It’s a VERY solid mic for what it does well.
It has very low self noise. It has a crisp and smooth frequency response. And great off-axis rejection for it’s class.
The 416 excels as an overhead boom mic when used by a knowledgeable boom operator – particularly outdoors where ceiling and/or wall reflections are less an issue than in an indoor setting. But that’s room size and sonic reflection dependent.
It’s generally too long to camera mount. It’s a poor interview choice, again unless it’s boom mounted because it’s handling noise characteristics are pretty mediocre.
In sum, it’s a solid, proven performer in the specific area where the designers intended it for use.
As a general purpose videographier, after I owned a solid dynamic interview mic. A few solid lav mics – both wired and wireless. And perhaps a quality PZM plate – something like this would be my next purchase.
And i’d move it solidly in front of the PZM if most of my actual work was recording dialog for movie making.
FWIW.
