Exactly my point. A very obnoxious, intrusive shutter sound. Loud, long, slow, and clattery. Decibels are not a simple progression. The Olympus's shutter noise is approximately
one-fifteenth as loud as that of the Sony. So, is a shutter fifteen times louder than a competing mirrorless model a good thing? It's as loud as a big, honking Canon 1D-series with its flapping, high-speed mirror. And yet, the Sony has no mirror. Huh.
To me, the Sony's shutter sounds somewhat like a ponderous, vintage, cloth focal plane medium format SLR's shutter. But hey...great optics...interesting design...and best of all it's made by SONY. It's a nifty concept. If it took a lens mount that had some lenses, it might even sell well.
Noise Comparisons
It will be interesting to see what happens. Maybe it'll take the world by storm, the way Sony's a900 and a850 models did. Ot maybe it'll be a big sales hit, like the a99 was, with dozens of people buying it every day, all across Japan. It's just hard to know. The Fred Miranda cult of pixel-peeping landscapers with tens of thousands of dollars' worth of Leica M-series lenses might like it. People who can afford a $4,000 50mm lens might like it as a powerful statement of luxury and prestige. The sheer MTF 50 scores would earn the possessor of such a camera/lens combo high status in the measurebator's clubs.
