Moon over the Tango

The camera kept wanting to focus on the branches, so it was necessary to go to manual focus. Try as I might, I could not find a completely clear view. Next time I should probably go to manual exposure, too. Nikon D810 at 300mm.

Interesting, but I am not a fan of that bokeh quality. What lens is that?

Nikkor 75-300 AF @ 300mm. I would have to check the EXIF data to see what f/stop.

F/5.6 - wide open. Agree about the bokeh - spoils the image for me.

Often, bokeh in front of & behind focal plane are opposite, in terms of over- or under-correcting spherical aberration. The former looks bad. I suspect this lens' bokeh would not be so bad with OOF forms behind the plane of focus.

The portrait with "blown out" background and similar images are probably commoner than this, hence I suspect the bokeh is optimised behind the plane of focus deliberately, at the cost we see here.

Interesting about the front and rear focus bokeh. Didn’t know that. Learned something new!

Over-correction leads to OOF point highlights having a bright, sharp edge and being darker in the middle. Under-correction leads to a bright centre, fading at the edges. Correction leads to an even disc. The first is distracting, like the mirror lens bokeh.

I had a soft-focus zoom lens in which you could dial up under-correction at the focal plane, leading to beautiful SF effects. I dumped it eventually because the backgrounds looked so bad. I also did that with a Nikon 35mm f/2 AF lens before I'd even heard of bokeh, and use an older MF 35mm f/2.8 lens since.

I did think at first this was shot with a mirror lens.

Although i would agree on the quality of the bokeh I find it interesting that the eye is drawn right through by the sharper/lighter moon.

I think it may look better less saturated, and perhaps play about with the hue and intensity of the blues.
