sean_reid Posted November 7, 2006 Share #61 Posted November 7, 2006 Advertisement (gone after registration) Rex I totally agree. if the green ghosting was actually a reflection, the shape of the lenses rear element would at least distort the reflection slightly. Also it would be elongated as it approached the outer edge of the frame. I'm not seeing that happen, this seems to be a perfect digital flip of the original shape. Someone should do a test with a lens that has a convex rear element. Or its possibly (not sure how) that the .5mil glass over the sensor surface is doing this. But that seems less likely to me. I really can't wait for Leica's response to all this. _mike Leica has responded. They're working to see if this is a problem that can be solved via a firmware revision.

mike prevette Posted November 7, 2006 Share #62 Posted November 7, 2006 Thanks for the update Sean. I really appreciate all your leg work on this. In the days before the internet you could have never expected a company to have such great contact with communities of users. _mike Link to post Share on other sites More sharing options...
marknorton Posted November 7, 2006 Share #63 Posted November 7, 2006 This is no reflection. Forget filters, lens flare, etc, etc. This is a sensor/firmware artifact. The interesting thing is the banding never mirrors. Only the bloomed highlights mirror. Feed for thought I really think that this is a problem correctable in firmware. This looks like a timing issue and the timing chip is programmable. I wouod find it difficult to believe that Kodak could have produced a chip with such an obvious defect especially since it is 2nd generation. Hope springith eternal Rex Rex, I agree it's not a reflection - I have never thought or stated that - but I believe the banding and the green blobs are two different problems, one caused by the timing of the horizontal clock signals which opens a small window for the photo-site charge to leak along the row. The other, as I have explained elsewhere, is likely caused by unwanted interaction between the two output channels as the data is read out. If I am right - and short of taking my camera apart and hooking it up to a digital storage 'scope, it's tough to know - the banding problem may be fixable by changing the timing of the horizontal clock signals, if that can be done by re-programming the KSC-1000. I'm not so optimistic that the green blob problem can be fixed with firmware. Link to post Share on other sites More sharing options...
