Shutter life expectancy at DVinfo.net

I like making timelapses and wonder what the shutter life expectancy of the GH2 is; how many 'clicks'. Does anyone know? Can't find the answer when I google it...

If it's not published, then it's not published. Any number you get will be guesswork.

Considering most DSLR's are rated for about 100,000 shutter actuations, you can make your own guess.

Philip Bloom is a heavy user of time-lapses, and his GH1 and GH2 (except for the one at the bottom of Sidney Harbor) are all still working to my knowledge.

OK, really naive question here....but I'll go for it:

If the GH2 is mirrorless, is there still a life expectancy for the shutter?. Is anything actually moving when you press the button?

I do hear a click when I take a picture, but if there is no mirror - and the sensor is visible when taking the lens off - what moving parts are there to wear out?

Thanks,
Angelo

Take a still with the lens off, and you'll see the shutter.

The sensor is always exposed, and then when you fire the shutter, the shutter closes down first in preparation for the exposure, and then opens, and then closes just like any other camera, and then opens again to expose the shutter for the EVF. So for every still taken, the shutter actually fires _twice_.

In video mode, the physical shutter is not used at all.
