Nice and relaxed shot John. That background sure seems smooth and doesn't have the double lines and nervousness that most of the Nikon's 55/1.2 or 50/1.2 or 50/1.4 often have.

Thanks Peter.

Yes, that did surprise me.  I have the 50/1.4 S-Auto but that has indeed a nervous bokeh. The 5.8cm f/1.4  is far from perfect, field distortion, weak corners but center, DOF and bokeh are great.  It is also part of the Nikkor Thousand and One Tales.

"In terms of the balance between aberrations, this lens was typical of the early Gauss-type lenses. The addition of a convex lens to the front group was superbly effective in correcting spherical aberration. Longitudinal (axial) chromatic aberration and lateral chromatic aberration were both minimized and the astigmatism correction was excellent."   http://www.nikkor.com/story/0040/

What do you mean with Coma, Fons?

The copy i used on Df was quite temperamental, colour aberations, uneven exposures so high failrate, though i managed to get some good ones also.

The Nikkor 5.8cm/1.4 was the first f/1.4 lens for the Nikon F-mouth.   
Very smooth rendering, sweeter than the 55/1.2
Some tests with the Fuji S5

Also some kind of Noct?

You must have had a lemon, I think. Mine is mint as if it never was used, late serial number,  Ai'd, perfect with exposure, very minor chromatic aberrations and a very low fail-rate for a f/1.4 lens wide open.

[John Geerts]

Also some kind of Noct?

Looks like it, although I never used a Noct.  "The focal length of 5.8cm represented a trade-off between the decline in performance caused by ensuring the necessary back focus and the need to set a focal length that still fell within the range that would allow the lens to be termed a standard lens. For a short telephoto lens, however, this was a fairly workable focal length. The Noct-Nikkor lens, which was released later with a focal length of 58mm, emulated the 5.8cm f/1.4 in this regard."  http://www.nikkor.com/story/0040/ 

I compared the bokeh of the lens briefly with the 55/1.2 Ai and 50/1.2 Ai-S and the the 5.8/1.4 is softer and creamier with a more gradual transition.

Did you get very dirty???

I saw it on the internet

Not so nice weather today. 

The '1961'-lens on the Df.

Wonderful image Akira, I can imagine the music

Thanks, Armando.  Her music is really touching.

Nice intimate shot, Fons!

Thank you John.

Not at all. The dust went all with the wind to the other direction.
Was a nice blast, within 3s two blasts, within 10s everything was down. The D4 was the right tool to catch it. Unfortunately there was this sign in front of my view, but that was the best place I could get.
