This review is cross-posted on both the Nikon and Canon boards, since the Nikon Z and Canon RF versions of the Voigtlander 35mm f/1.4 Nokton share the same optical design, with only minor adjustments made to accommodate the different sensor stack thicknesses between mounts.
Is the Voigtlander 35mm f/1.4 Nokton Z-mount the perfect match for the Nikon Zf?

There is a certain kind of lens that doesn't try to win charts, it tries to win you over. This new Voigtlander 35mm f/1.4 Nokton for Nikon Z-mount lands in that camp, and paired with the Nikon Zf and its 24MP sensor, it just feels right.
On paper, it almost reads like a contradiction. A very compact 35mm with a fast f/1.4 aperture, modern electronic contacts, full EXIF support, in-body stabilization compatibility, and even focus confirmation. That's all very 2026. But the moment you start shooting, it is clear this lens is chasing something else entirely. Cosina deliberately leaves some aberrations undercorrected, not because they couldn't fix them, but because they chose not to. The goal isn't clinical perfection. It's character, drawing style, and the way an image feels.
The optical design takes inspiration from a classic symmetrical approach, updated with modern glass and coatings. A high refractive index element was added, taming excessive glow while still delivering that fast aperture look. At its core, this is a double Gauss, near-symmetrical design with 6 groups and 8 elements. Cosina didn't reinvent anything here, they refined a proven formula.

The aperture uses a 10 blade straight design, typical of many Cosina lenses. You won't get perfectly round highlights when stopped down, but you will get well-defined sunstars that a lot of people, myself included, appreciate.
Filter size stays at 58mm, same as the E-mount version. It keeps the lens compact and practical, especially if you already have filters in that size.
One thing that genuinely surprised me is that Cosina managed to make the Voigtlander 35mm f/1.4 Nokton Z-mount version lighter than the E-mount. The Z version comes in at 248 grams versus 262 grams for E-mount. It is not a big difference in hand, but it goes against the usual trend where lenses get heavier as mounts get larger. Even better, the minimum focus distance is now 0.27m instead of 0.3 meters. It's a small change, but it gives you just a bit more flexibility up close, and in real shooting, that does matter.

I've spent a lot of time with the E-mount version over the years, and I know the M-mount version well too. The DNA here clearly traces back to the Leica 35mm f/1.4 Summilux pre-ASPH, one of the most iconic character lenses ever made. That lineage shows. This isn't about corner to corner perfection at f/1.4. It's about how the lens draws, how it transitions, and how it renders a scene in a way that feels intentional rather than a modern optimized look.

Add in a beautifully machined all metal helicoid with just the right damping and crisp, well-defined aperture clicks, and the shooting experience really comes together. This review copy is perfectly centered.
Manual focus here is a pleasure and honestly, one of the things I've been enjoying most using the Nikon system again is the focus confirmation. It changes the whole experience. It almost feels like shooting a rangefinder, except instead of a patch, you get that clean confirmation signal while composing. You stay in the moment, you stay connected to your composition.
In a world chasing speed and sharpness above everything else, this lens goes the other way. That is exactly why it stands out.

Infinity Resolution and Contrast on Nikon ZF (24MP)
It's easy to get the wrong impression from this lens if you don't separate how it behaves wide open versus stopped down.
Wide open at f/1.4, the Voigtlander 35mm Nokton is not trying to be a high-resolution, high-contrast performer across the frame. Contrast is lower, and fine detail, especially toward the corners, takes a hit. That's mostly due to residual spherical aberration, along with some astigmatism and a bit of field curvature. The center holds up reasonably well, but away from it, things get softer and a bit less defined.
Once you start stopping down, the lens begins to clean up quickly. At f/2 and f/2.8, you can already see a noticeable improvement as spherical aberration gets under control. By f/4, the lens really snaps into place. That's where you see a clear jump in high-frequency detail and contrast across the entire frame, center, mid-zone, and corners. I would call f/4 the sweet spot.
For the corners to fully come together, you will want to be around f/5.6 or f/8. At those apertures, performance is strong and even across the frame. Field curvature also becomes much less of a factor since it's completely masked, which helps give a more consistent result edge to edge.
None of this is surprising when you consider the design. This lens traces back to the classic double Gauss formula used in the Leica 35mm f/1.4 Summilux pre-ASPH, later refined in the Voigtlander 35mm f/1.4 Nokton VM. What we have here is essentially that same Voigtlander design, tweaked for the Nikon sensor stack. So this behavior is expected. If anything, I'd say this Z-mount version performs slightly better in the corners compared to the VM version.
In real use, it comes down to intent. Shoot it wide open and you get a softer, more organic look with rendering many will appreciate. Stop it down to f/2.8 and it sharpens up nicely, and by f/5.6 or f/8 it becomes a very solid performer for landscapes with good consistency across the frame.
Distance: Infinity
Focus: Center - Best of three shots at maximum magnification
White Balance: Daylight
Both lenses are perfectly centered, as verified with my decentering test.
Software used: Lightroom with FM Default Landscape Sharpening; all other settings are at default.
PS: Vignetting, Chromatic Aberration (CA), and distortion were not corrected either in post-processing or in-camera.

This is the lens I have been waiting for to really solidify my ZF as my main camera. I've used it on film leica M for a few years and its rendering remains to be a total sweet spot for me. Really looking forward to your review Fred - I know how magical it can be, and with the focus confirm capability on the ZF I feel there's finally a manual focus system to rival the M-mount rangefinder manual focussing capability.
Interestingly this Z mount iteration seems to be more consistent for sharpness across the frame than what I'm used to from the M-mount version.

it's a comment. Sorry for the confusion.

I see no reason to swap an excellent lens for a compromise-lens with uncorrected aberrations people call "character" .
This 35 Nokton is smaller and faster for sure. It would be interesting to compare the VM 35/1.4 Nokton on Leica vs the 35/1.4 Z on Zf.

I agree that a swap does not seem logical, but speaking for myself I can see this Nokton as an addition because it can deliver pictures that the APO can’t. And vice versa. I see myself using this lens wide open or at f2.

I am sorry for not understanding. Not a swap I would make, but it is interesting that people are thinking of doing so.

I don't mean to insult your baby. The APO is wonderful but suits a purpose that isn't mine. What I want is chipped Z Ultron and this gets closer. This one might be good enough.
Better or worse, most of the Noktons are clones of a particular (older or newer) Summilux and the APOs, Summicrons. Two different looks for nearly 70 years.

I use 28nok & 50apo&nok. 35 is an experiment, going up the middle. Tried a little adapted 35 Sumaron and found it "tight", but I kinda liked it so I tried the 35APO. The APO is not great living on the Zf all day walking around the city and I don't need NASA satellite IQ. It's probably fine on a modern grip camera. From what is posted here, it looks like the IQ of this one is fine, in a reasonable size for the Zf.

The Voigtlander 35mm f/1.4 Nokton Z-mount behaves very similarly to the original VM version when it comes to field curvature (FC).
Because the FC pattern remains consistent with the M-mount version, this suggests that Cosina adjusted the optical design to account for the Nikon sensor stack thickness while preserving the same rendering characteristics.
As shown in the animation below, the FC changes with focus distance, curving outward up close, flattening at mid distance, and turning inward at longer distances.
The GIF illustrates the focus plane moving from close distance to infinity in several steps. At f/1.4, the depth of field is shallow enough to clearly reveal the shape of the FC at each distance, which makes these transitions easy to see.
