Q: 7. Sony has three high resolution XLR microphones available: The EMC-100N, EMC-100U, and the C-100. I assume the C-100 is not good for field recording, so is either the EMC-100U or EMC-100N good for field recording? Alternately, are there any similar caliber microphones that are good for high resolution audio for field use?

A: It depends on what you intend to record. The EMC-100N is an omnidirectional mic, so if you intend to record a group of people or soundscape, that would be a good choice. The EMC-100U on the other hand is a cardioid pattern mic, so very good for single-subject or narrow-field recording. The C-100 is not really for field recording, more for studio work like voice over. A good choice for a mic that can do both is the Sony ECM-680S which is a switchable M/S Stereo mic that can be switched to unidirectional. https://www.bhphotovideo.com/c/product/514507-REG/Sony_ECM_680S_ECM_680S_M_S_Stereo_Shotgun.html
