If someone were to start doing single-person speaking videos using a 6D what might be the mic to get and what nice and easy light would be good to consider? Also, 40mm pancake lens (or another to recommend)?
I've bought all these and use them every week:

Any kind of shotgun mic will work probably, this is the one I use: https://www.bhphotovideo.com/c/product/300615-REG/Audio_Technica_AT897_AT897_Short_Condenser.html?sts=pi
It occurred to me that I'll often need my camera in hand for demonstration purposes so I'll need a 2nd camera of some sort. Regardless of what that'll be I'll need lighting so I just got the Genaray LED-7100T before seeing your post.
I already have an inexpensive, but not too bad camcorder (although without a mic input) that I'll likely get started with. Then, it's off to figuring out whether to get another DSLR or camcorder and then there's a few common mic suggestions that many seem to make (one being yours).
