OK, attached are two non-scientific snapshots of my office banana tree :)
I set the aperture at f/2.0 and I turned the focus ring to the closest distance of 1.1m.
Although the booklet accompanying the lens states clearly that the DC feature should be used according to the aperture set on the lens, I dismissed it and DCed to the maximum position. This is the first time I didn't follow the set rules  ;D
What I immediately noticed was that the focus distance changes as you rotate the DC ring.
In other words you can get closer with the DC ring at Rear and you need to move backwards if you rotate the DC ring to Front.
So even I had tried a scientific approach and put the camera on a tripod, I would have had difficulty performing the test at the closest distance from the subject :)

Another thing that I noticed was that I am steadily falling in love with this lens and it's creamy bokeh :)

The two photos attached depict the DC ring set to R and F at the nearest focus distance and at F/2.0.

So the DoF changes with the R and F setting even though f/2 does not change. Hmmm......
Jakov's first foto looks very Heligon-ish.

However, I'm still back there trying to figure out what are the sagittal and meridional planes of focus.  ;D

That's a beautiful dog Thomas and it shows off all the qualities of my next purchase :)

You buy a DOG? Wow. Does it have F-mount?

Now I read more and know you bought my brother's favorite lens.
You are out there. You and your camera. You can shoot or not shoot as you please. Discover the world, Your world. Show it to us. Or we might never see it.

It's a known fact that I am a 135 f2 DC slut.
But I use mine exclusively in studio for practical reasons. I often shoot at f2.
my copy back focussed and Nikon re-set it in combination with the body. I know of several copies that did BF rather than FF
Couldnt be more happy with what I get - though it could have been a tad shorter (or my studio a tad longer)

Erik, what are you waiting for? :)
Andrea, I am not sure that the depth of filed changes but the focusing distance to the subject. And as a consequence the depth of field changes the further away you are from the subject.
Almass, don't you know that we are all gone bananas :)
Børge, thank you!
Frank, I didn't buy your brother's favorite lens. I bought a brand new one:)
Elsa, I hope to become a 135 DC slut just like you are  ;D
John, thank you!

This might help or confuse. :) ...

I wonder what the "/Pumpkin/" reference is about?

Here is a lens test chart that might offer amusement when testing the DC feature of Nikon's DC lenses. Few seemed interested the first time around so few will probably be interested this time but the chart is FREE and one can print as many as needed. It can be spread out over a large area as compared to a focus chart that's a poster size so must be photographed at a close distance. I found this chart more useful than the USAF 1951 chart of years ago. Anyway here is the chart...

So the DoF changes with the R and F setting even though f/2 does not change. Hmmm......
When set to R the close focus limit reduces, and the background background blurs are more spread out and softer.
When set to F the close focus limit increases, and the background blurs are smaller with a sharply defined edge (foreground is soft instead).
That explains the difference in apparent DOF.

When set to R beyond the aperture setting, a soft focus effect are obtained, which is what we see here ... lovely results :)

David, thanks for the chart. I printed it out and I noticed that my sample auto focuses to the dot on the Df!

Thank you Roland! How can a banana not be lovely :)

Jakov, congrats on the lens.  I am happy to hear that it tests out spot on  :) .   Almost bought it several times but went with the 105 f2.  I keep thinking that Nikon will bring out a new version.  I could have used the extra 30mm on the recent trip.
Keep the images coming .
Bananas, I have about eight trees left (two varieties)  and they give me almost a constant supply.  I really like the colours of the 'food' pod.   I guess I could post images of the Pineapples but those take a heck of a long time to grow  ;) .

Thanks Tom. You are blessed to have an almost constant supply of bananas. My humble trees don't provide me with any  :-\
