Advertisement Posted March 11, 2010 Posted March 11, 2010 Hi vanhulsenbeek, Take a look here Good news! M9 FW Update this week! (Merged). I'm sure you'll find what you were looking for!
Guest trond Posted March 11, 2010 Share #62  Posted March 11, 2010 First picture WATE at 16mm, second picture 21lux.  http://www.saether-online.com/red-edges/WATE-16mm.tif  http://www.saether-online.com/red-edges/Summilux-21mm.tif  Summilux is at f1.4, WATE at f5.6.  Color cast is clearly visible on the left side on both pictures on a properly calibrated monitor.  Sorry for the large TIFF files the effect is less visible on jpeg and sRGB.  Best regards  Trond Link to post Share on other sites More sharing options...
wlaidlaw Posted March 11, 2010 Share #63  Posted March 11, 2010 And this is what makes this interesting. I have tried two different WATEs and two different 21 'luxes and none of them have ever shown any red edge. The only Leica lens that I have been able to get to consistently show this is my 21mm Elmarit ASPH. Jeff  Jeff,  I originally thought "what are these guys talking about" with colour cast on the M9/WATE, because I just wasn't seeing them. Then I got some horrible pink edges in snow. I have come to the conclusion that the colour temperature of the incident light is the critical factor. High colour temperature and you get pink edges; lower colour temperatures and you barely see them. In a higher colour temperature lighting situation e.g. noon day light, if you take a picture of a white sheet, I am sure you will see pink edges.  Wilson Link to post Share on other sites More sharing options...

I am guessing if you do the same test at midday, you would see a much more prominent red edge. To my mind that makes the correction easier, as Leica could factor in the colour temperature from the AWB, to control to what extent they roll back the red channel amplification for the left edge.  Wilson Link to post Share on other sites More sharing options...
Guest trond Posted March 11, 2010 Share #67  Posted March 11, 2010 Advertisement (gone after registration) Dear Wilson,  The "tonight" test was done with a calibrated 6500K monitor as the white target.  This produces a diffuse light.  The red edges I have only seen in strong sunlit scenes with strong contrast.  Best regards  Trond Link to post Share on other sites More sharing options...

It didn't show up. I don't get snow in Los Angeles.  Jeff Link to post Share on other sites More sharing options...

neli Posted March 12, 2010 Share #76  Posted March 12, 2010 Well, as a long-time deadline-facing journalist - "by" March 15 to me means "before 23:59 (11:59 p.m. for us Yanks) on March 15. Probably well before, but perhaps not. It also would never occur to me that someone at Leica would NOT work through or on the weekend (if needed) and upload something at 11:59 pm Sunday, March 14 (or 4 am March 15 or whenever). The internet is 24/7.  I note Leica (purportedly) only lists current wide lenses as having improved corrections for red edges. I wonder what that means for my pre-ASPH 21 Elmarit.  I love deadlines, I love the sound they make as they go wooshing past - slight misquote Douglas Adams Link to post Share on other sites More sharing options...

sandymc Posted March 12, 2010 Share #78 Â Posted March 12, 2010 Re the red edge issue, I think the interesting part of the firmware updates is the "New ISO setting-related vignetting correction: strong correction at ISO 160, lowest ISO correction at 2500, interpolated for intermediate ISO steps."

And the sound of a room full of tape punches were similar to a shooting range....  We´ve come a long, long way...... Link to post Share on other sites More sharing options...
