Someone at my work is offering me a sennheiser 415 MKH mic and I know the 416 is supposed to be one of the best in the buisness, but I don't really know much about the 415, is it still a solid mic? how much should I be willing to pay for it?
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.
