Hi
It is typical to rolloff everything below 80Hz which does help with mic handling and other noise as well. Some mics have a switch on mic for that but you can do it in post as well. Doing it in mic is usually best but not a big deal. In mic so you don’t use up your gain on noise. But post mic if you want to play with the starting point and steepness of the rolloff in post.
Hope this helps
