OK, apparently the different exposure causes quite a bit of confusion.

 

If it´s not cloudy tomorrow I will take the shots again.

Same exposure, same aperture, same angle, same light.

 

But sorry folks, one is a Nikon and a 28, the other one a Leica and a 35, nothing I can change here.

 

 

But don´t you think you miss the point here? Aren´t you as astound as I was when I saw the results?

 

"proves nothing"? I don´t think so.

 

 

Here another picture from the Nikon, in my opinion optically great,

then a Leica one in a church, even the window light from a cloudy day produced the problem + a crop for better visibility.

(grain added)

 

cheers, Heiko

I see from a few responses in this thread, it seems that the degree of chromatic aberration in blown out highlights varies from camera to camera and some M9 sensors seem more afflicted than others.

 

If this is a M9 sensor issue that is not equal in all M9 camera's is there any solution offered by Leica by sending the camera in for adjustment.

I am not sure that this is a senor problem.

 

It is most pronounced with open aperture. The more the aperture is closed the better the result gets. By 5.6 it starts to be usable, better at 11.

 

The amount of light hitting the sensor stays the same (with adjusted exposure time of course)

I understand it is most noticeable with the newer summilux lenses wide open at 1.4 and diminishes with each stop down

but it also seems related to the M9 sensor and it does not seem that every M9 has the problem to the same degree from some of the posts here

It varies with the raw converter as well - ACR is much better than Aperture and C1 beats both.

The better the lens responds to microcontrast, the more one will see this kind of effect. A tradeoff I fear. Get a softer lens and you will see less of these edge effects.

I sent mine for this issue. The reply is not what I would expect from Leica then:

"We suggest not to shoot against the sun at wider aperture" and I got my camera back.

 

Anyway, I repeat once again that purple fringing is a sensor issue, and it shows more evidently with fast and high contrast lenses (in high contrast scenes).

The Leica lens is just too sharp, has too much correction for what you want. Oh, and the tattooed girl really does have purple fringe in real life. :)

 

Have you tried a Softar filter or a soft lens?

Ok, here are the two photos I promised to take.

 

Same angle, same object. same ISO, same aperture, same exposure.

See for yourself, judge for yourself.

 

 

both ISO 200, aperture 1.8, 1/4000 of a second

shot directly into the sun, with the sun in the upper right corner

 

1: Leica 35 Summilux FLE

2: Leica crop

3: Nikon 28/1.8

4: nikon crop

 

 

cheers,

Hi

 

I am still not sure if it is just a sensor thing.

It is postulated that the FLE is too sharp, good, corrected etc...

 

but my Voigtländer produce far more CA then the FLE on the same body.

(50/1.1 and 35/1.4 MC)

Same angle, same object. same ISO, same aperture, same exposure. See for yourself, judge for yourself.

The Leica picture is sharp as tack, has magenta fringes in the foreground (which are easy to remove in post-processing) and virtually no fringes in the background.

 

The Nikon picture is sharp as Lomo, has orange fringes in the foreground (which are harder to remove in post-processing) and lots of green fringes in the background.

 

I'll take the Summilux, you can keep the Nikkor, thank you. The Nikon picture may look better at first sight—but when properly post-processed, the Leica picture will turn out better by an order of magnitude. Umm—the flare ... okay, that's not so nice but in the next picture, the Nikkor may flare more and the Summilux less. Flares come and go with tiny changes in the angle of light. Generally, my Summilux-M 35 mm Asph is very resistant to flare (albeit not totally immune—no lens is).

Interesting

 

I have to say if I had to choose a lens/camera combination to shoot that image I wouldn't take the M9 and 35mm Summilux ASPH.FLE, post processing in mind or not.

 

I guess the reality is either your M9 has sensor issues or the combination is inherently problematic. I'd value Leica's thoughts. It may well be the circumstantial combination in which case perhaps a softer lens might be better ?

My first thought is why one would want to take an image like this in the first place?:confused:

 

That was my thought as well.

 

If you want purple fringing, try shooting a Noct wide open against the light, or with highlights. I can't really think of a circumstance where I'd want to shoot wide against a strong light source - the two images above are not really pictures I'd ever take.

 

Fringing is a fact of life to be managed and avoided - so much of the rest of the Summilux image is really good.

 

Cheers

John
