Very nice Jack this instrument deserves too

One of my first attempts at abusing the 105mm. But I thought too much and shot at f5.6 :-(

Nice work Jack - every physics teacher should see this image.

roku-sen boke

roku-sen boke

inspiring image Jack, thanks! I do not know what roku-sen really means. Can you translate or circumscribe it ? The guitar strings view of front and back boke might be interesting to see for other portrait lenses, which some of the posters here may have. How would the Noct, the "Neo-Noct" Af-S 58mm f/1.4 , the AF-S 105mm f/1.4, the Sigma Art 105mm f/1.4 and the Sigma Art 135mm f/1.8 or the Z Plena 135mm f/1.8 show their boke along the strings ?

my quick boke test for the AF-S 105mm f/1.4 at f/1.4 MFD. I used a black mouse mat for improved uniformity of background. I do not have the other Portrait lenses, except a AF 135mm f/2 DC. I would be curious to see your quick string boke tests.
The AF-S 105mm f/1.4 has a boke close to neutral with no outlining of the front boke. In the near field back boke it shows a distribution with center emphasis as the DC lenses. From Oelund's reports, I would expect the Neo-Noct behaves similarly, probably with more emphasis on the near field boke.
