Is it just me, or do you also think camera manufacturers are missing a trick? If I take a video I do not want to hear myself talking but i want to hear on the video what is going on in front of me, sometimes 20 yards in front of me, so why do all the microphones point upwards?
Sure with todays technology it might be possible the characteristics are so that they "listen" more forward, none of my cameras seem to do this, though.
So why dont they build them pointing together with the lens, forward?
Because directional microphones are typically bulky (think shotgun microphone or parabolic reflector) and are a lot more tricky to use than tele lenses.
Get yourself a radio mic (Sony has a bluetooth model), even a poor one will give much, much better results than a shotgun microphone.
