jbfilm Posted March 15, 2007 Share #1 Posted March 15, 2007 Advertisement (gone after registration) Went out shooting with an M7 and Elmarit 24mm ASPH. The lens had a 486 filter that I did not think to take out. Look at the cyan cast on the right (stronger) and left side of the image. All my Photographs with the 24mm + 486 had that...NOT the ones taken with the Noctilux. I'm sure that I did not just discover this.. but your input would help. Thanks Welcome, dear visitor!

Advertisement Posted March 15, 2007 Posted March 15, 2007 Hi jbfilm, Take a look here 486 IR cut Filter on an Elmarit 24 ASPH on an M7. I'm sure you'll find what you were looking for!
pascal_meheut Posted March 15, 2007 Share #2 Posted March 15, 2007 Yes, the IR filters create cyan shift in the corners with wide-angles. Nothing new. Link to post Share on other sites More sharing options...

Thanks This problem will be solved for coded lenses when firmware version 1.1 is released. This is scheduled for mid April 2007. This issue has been known for some time and if you do a search on IR Filters or Cyan Drift you should have plenty to read for a few days WoodySpedden Link to post Share on other sites More sharing options...

stunsworth Posted March 15, 2007 Share #6 Posted March 15, 2007 Jean you can use the free Panotools Photoshop plugin to correct this, but I don't have the URL to hand. Anyone? Link to post Share on other sites More sharing options...

billh Posted March 15, 2007 Share #8 Posted March 15, 2007 That brings up an interesting question - I leave the IR filters attached to my lenses - do I really need them outside in daylight, or only indoors with incandescent lighting? Has anyone bothered to shoot scenes with and without these filters? Link to post Share on other sites More sharing options...
woodyspedden Posted March 15, 2007 Share #9 Posted March 15, 2007 Woody: M7 The firmware update won't solve this. Whoops, my bad about the M7. Should have read more carefully. However since we know the Cyan cast is caused by the IR Filter and since there is no need for the IR Filter on the M7 the solution is at least easy........take the filter off! Don't you wish all M problems were this simple to resolve. Thanks for the catch Carsten Woody Link to post Share on other sites More sharing options...
lct Posted March 15, 2007 Share #10 Posted March 15, 2007 Why using those filters with film cameras? Masochism? Link to post Share on other sites More sharing options...
stunsworth Posted March 15, 2007 Share #11 Posted March 15, 2007 Bill you need them indoors and out. At least that's been my experience. Link to post Share on other sites More sharing options...
scho Posted March 15, 2007 Share #12 Posted March 15, 2007 Is your 24 Elmarit coded? If yes, the simply set lens detection to ON in the camera menu. The current firmware (1.092) already has some capability to correct for this problem.

blakley Posted March 15, 2007 Share #13 Posted March 15, 2007 That brings up an interesting question - I leave the IR filters attached to my lenses - do I really need them outside in daylight, or only indoors with incandescent lighting? Has anyone bothered to shoot scenes with and without these filters? My experience is that you need them outdoors too. Foliage in particular gives weird results with the M8 because some plants reflect a lot of IR (resulting in a yellowing of their greens and overall brightening relative to what the eye sees) and others reflect very little.

philipotto Posted March 16, 2007 Share #14 Posted March 16, 2007 Love the photograph. I am surprised no one has commented on it. Colours, I didn't pick up on the cyan for a bit, and if you don't focus on technical error of it, I think it actually adds to the colours. Subject, sweet smile, nice 2+1 grouping. Framing, tight, good perspective and angle. Backround, lovely, boards on the right are perfect. Link to post Share on other sites More sharing options...

ho_co Posted March 16, 2007 Share #16 Posted March 16, 2007 Jean-- Maybe you can send the M7 back to Solms to have it updated to take the latest firmware? What with the free time they've got right now, it shouldn't take them more than a year to get the modification done. Link to post Share on other sites More sharing options...
