Olsen Posted January 25, 2011 Share #1 Posted January 25, 2011 Advertisement (gone after registration) Took my M9 out for a spin with the Super Wide-Heliar 15 mm 4,5 Aspherical today. That was only a partly success. What is this red band along the left short side of the frame? I have seen others here complain about this too. What is the cause? Welcome, dear visitor!

Advertisement Posted January 25, 2011 Posted January 25, 2011 Hi Olsen, Take a look here M9/VC15 mm + red edge. I'm sure you'll find what you were looking for!
adan Posted January 25, 2011 Share #2 Posted January 25, 2011 "What's the cause?" has not be determined despite 15 months and probably 3,000 individual posts on the subject. Lots of theories, though. Search this site for "red edge." Also "Corner Fix" A rough approximation would be - Leica makes firmware corrections to fix the odd effects of using wide lenses designed for film that sit very close to a digital sensor, and the corrections are not yet perfect, even for some of Leica's own lenses (let alone 3rd-party c/v or Zeiss lenses, which are not Leica's problem). The heart of the mystery is - Why only on one side (always the left)? Again - lots of theories, but no definitive smoking gun. Link to post Share on other sites More sharing options...
Olsen Posted January 25, 2011 Author Share #3 Posted January 25, 2011 I don't know if I want to laugh of cry. I said to myself that 'if' I buy a M9 I don't want to be a beta tester this time. Well. I have not tested my M9 with my WATE. I will try to test it under similar circumstances and see what kind of result I get. Link to post Share on other sites More sharing options...
Olsen Posted January 25, 2011 Author Share #4 Posted January 25, 2011 I have downloaded CornerFix. How do I use it? Link to post Share on other sites More sharing options...
Wowmeta Posted January 25, 2011 Share #5 Posted January 25, 2011 I have downloaded CornerFix. How do I use it? Create a new Lensprofile with a Picture of a white Wall. Save the Profile. Open you Image with File Open and wait. In the right Side you can see the corrected Image - save as a new File. Make Profiles for your Lenses and save these. Have Fun and sorry for my bad English...

DennisK Posted January 25, 2011 Share #6 Posted January 25, 2011 If you use Capture One Pro as your raw developer you can also use the LCC feature to get rid of the color cast. It's more or less the same as corner fix but blends in with the workflow and works very well. Link to post Share on other sites More sharing options...
ho_co Posted January 25, 2011 Share #7 Posted January 25, 2011 Advertisement (gone after registration) Olsen, the instructions that come with CornerFix are simple and complete. As for being a "beta tester," I'm sure you're aware that this isn't an "M9 problem." CornerFix handles a number of other brands' RAW files as well. You can learn about many people's hopes and fears on the topic by doing as Andy said. To clear the brain after that, I recommend Bob's "Reality check," http://www.l-camera-forum.com/leica-forum/leica-m9-forum/161677-red-edge-redux-part-iii-post1584864.html?highlight=lcc#post1584864.

This is indeed a M9 problem! The M9 is my 4th Full Frame digital camera, not my M8 included. None of the others (1Ds, 1Ds II and 1Ds III) had anything near this problem! They had no problems at all! OK, I will test out my M9 with my WATE tomorrow. If this produces the same result my whole M-gear might be up for sale. This does it! Link to post Share on other sites More sharing options...

BillCB Posted January 26, 2011 Share #10 Posted January 26, 2011 Took my M9 out for a spin with the Super Wide-Heliar 15 mm 4,5 Aspherical today. That was only a partly success. What is this red band along the left short side of the frame? I have seen others here complain about this too. What is the cause? This is price you pay for having such a compact full frame camera that does not use retro-focus lenses. The rear element is very close to the sensor so light reaches the corners at a very acute angle to the microlenses of the sensor. There is usually cyan on the right and red on the left. I use the LCC (Lens Calibration) feature of Capture One 6. Does a great job. You need to create a profile just once for each lens. (In theory you make a profile for each f stop but I find that unnecessary.) I use it for the 12 mm VC Heliar. The camera seems to compensate adequately for most Leica wide-angles.

What is this red band along the left short side of the frame? I have seen others here complain about this too. What is the cause? Here's a 12 mm Heliar shot. Straight out of the camera, C1 defaults only. The red is not very visible in this small jpg but it's very clear in the full tiff. The second one was corrected with LCC in C1. Both shots had +2/3 stop exposure compensation. (Incidentally, it was -24C!) The sun was setting to the right, hence the brighter sky there. Welcome, dear visitor!

Since YOU have never had a camera that has this problem before, CLEARLY IT'S AN M9 PROBLEM. Yeah, that's solid reasoning. Don't bother to get informed. You haven't got your head around the issue; but that might be good for Maurizio and me. PM me as well when you dump the Leica stuff! Link to post Share on other sites More sharing options...
deirdre Posted January 26, 2011 Share #13 Posted January 26, 2011 And here I thought this was a physics problem. Link to post Share on other sites More sharing options...
thighslapper Posted January 26, 2011 Share #14 Posted January 26, 2011 Add me to the queue with maurizio and howard if you find the issues with ultra wide angle non Leica lenses unacceptable and dump all your gear in a fit of pique..... I could do with a cheap 2nd hand WATE....... This issue has been done to death and I have personally given up speculating on the physics/mechanics/optics that generate it. I've yet to see it on any of my lenses in 5k pics including a lot with the 18/3.8 I asked Kodak for some info but they politely referred my enquiries back to Leica.... Herr Daniels promised better correction in the next firmware this year.... but that probably will not help non-leica wide angle lens users.....

You haven't got your head around the issue; but that might be good for Maurizio and me. PM me as well when you dump the Leica stuff! I know that this has been a problem with certain digital backs. That is because these back producers are small scale producers with limited resources to spend on product development. And, obviously, that is also the case for Leica. I should have known. Japanese producers get subsidised governmental support for product development (like the US weapons industry) because 'digital cameras' are within the 'governments strategic scoop of products'. Add to that that Canon has earned 80% of the total 'world camera business'. And Leica made no profit at all.... So, the M9 Red Edge is a problem we have to live with because Leica don't have the resources to fix it.... I have had a very busy day today. Went to work before the sun got up this morning here in Oslo, and have come home just now, after sunset. So, I have not had the chance to do similar tests with my other lenses, except for one early morning 'snap shot' out of the window this morning. To my relief, my WATE seems to produce OK pictures with no red edge, as far as I can see. I am relieved. I am sure that Leica's service department will not cry themselves to sleep over that my VC 15 'does not work properly' on my M9.... Link to post Share on other sites More sharing options...
mjh Posted January 26, 2011 Share #17 Posted January 26, 2011 So, the M9 Red Edge is a problem we have to live with because Leica don't have the resources to fix it.... While we don’t know much about the nature of the problem – it is still quite mysterious – a lack of resources doesn’t appear to be the issue at all. You only start worrying about resources once you know exactly what to – but it doesn’t look like we were there just yet. Link to post Share on other sites More sharing options...
Jerry_R Posted January 26, 2011 Share #18 Posted January 26, 2011 And in order to know exactly what to do - you need resources (eg. for investigation, tests, etc.), don't you? Or buy knwoledge externally (if exists at all). Link to post Share on other sites More sharing options...
