hoppyman Posted January 25, 2011 Share #121 Posted January 25, 2011 Advertisement (gone after registration) Something is very wrong somewhere there. You are describing seeing a problem even with a 50mm. The first thing I would do would be to check all of my camera settings. Are you using any filters? Can you share your developing settings? Here's my Summicron 28 ASPH in very contrasty mid-day light. (uncropped) All I see is the characteristic vignetting/polarising effect that I got on slide film previously. I rather like it for blue skies. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Advertisement Posted January 25, 2011 Posted January 25, 2011 Hi hoppyman, Take a look here M9 and Red Edge Redux--Part II, with 28mm Elmarit?. I'm sure you'll find what you were looking for!
wattsy Posted January 25, 2011 Share #122 Posted January 25, 2011 Then you are very lucky since my 28mm Summicron shows the "Italian flag" effect in spades. The guy who sold me the lens says he never experienced the problem on his M9. LIke Hoppyman, I don't seem to have the Italian flag problem with the 28mm Summicron either. I get gobs of vignetting but I don't seem to have a problem with red and green edges (that I've noticed). The snapshot below would be one where I might expect to see a problem.

UliWer Posted January 25, 2011 Share #123 Posted January 25, 2011 Something is very wrong somewhere there. You are describing seeing a problem even with a 50mm. ... Not necessarily wrong, for the whole red-edge thing is very strange. If you look at Sean Reid's comparisons for different lenses (35 and 50) you'll see that he notices a red shift towards the edges (on white surfaces) with automatic lens correction. Therefor he gives the advise to switch lens correction off for 50mm. If you use lens correction with 50mm the red shift won't be visible on real photos, but there is "something." On the other hand, I have regularly seen evident red shifts with the 3.8/18 with the M8 as well as the M9. Last sunday I took more than 20 exposures with the M9 and this lens - there is no trace of any red shift or red edges on one of them. The whole issue very much depends on the "quality" of the light - though we don't know what it is. Link to post Share on other sites More sharing options...

pelagia Posted January 25, 2011 Share #125 Posted January 25, 2011 And I clearly see the reddish vignetting at the left side of Geoff's pine picture from the 12th December. Link to post Share on other sites More sharing options...
UliWer Posted January 25, 2011 Share #126 Posted January 25, 2011 And I clearly see the reddish vignetting at the left side of Geoff's pine picture from the 12th December. Mhhh, I don't. I'd guess some vignetting in the upper right corner, but wouldn't call it reddish. On wattsy's sea picture there seems to be a slight reddish touch, but this may be the result of monitor calibration. You'd have to measure the RGB-values in the different parts of the pictures. Link to post Share on other sites More sharing options...
wattsy Posted January 25, 2011 Share #127 Posted January 25, 2011 Advertisement (gone after registration) I am on a laptop,but I fancy I see a slight bit of red edge here,Ian. Maybe. I can't see anything significant on my main monitor or on my iPad. Either way, I don't seem to have the problem that Martin demonstrates in post #120 (nor does Hoppyman).

thighslapper Posted January 25, 2011 Share #130 Posted January 25, 2011 Cant see any any trace of red edging on my imac for either of the images (pines and snow)... and the residual vignetting is unobtrusive and if anything helps to 'frame' the images.

ho_co Posted January 25, 2011 Share #131 Posted January 25, 2011 We're again at "My lens does it"--"My lens doesn't." Although our own individual experience is what counts for us, it won't solve the global problem. Red Edge is a fact of life with some bodies and some lenses, not only Leica's. Please consider Bob's "reality check" at http://www.l-camera-forum.com/leica-forum/leica-m9-forum/161677-red-edge-redux-part-iii-2.html#post1584864, get with the plan and quit worrying.

hoppyman Posted January 25, 2011 Share #134 Posted January 25, 2011 My mistake. I mis-read what you said regarding the 50 and 35. My apologies for confusing the issue there. The central point is that we are showing very different results from our 28's (and from my 24 and 35 too as well as every lens down to 18 on my M8). Lots of theories and speculation and I try to avoid joining that. What we do know is that different users are reporting very different outcomes but of course the subjects/light, exposure decisions and possibly camera settings/ filters and importantly developing are large variables. We also have Leica Camera's useful and candid response. To avoid any confusion (I don't know if you were referring to my posting) - I can only see the problem with the 28 Cron, never ever with the 50 Cron or 35 Cron IV.

Washington Posted January 26, 2011 Share #136 Posted January 26, 2011 Dear albireo-double: I'm sorry if you took my comments personally as I was just frustrated with the whole issue. Naturally, if you believe you have a serious problem with your Leica you should indeed have it checked out. But, look at the number of posts showing a red fringe issue. I accept it as a fact of life and I do not correct everything I shoot.... I correct only that which I feel is a good photograph worthy of time spend. No offense, honest. Cheers.

wlaidlaw Posted January 26, 2011 Share #137 Posted January 26, 2011 I strongly agree - this is simply a non-issue for ANY lens on the M9. I use it mostly for the VC 12 mm Heliar.Bill I equally strongly disagree that it is a "non issue". If you have done a big shoot changing lenses frequently and need to get the results out quickly, correcting the various photos differentially in either Corner Fix or as I do, with lens profiles in C1 V6, is a total pain in the proverbial. I personally find the asymmetric vignetting, particularly with the WATE, slightly more of an issue than the red edges. I have to admit to being a tad disappointed in the long wait for a firmware update for M9, which I hope will go some way to alleviating both of these issues. On the last FW update, for some reason, the WATE was not one of the lenses which had its internal camera profile altered, according to the FW notes.

Washington Posted January 26, 2011 Share #138 Posted January 26, 2011 I do not how any firmware update can change the relationship between the lens and the sensor which I think is a major player in all of this. But, as they say: never say never! Good luck Leica! Link to post Share on other sites More sharing options...

Olsen Posted January 26, 2011 Share #140 Posted January 26, 2011 Have anyone been in contact with Leica regarding the 'Italian Flag Issue'? To me it seems to come and go. Not only with different lenses, but light/weather situations. Bright light and snow scenes seems to be the most vulnurable. Regardless of brand of optics. Nor do I think that this can be solved by a software upgrade. At least not completely. If it can't be solved with a up grade, then Leica should come up with some sort of PP software fix and recommendation. Link to post Share on other sites More sharing options...
