What exactly is the 10% hit rate? Are those the photo that were in focus? There's a lot of digital noise because the ISO is at 16,000. The shutter speed was 1/640 second which is fast enough to get a photo that is free of camera shake. The OP is already using an f/1.2 lens. If your D850 is hunting for focus in the low light, you will need to go to a Z9.
When it comes to low-light performance, the D850 is without a doubt one of the best cameras on the market. Thanks to its -4 EV low-light sensitivity
When considering low-light autofocus, the Z9 is Nikon's best camera yet. The camera can focus down to -8.5 EV with the newly-branded Starlight View mode. Without that mode, the camera is rated to focus down to -6.5 EV.

That's actually the lens I used 🤪 but a bit crazy in the circumstances.
I shot a fashion show a few weeks back. It was a "club" themed shoot so the light was low and of course no static subjects. Anyway, I used the 50mm f1.2 with natural light so my hit rate was going to be low for obvious reasons (10%). I'm going to try a few AF lenses in the 45mm to 58mm range to see if it is possible to get a less disappointing hit rate.
TIA

When you said the hit rate is 10%, are you referring to autofocus accuracy? If so, you may have to go to a Z9 for better low light autofocus capabilty.
The D850 autofocus is rated to -4EV
The Z9 is can focus down to -8.5 EV with the Starlight View mode
Without that mode, the camera is rated to autofocus down to -6.5 EV.

Out of context. I'm responding to a specific post and commenting that you should get better Bokeh with a wider aperture lens. Just another reason to own a 1.2. Best of luck.
I understand.

It's called Bokeh!
Read the OP's third post on page one. He's not talking about bokeh. He's concerned about the 10% hit rate. I saw in the photo's that the ISO was 16000. Bringing the ISO down. The 3.5 stop vibration compensation of the Tamron 45mm would allow shooting at slower shutter speeds. He could reduce the ISO and improve the quality. Go back to his previous posts. Where is he concerned about bokeh?

Hi all.
I'm looking for a fast AF lens in the 50mm range, say 40mm to 58mm. I was looking at Nikon's 50mm f1.4 but would love any other mentions.
TIA

You shot the photo at f/1.2. An f/1.4 lens won't help out.

The aperture was f/1.2 and the ISO was 16000. The max aperture on the Tamron 45mm is f/1.8 which is one f-stop slower but you gain 3.5 stops in hand holding ability because of the vibration compensation. You could reduce the ISO and get lower digital noise.

I use the Tamron cuz it’s the only normal lens with VR. In many situations, “fast” and VR belong together.
Aside from having VR, it’s one of those distagon type “Super Normals”. So it’s a bit oversized, but is smaller than Zeiss, Sigma, etc, of the same type. This is cuz it’s 45mm not 55, and it’s f/1.8, not 1.4.

I also have the Tamron 45mm f/1.8. I use it on my Nikon D750. It has pro build quality with a metal lens barrel and has weather sealing. The vibration compensation really helps.

This is a good video that shows the effects of volume anamorphosis. This is an older video that's demonstrating the first version of DxO Viewpoint. The latest is Viewpoint3.

It was done on page 5 of this thread. DxO ViewPoint3 was used.

UHH members gave great advice already. There's a couple of other things that could be considered. The Z6II has better dynamic range (almost one stop better) starting at ISO 400 and up. It also has slightly better signal to noise ratio.

I took that photo into DxO ViewPoint3 and used the volume deformation feature. The lady on the left looks more normal now.

Volume anamorphosis. Only software I know of that can fix it is DXO Photolab or Viewpoint 3. Wide lenses also display extension distortion, which, when used for portraits, makes everyone look like they have a "horse face" when the camera -subject distance is diminished to do a head shot. That distortion happens exactly in the center of the lens.

Gene51 is right on the money. I also use DxO PhotoLab and Viewpoint3. The DxO website has examples of volume anamorphosis.Feb 14, 2022 14:03:23 #

It's actually more than volume deformation. The picture was also taken from below and as a result there is also perspective distortion with converging verticals. Both of those issues can be addressed in DxO's products. However whether they should be for this spontaneous snapshot of an event is another question.
That's right. I have a photo at home that has both volume deformation and converging verticals. DxO ViewPoint3 corrected both. I will post them later today.Feb 14, 2022 13:35:11 #
It's volume deformation. It's also called volume anamorphosis. The woman on the left is stretched horizontally because of that. I use DxO Labs ViewPoint 3 to correct it. There's a lot of information about it on the DxO Labs website. I will post a before and after photo later where I used the volume deformation tool in ViewPoint3 to correct it.

You can see the difference between when VR is on and when it's off when looking through the viewfinder but it's subtle. Some lenses make a slight sound when VR is actively working. My Nikon 70-300mm AF-S VR lens sounds like running water when the VR is working. How did you determine that the VR is not working? Check the switch positions on the lens.
