Thypoch Simera 28mm f/1.4 28mm

The Thypoch Simera 28mm f/1.4 is a manual-focus prime with stunning bokeh and a fast aperture that puts it near the top of its class in those categories. It's beautifully built and a pleasure to handle, but sacrifices electronic contacts, leaving you without EXIF data and some focus assist features. At $319 to $547, it's a great value if you're fine with manual-only shooting and can put up with some flare and quality control quirks. If you need autofocus and tack-sharp corners, move along.

We ran the Simera through our usual tests, and the numbers back up its party trick: bokeh. The 14-blade diaphragm and f/1.4 aperture land in the 99th percentile for bokeh quality, meaning the out-of-focus areas are as smooth and creamy as anything we've tested. Wide open, you get dreamy subject isolation that 28mm f/2.8 lenses simply can't touch. Sharpness is good in the center, but corners soften up a bit until you stop down to f/4 or so. Our database puts its overall optical score in the 40th percentile, which tells you it's not a chart-topper. The rendering has a slightly warm bias and lower global contrast than modern AF primes, which some folks find charming and others find limiting.

In real-world use, the manual focus ring is a highlight. It's buttery smooth with just the right amount of resistance, and the crescent tab lets you zone-focus quickly. But here's the rub: without electronic contacts, your Z body won't record EXIF data like aperture or lens name, and focus-assist features like the green confirmation box are disabled. Focus peaking still works because it's purely contrast-based, so you can nail focus with that or magnification. Flare and ghosting are noticeable when a bright light source hits the front element, even with the hood on. It's not always a bad thing if you like the look, but for clean backlit shots you'll need to shield the lens carefully. Low-light performance, however, is excellent: the f/1.4 aperture soaks up light and keeps your ISO down when an f/2.8 lens would struggle.

Direct competitors for a manual 28mm f/1.4 on Nikon Z are scarce, but we can look at a few that sit in the same price neighborhood. The Viltrox Air 15mm f/1.7 is a fast wide-angle with autofocus, but it's made for Sony E-mount and offers a significantly wider field of view. If you're on Z, the Nikon Z 28mm f/2.8 is the obvious alternative: it's tiny, has full electronic integration, and nails focus instantly, but it gives up more than two stops of light and any real bokeh character. The Viltrox 16mm f/1.8 Z is a more serious rival at around $549; it's wider, autofocus, and nearly as fast, though it's larger and heavier.

The Sigma 10-18mm f/2.8 DC DN and Panasonic Leica DG Vario-Elmarit are zooms that serve different purposes entirely and aren't full-frame Z-mount lenses, so they don't really compete. For those who want an even faster manual prime, the Laowa 28mm f/1.2 exists but goes for about $1,100. The Simera sits in a unique spot where it's the cheapest way to get a 28mm f/1.4 on a Z body, and the trade-off is you're giving up modern conveniences for a beautifully damped focus ring and exceptional bokeh.

Pricing for the Simera 28mm f/1.4 is all over the map, ranging from $319 to $547 across different vendors. At the low end, that's an absolute steal for an f/1.4 prime with this build quality and bokeh chops. Even at the high end, it undercuts many AF primes while offering a stop or more of speed compared to the Nikon Z 28mm f/2.8, which hovers around $300. If you're willing to accept the manual-focus-only workflow, the Simera delivers an experience that feels far more expensive than its price tag.

We'd say the real value sweet spot is finding it for under $400. For that money, you get a lens that can create images with a look that the clinical budget options can't replicate. Just know that some of the savings come from the missing electronics, and you might need a few minutes to adjust the focus ring if your sample doesn't arrive perfectly calibrated at infinity. It's a lens where you're paying for character and tactility over autofocus convenience, and for the right person, that's a fantastic deal.

Thypoch's Simera 28mm f/1.4 is not just another fast prime. It's a deliberate throwback to the tactile, all-mechanical lenses that made photography feel like a craft. Clad in black aluminum and sporting a declickable aperture ring and a crescent-shaped focus tab, this manual-focus lens is built for Z-mount shooters who want to slow down and physically connect with their image-making. The f/1.4 aperture is rare at 28mm, and that alone will catch the eye of anyone who loves shallow depth of field or shoots in dim light.

We think this lens is for a specific kind of photographer. If you cut your teeth on vintage glass, or you're a street shooter who wants a compact, discreet setup with a characterful rendering, the Simera makes a lot of sense. Videographers will appreciate the smooth, click-free aperture changes. It's not a lens for everyone, though, and the lack of electronic contacts is a dealbreaker if you rely on autofocus confirmation or EXIF data. Our database ranks it as a standout for bokeh and aperture, but only middle-of-the-pack for overall optical performance, so expectations need to be calibrated.

What makes the Simera interesting, aside from the obvious speed, is how it blends old-school handling with modern glass. You get an ED element, two high-refractive index elements, and an aspherical element packed into 11 elements across 7 groups. The result is a lens that can produce beautifully soft backgrounds and sharp-enough subjects, without feeling antiseptic. It's a reminder that numbers aren't everything, and that a lens with personality can be more fun than a technically perfect one.

Landscape photographers who need sharpness from corner to corner at infinity should steer clear. The Simera's optical performance in that scenario is underwhelming, and you'll get far better results from the Nikon Z 28mm f/2.8 or a used Z 24-70mm f/4 S. If you rely on autofocus for events, sports, or fast-moving kids, the manual-only design will cost you shots, and you'd be happier with the Viltrox 16mm f/1.8 Z or any native AF prime. Videographers who want clickless aperture but also need continuous AF during a take will find this lens too limiting unless they're using a follow-focus rig and an assistant.

If you're the kind of shooter who values the process as much as the picture, the Thypoch Simera 28mm f/1.4 is a joy. It's built for deliberate, thoughtful photography where you have time to focus, compose, and appreciate the silky aperture clicks or lack thereof. Street photographers who want a discreet, fast 28mm with a signature look will find a lot to love, and videographers can leverage the declickable ring for smooth iris pulls.

On the flip side, if you need to grab focus on a moving subject or you're shooting events where missing a moment isn't an option, this lens will frustrate you. Landscape shooters should also look elsewhere; our scores show landscape performance in the bottom third, with softer corners and heavy flaring that don't suit sweeping scenic shots. For those folks, the autofocus Nikon Z 28mm f/2.8 or the wider Viltrox 16mm f/1.8 Z are smarter, more reliable choices.
