The Rode Procaster will sound better when used with the the Tascam DR-60D, but now it appears this Zoom H6 has become my favorite portable audio recorder. I'm sure people will complain about not being to lock the input gain dials on the H6, but compared to the H4n, I prefer the dials over the digital input adjustments on the H4n.
BTW, if you're in the Bay Area and looking for a Tascam DR-60D, i've got a barely used one for sale..
YouTube member blkphoto sends in this video test using the Rode SmartLAV while shooting with a Panasonic GH3 [Thanks Larry]. If you jump over to 1:43 in the video you can hear the immediate difference between the recording and the sound from the GH3 internal microphone.
The Rode SmartLav is a microphone that connects directly to an iPod touch, iPhone, or iPad. You can download a free version of the Rode Rec app to adjust sound levels and with the paid version of the app you can immediately share your recordings to the cloud.
It may not replace your other high end mics and digital recorders, but as you will often hear stories about Lav mics breaking in the middle of a project, it might be handy to keep a Rode SmartLAV around in the kit. Available at the DVEStore.com (found here)
