Game-changer: How about 8 stops faster ?

Saw this the other day: http://www.extremetech.com/extreme/1...ht-photography

If it makes it to production, it will revolutionise astrophotography but I'm not sure how the mass camera market will react.

1000x better is 8 stops. OK, so we could shoot landscapes by starlight at f/8 using ISO100.

For astrophotography, you won't really need to worry about PE as your exposures are only going to be a couple of seconds or less. Even tracking might be unnecessary, so even a dob could do astrophotography.

Conversely slow scopes like my f/15 Mak could do astrophotography (!) Hmmm....

But if you want to use long exposures to get the silky water look will need around 11-12 stops of ND filter... comparable to shooting through a solar filter (!).

And it poses problems for bokeh, where a fast lens around f/2 or 1.4 is needed... either the shutter speeds will have to be around a microsecond, or we'll have to learn to shoot portraits by moonlight.

Anyway seems like I'll forget about DSLR bodies until this happens.
