Camera f-stops are based on the square root of 2. To go one stop slower, you multiply by 1.4 (the sqrt of 2, rounded off). To go one stop faster, you divide by 1.4.

Common “fast” 50mm lens is f/1.4. One stop faster=1.4 / 1.4=f/1.0. Going one more stop faster=1.0 / 1.4=f/0.7.

So, f/0.95 is so close to f/1 to be considered as f/1.

Why are fstops based on the square root of 2? Because to double the area of a circle you multiply it by the sqrt(2). When applied to the ratio of 1:f, you reverse the usage of division/multiplication.

1x1.4=1.4, 1.4x1.4=2, 2x1.4=2.8, 2.8x1.4=4, 4x1.4=5.6, 5.6x1.4=8, 8x1.4=11, 11x1.4=16... is this sequence starting to look familiar?

Will be bought by some professionals and by the very rich and trust fund babies. May be a good investment to buy one and keep it for 10-15 years and sell it for much more than it cost. I would guess that it will be a huge hunk of glass that very few will lug around. Probably will stay in the studio or home for most that but them. How many night photographers can afford this monster?

The Leitz counterpart is $11,300, or $15,900 for the Cine model, making the Nikkor a real bargain. Yes, and people do buy them. Many more photographers rent them, though.


Yeah. VCine is really the main use of lenses with
zero usable DoF. The motion of the crazy-thin
focus plane as it moves thru the subject field is
a mean of steering the eyes of the audience .

OTOH, for still images, the fixed, unmoving, and
uselessly thin plane of focus is self defeating.

There's nothing magic about an f-number lower
than 1 ... it's just a mental milestone. One can
quite easily experience that same lack of DoF for
waaaaay under $6K. The lens in question has a
60mm aperture size. My 105/1.8 with its 58mm
aperture can be yours for waaaay less than $6K.
I once had a 135/2.0 ... thaz a 67mm aperture.
What do you think happens to the DoF of that
58/0.95 when you put it on a 2X TC ? Nothing.
It stays the same, altho the lens is has become
an 116mm f/2.0 .... hardly an exotic spec, fast
but nothing "drool-worthy".

It's about the correction for night shooting, not necessarily about the speed. The aperture will give insane bokeh. The old 58mm f1.2 Noct is highly coveted, with good examples going for $4000.

I would think people spending other peoples money will not have a problem with the price. (Universities and government offices).

We used something called Painting with Light. BTW, I have a Voightlander 50mm F 1.1. Norton. Great lens. I sold the Leica lens and bought my wife a Rolex. I should have kept the Leica, she left me.

Photography Websites are reporting the price of the upcoming Nikkor 58mm f0.95 NOCT Z-mount lens at $6000-8000.

I wonder who is going to buy that lens and how many they will sell at that price?


The slogan on the box under the name Nikon should be, "There's a sucker born every minute. Now you're one of them."

I'm holding out for the next big development, a lens with a negative f#. It will allow me to shoot in environments even darker than total darkness. >Alan

I laugh because f0.95 is old 60s technology for Canon.
Nikon is making a manual focus copy of what Canon did decades ago.
Oh well.

Not at all, not at all. First, the Canon is 50mm, not 58mm, which is already a big difference at f0.95. As the owner of a Canon f0.95, I can say that it is a wonderful lens, but one full of optical aberrations and none too sharp wide open. If Nikon can make a f0.95 lens that performs as well as the old f1.2 Noct Nikkor it will be a stellar achievement in the art of lens design, and I highly applaud Nikon for their decision to make a lens in the tradition of old wild Nikkors like the 6mm f2.8 and the 1200-1700mm zoom.

Most amateurs will not have the money or the skill to own one or use it to its full potential, but that is no reason to put down a beautiful lens that extends the possibilities of the photographic art. Bravo Nikon!

Just to let you kit lens users know: in the world of professional lenses, especially for cine, this is cheap. Good cine lenses can easily cost $50K. The ancient Canon f0.95 goes for $3K in good condition.
