .
