One of the best features of mirrorless cameras is their ability to shoot totally silently thanks to the lack of a mechanical mirror. That feature turned out to be a great boon to a photojournalist at the recent Democratic debate, allowing him to shoot in a position where others couldn't.
The Sony a9 is known for its electronic shutter with fast readout and no viewfinder blackout, which allows photographers to shoot in complete silence. For New York Times photographer Doug Mills, that became a great advantage at the recent Democratic debate. It turns out that the sound of the DSLRs used by other photojournalists was picked up by the broadcast microphones, leading NBC to tell them to only shoot during audience applause. When Mills was brought to the side of the stage for his turn, he was told he couldn't shoot, but he quickly explained that his camera didn't make any noise, leading the NBC tech to remark that such cameras should be standard for all photojournalists. If you've ever listened to any live political event, you've probably heard the constant clatter of DSLRs, so surely, an eventual migration to mirrorless cameras would be beneficial in that sense. Nonetheless, press companies are deeply invested in Canon and Nikon cameras and lenses, so such a change won't happen overnight.
