Nice bookeh or colour bleeding?

[rui]

Hello!
I bought a scratched rigid Summicron about an year ago and sent the front element to Arax for recoating. It looks great but the focus was a bit off, so I had it adjusted. Now the focus is perfectly accurate and it takes nice pictures, but it bugs me to think that the repolishing and recoating may have changed other optical properties of the lens... So, I'm hesitating if I should keep it or sell it to buy another rigid (or DR) with no scratches. :bang:

For instance, in the attached pic (you can see it bigger here), is it first class bookeh or some colour bleeding that I see? 😕

Well... I'd like to know what you might think about it. Thanks! (btw, this is my first thread in here...)

A little of both it looks like. It appears that your red channel is hitting the wall, so it's turning pink in places.

A lot of saturation-maybe a post processing thing as opposed to lens problem.

Looks OK to me, tricky background, strong contrast subject/scan.

Take a test shot of tree leaves in the background, to check if the
lens has coma.

Best,

Roland.

Perhaps you can define "color bleeding." It is not an optical or photographic term.

The film is Velvia 50, which might explain some of the saturation...

To explain what I mean by colour bleeding, I cropped at full resolution a part of the picture. I have the idea that the warm colours tend to be more out of focus than the cool colours. It looks like if the reds "bleed" into the surrounding colours, so "bleeding" is just a way to try and describe this effect... What do you think? 🙄

What you are describing in the reason why APO coatings were made. This was to try to get all colour wave lengths to focus at the same point. Fuji film is makes greens very vibrant and the opposite of green is red. Your problem may be a combination of non APO coatings and very colour biased film. Buy some tri-x and dont worry about colour 🙂 Andrew.

I'd say that is irrelevant, as long as you cand ecide if you like the shot, or not.
If you like the results, keep it. If you don't like the results, don't keep it.
It is that simple.

[I like it.]

What do i think? I think you want to push us into pixel peeping🙂
I don't agree with the more in-focus observation.

It is simply effects caused by focus/depth of field. What you did to the lens would not be the cause.

word. dunno about color bleeding but it hurts my eyes. my nikon 50 1.8 at times makes hurtfull bokeh like that.

bokeh looks harsh like my cv 40mm wide open....😛
