Hi,cheeyuin
Why not if someday we can achieve iso 12800 with NO NOISE.At the last pc fare fujifilm has one capable of iso 12800 but noise intro many colours in dark images.Nikon D3 boast of even iso 25600? but it seems its use even the infra portion of the spectrum to achieve that.Down the lane perhaps we may have iso25600 in ordinary camera at normal light and thats the time we astrographer will celebrate!Thanks.

Nikon's D3 ISO25,600 pales in comparison with the 1D MkIV with ISO 102,400. This is 2 stops more sensitive than Nikon's D3.superiorstream wrote:Hi,cheeyuin

Latest nikon d3s is also enhanced at 102,400 iso...and iso sensitivity of 12800 as a base.
Further more it is full frame...very nice for wide Cosmos field

looks like astrophotography has taken to a new level...

Hi,
1DM4 is a high performance DSLR which is not needed in Astrophotography. Too expensive to get it just for astro use. IMHO, if need good image quality, a 5D or 5DM2 is more than enough.
Anyway, ISO is important only in normal photography, but not that importance in Astrophotography. Also, increase ISO is actually increase the amplification of the signal output from the sensor before the signal get digitize... the sensitivity of a sensor does not change.
Have a nice day.

Bearing in mind that both Nikon D3s and Canon 1D Mk4 are designed for photojournalists, the additional functions available (and cost) may be a bit overkill for Astrophotography.
