Primo Phantom Power New Sony Cameras


Testing stereo Primo EM272 microphones plugged right into a Sony A7III camera this time filmin fall foliage half an hour before sunset in Holland. The right audio level is substantially higher than the left channel level. I restored stereo balance editing in Final Cut Pro X : changing Pan settings to Stereo Left/Right shifting -50% direction left channel. The same effect was noticed again today with the stereo Primos plugged in my Sony ZV-1 camera – as reported before over the past days (though then with an angle adaptor in between). The problem did not occur when testing today the Sennheiser MKE 440 stereo mic plugged the same wayy in both cameras – so the imbalance is not due to some mechanical problem with the 3.5 mm plug port of the cameras.
Further stereo balance of the Primo EM272 microphones was perfect in audiorecorders – the Olympus LS-P4 tested today , and my old (2008) LS10 tested some days ago.
For now , I conclude the imbalance is somehow related with / due to the plug-in-power needed by the Primo mics from the camras – the Sennheiser doesn’t require plugin power… Note the required Phantom power (Plug-in-power) is no handicap with the dedicated audiorecorders.

Sensor


① memo 20180315 ~ Sensor ~ First shot yesterday with a new Sony Alpha A7 mark III camera , inspecting the sensor for dust over the blue sky, and focussing on some clouds – using a Sony FE 55mm F/1.8 prime lens at F11 with continuous autofocus. Later that day of testing and customizing this camera , I learned this new camera’s image quality probably equals the quality in low light of my Sony A7S mark II camera (with the Sony FE 28mm F2 prime lens) , and with a far better focussing experience with this camera/lens combination – accurate portrait auto focussing in the dark – a delight to use !
