According to Engadget “Sony reps on hand to acknowledge and confirm the issue, which seems to plague every [shoplink 8452]NEX-5N[/shoplink] that we’ve tried. This is still very fresh, so Sony doesn’t have a fix or even a statement to issue, but because 1080/60p video is one of this camera’s headline features, we’re going to recommend holding off on your purchase until the company can confirm what’s causing the issue.”
I hope Sony will prepare some kind of fix for all current [shoplink 8452]NEX-5n[/shoplink] owners (that includes me that just got the camera). It really makes no sense to offer FullHD recording when you cannot record audio because of that dummy CLICK noise!
