Too little information.. as senator said.. if you want to buy it.. buy it..
What comes to endless variables that this job is associated with...
I try to quiz the following in my mind before considering renting/buying anything for a project .. and it's not in order any kind of;
- What type of project? Dirty ENG or indie or short or feature or documentary...? each have different needs..
- Location location location!! check out the INT./EXT.? locations.. acoustics (hello reverb), noise print, weather etc & relatively to shooting dates & times (hello wind and ocean waves!) ..
- What the production is doing... much wide shots? actor movements, positions etc. & WHO is going to swing those booms and how much spaces can be treated.. some mics are more forgiving and sometimes you run in the middle of 3 steadicams etc...
- Reliability.. humidity..? weather..? MKH416 is a solid tank! NTG3 is cheaper tank but wider pattern.. Sanken CS3e seems to be pretty sweet for weather.. MKH50 for "sweaty humid" indoors work like a treat..
- What does the post production require.. talk to the re-recording mixers etc. before the shoot about their earlier pains
- Is the mic going to be in "disaster zone" .. crash mics..
- Other environmentals etc max SPLs.. sometimes things like less self-noise is critical for quiet sources... Sanken CS3e is not for quiet sources IMHO..
and by no means not complete list.. I do like versatile mics but there is absolutely no one mic for every application..
