How to prevent/fix

[RVT1K]

I've taken quite a few shots with this lens (Tamron 300mm f/2.8 with a 2x tele converter) but never had the color fringing issue before. My D4 "knows" its a non-cpu lens and "knows" it was using it.

So did I do something wrong? If so..what?

Or is there a way to fix it with my limited Elements skills?

I had a Tamron 300/2.8 back in the 1980's... when using the 2x converter that came with it, I got chromatic aberration, which as i recall was worse at wider apertures. I sold the lens off in 1990 or so.

So why haven't I seen this before?

Is it just a matter of the conditions being worst-case-scenario? It was totally overcast and I had the ISO jacked up to 8000. I usually wait for bright days if I can but the subject (a Northern Flicker) is a new arrival and I wanted to get something.

Tree branches against the sky or telephone wires against the sky is indeed one of the worst possible shooting scenarios. The addition of the teleconverter used to be the big problem with my Tamron 300 /2.8... whenever I used the converter I used to get a lot of color fringing.

I am not sure this is chromatic aberration. That purple fringing is sometimes called birefringence.

I used to own a Nikon 85 mm / 1.8 AF-D which had terrible purple fringing whenever I shot tree branches against the sky... my much newer 85 mm F 1.8 AF-S G did not have the same problem at all.

Thank you, sir.

Have you tried processing it in Nikon Capture NX-D? If not give it a try and look for Axial Colour Abberrations under the Camera and Lens Corrections.

Here is the result at 100%

That was my thinking as I read this. When shot wide open in bright light chromatic aberration is most noticeable on my Canon 85mm f1.8. Fortunately I would normally not use that lens in very bright conditions in favor of the 70-200 f 2.8 L which in regards to C.A. is near perfect.

Funny, I have not hit Post Reply and just scanned other replies and I see that @Derrel had the same experience with the Nikon 85mm equivalent.

I think C.A. reduction is something that is expensive to eliminate. In the case of the 85mm, I know about it use something else if I think it will be a problem for the conditions at hand. Still love that lens...in the right situations.

About 19 years ago I had the 85 mm F 1.8 AF, not the AF-d, and this was a number of years before the AF-S G was introduced.

I had a photo project of what I called my tree, in the backyard, I was photographing it from its winter twig state until its Blossom and later its fruit state.

The 85 mm AF was basically useless in this situation and gave extremely strong purple fringing on each and every one of probably 150 small Limbs and branches. The 70 to 200 VR-G did not have this problem. At that time software elimination of color fringing was quite a few years in the future.

I ended up giving the 85 to my friend back in 2001. Some lenses are very prone to this purple fringing.
