Canon's 250mp 1.3 crop sensor. Why not today?

Why is it these things get confined to ultra-expensive scientific cameras? They can obviously make them just like other sensors, so perhaps 9/10 of them are too flawed to sell? Or, not, since they already produce smaller sensors with MUCH higher pixel densities. I would LOVE a sensor with that resolution (over twice that of a 50mp sensor). Why do you think that corporate anycountry, owes you anything. -- PeterN |

This could be one. Not some tiny, incremental boost in pixel count. In 2002 Canon released the 1ds and Kodak the DCS-14. It's taken 13 years for Canon to release a camera (5DS/R) with double the linear resolution of the 1Ds. Perhaps that's the kind of timescale you should be looking at for when Fx cameras might be available with double the linear resolution of current high resolution cameras. |

Perhaps that's the kind of timescale you should be looking at for when Fx cameras might be available with double the linear resolution of current high resolution cameras. If you've got a 1/2.3" P&S sensor with 16mp, is it that hard to translate resolution like that to an APS or even a FF sensor? What would that be, FF, 700mp? Totally diffraction limited at normal working apertures, probably all kinds of issues with offset microlens design/performance at that sensor size, FSI at a pixel pitch where circuits obstructing the light path would really be an issue, or BSI where light-bleed between the small pixels would be another issue. There's good argument why oversampling by the sensor is a good idea (having the system resolution limited by diffraction or lenses), but not if there are heavy penalties, not just including the obvious - trying to deal with the massive file size. |

In article , Me says...
Totally diffraction limited at normal working apertures I wonder if there is some way to get around the diffraction limit with some sophisticated image processing (sort of an in-camera deconvolution or something like that, having an exact diffraction effect model). -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

Yes, to a degree, but at the expense of more noise. -- Cheers, David Web: http://www.satsignal.eu |
