85mm f1.4 finging issue

wind30 · 28th November 2006

I just noticed that the 85mm f1.4 has some very noticeable fringing issue shooting at f1.4 for OOF stuff.

Photozone also noted this issue.

My sample

Even for such a reduced size sample, you can see the green fringe around the top of the chair. If you blow it up a little, it is very obvious.

Is this normal for all 85mm f1.4, ie can I hope to get a better sample?

Normally I shoot with f/2. This will reduce it or try not to shoot at contrasting subjects

I think it should be normal. Even the link you posted mentioned that it is common for large aperture lenses like this and the Canon 85/1.2L.

I am pretty happy with my lens. It is really quite sharp even at f1.4 even at the corners which is quite remarkable.

It is just the fringing which was unexpected.

Focusing at f1.4 seems to be easier than I expected. I thought the thin DOF is going to be more of a problem.

No.. The thin DOF makes it very much easier to put the focus where you want it to be.

soooooooooooooooooo cute!

thanks. My niece is really quite pretty. Eyes very

The fringing on high contrast out of focus areas is typical of this lens. Read somewhere that this is due to the IF design, and it appears to a greater or lesser degree in most IF design lenses.

wind30 · 28th November 2006

pity that this fact is not really highlighted on all the recommedations/discussions abt this lens, especially since this is supposedly one the best nikkor for bokeh, ie people recommed it for good bokeh.

Does the 105mm DC suffer from this?

But to be fair, all the other aspects of this lens is TOP NOTCH.

jeanie · 28th November 2006

i did read about this fringing issue which is why i held back on the 85 1.4.

still waiting for my dc.when i get my hands on it, i'll try and c.

jeanie · 29th November 2006

i finally got my DC lens today.yippee!

how do you guys wan me to test if i get the fringing thingy?

wind30 · 29th November 2006

post samples shot at f2 with some high contrast stuff at the OOF background.

Something similar to my shot lor. Something white on a black background.

BTW, where did you get your 105DC? How much?

uploaded 2 pics.
one full and 1 crop.

as for the technical details like fringing compared to 85 f1.4, i'm not sure if the pics could be compared this way.

anyway, here goes...

hmmmm...... blue fringing?

jeanie · 2nd December 2006

what's the diff bet fringing and ghosting?

wind30 · 2nd December 2006

what is ghosting? When I use the word "fringing" I use it as a layman term loh. Some color fringing at the sides.

I think there are many causes to fringing. Some can be lens, some can even be software related like my s3pro shows fringing with you use ACR to develop raw files.

Anyway, your fringing very little, much less than what my 85mm f1.4 shows. At the end of the day it is not that serious a problem. The f1.4 is really quite different from my old tamron 75mm f2.8.
