Hi. Last weekend I shot some bands and some photos show this "color fog" you can see in attached pictures. All of those photos were shot with Zeiss Planar T* 85mm f/1.4 AEG (C/Y). Is there anything I can do to reduce this effect? I mean, except for not shooting against spotlights.

Yes, had one attached. The hood certainly does not help when shooting against the lights, as you see in the second picture. I was using 4 different lenses that evening and only the planar showed that fog... _________________ Holger

I'm not an expert on this lens but the fogging seems severe - is there any internal 'misting' I wonder.
I once had a 135mm f3.5 pre-set lens that gave similar results and found the problem there was a glossy black T2 adapter ring, but I wouldn't have thought your lens would have been made with a polished interior! _________________ Stephen

I can understand not wanting this effect all the time, but on those shots, especially the second, it adds a great rock'n'roll atmoshphere IMHO. |

Does the Zeiss have a fairly flat rear surface to the last element? This would make the effect worse.
Mind you, I would have thought the Zeiss would have a good anti-reflection coating on the rear element, which should prevent the reflections. Can you see if the rear element looks to have a good coating?

In this case, the "foggy" results are not that bad. Well, it's rock, and that fog add's to the atmosphere. But in general I don't want this effect. I don't have much time left to inspect this effect the next few days, but I'll keep you informed. Thanks for your responses! Really!
Forgot to add, no filter used... _________________ Holger

Yes, agreed! But I just want to understand why and when this effect occurs. I don't always shot rock bands, and i'd like to avoid this when I don't want it... _________________ Holger

The Planar 1.4/85 has a large front glass, and the T* coating, although undoubtedly the best there is, can not perform miracles: if you point this lens towards a strong light source, it will create some flares.
The point is the amount, which should not be as invasive as your photos show.
Try the lens in a daylight situation with a blue sky and bright sun, do some backlight photos, trying some different angles. Then let's see the results, I'll be able to tell you if your lens behaves normally for a 1.4/85 Planar or if there is some problem to it. _________________ Orio, Administrator

Going back to the original question and seeing the responses so far, in my estimation, there's not much you can do. You may want a better (technical) result, but I doubt any other lens could do it. In fact the majority would be much much worse. The conditions are really harsh like shooting into the sun on a hazy day.
Orio and "fuzzywuzzy" (I'm sorry I don't know your real name) are right. They have a great atmosphere. I appreciate that over technical, because the "art" is sometimes lost to us photography technophiles here. |

That's interesting, the other day I got some whacky rainbow flare on a lens with a badly fungused rear element.
This was taken at sunset, the sun is almost right behind the truck. I was going to try to duplicate this but yard work has consumed my sunny evenings lately.
edit - this is a 100% crop. FWIW the lens is a 200mm Nikkor Q, and I did use the built in lens hood. The lens is decently sharp when used in sensible lighting conditions and stopped down a bit. |

Very nice diffraction pattern. Note the cross shape - this means the diffraction is off a periodic structure with rectangular symmetry. The obvious candidate is the sensor itself.
I guess the bright spot of light from the reflection on the car is diffracting off the sensor and the diffraction pattern is being reflected back onto the sensor by the rear element in the lens.
