A few things:<p>- Sony makes great cameras but the lenses are expensive. You can get an old Panasonic GH3 and a camlink and the lenses will be cheaper, while the image quality won't (for this sort of use) be affected much at all.<p>- You don't need a freakin' SM7B for this stuff. I do audio engineering as one of my too-many side gigs and the <i>most expensive</i> microphone I own is the Synco D2, an interesting little MKH416 knockoff shotgun microphone. It was $225. It's above my head right now, I was on a call an hour ago. It's out of frame and it sounds great. While the PR40 (which personally I prefer to a SM7B) or the SM7B are great mics for what they are, the delta between them and much cheaper competitors is not that significant.<p>- You don't really need hardware to tune your audio stack, aside possibly from a preamp if you bought the wrong microphone (in this case, defined as "the SM7B"). Use your computer. It's fast enough, it can save multiple presets, and it will <i>get out of your way</i>.<p>- Software matters. I use vMix for everything: live streaming and recording. <i>This</i> is where I recommend spending money. vMix has a reasonably featured (for the purpose--videography and audio to go with it) audio system, able to use ASIO with Windows and to use VSTs. It can support half a dozen cameras (my road kit uses 4, my home setup uses 6) and as many voices as your interface can, while supporting multi-record for archival footage/alternate takes and a nice tablet-control interface that's topped only by Logic Remote in this space (and if you're only doing audio, Logic Pro on a Mac is a no-brainer).
