This is really exciting. Sennheiser announced their new shotgun mic, the Sennheiser MKE 600, very recently and you can be among the first to get one. It's available at B&H, the first retailer to stock and ship the new mic. You can order yours by clicking here.
The reason I said it was so exciting was that I have stated that my "desert island mic" was the Sennheiser MKH 416 shotgun mic (see my review, along with audio and video samples here: https://www.homebrewaudio.com/sennheiser-mkh-416-shotgun-microphone-review/). But that one costs about a thousand clams. If the new MKE 600 sounds anywhere near as good as the MKH 416, it will be a fantastic value at just $399.95. Plus I can justify that to my wife a lot easier than the grand I'd have to drop for the 416;).
One feature of the MKE 600 that I like a lot is that it can use phantom power or a battery. That is VERY significant and convenient for a mic designed to be primarily used for video because most video cameras don't have phantom power available on them for microphones. Heck, just finding a video recorder with an external mic hookup is hard enough. When I recorded the videos for the review of the 416, I had to use a separate phantom power unit plugged into a wall to power the mic. The MKE 600 also has a low-battery indicator so your audio won't suddenly cut out on you in the middle of a shoot.
