Thypoch Simera TP-S75M-BLK 75mm

With bokeh in the 99th percentile of all lenses we've tested, the Thypoch Simera 75mm f/1.4 is an absolute background-blur champion. It gives you f/1.4 brightness, a 16-blade aperture, and a close 0.61m focus in a 372g manual-focus package for Leica M. Sharpness is mid-pack and there's no AF or sealing, but for dreamy portraits the numbers speak for themselves.

The star here is bokeh, period. That 99th percentile ranking means the rendering is as good as it gets, and the 16-blade aperture helps keep out-of-focus highlights round and pleasing even when stopped down a bit. The f/1.4 maximum aperture gives you bright viewfinder images and that dreamy separation between subject and background, and our database puts its light-gathering ability behind only a handful of super-fast primes. Chromatic aberration control is good thanks to two ED elements, but the overall optical score landed right at the 51st percentile, so sharpness across the frame is competitive but not class-leading. You'll get crisp results in the center, though corners might not satisfy pixel-peepers at wide apertures.

The manual focus action is smooth and well-damped, but all-manual operation puts its autofocus rank at a low 14th percentile, which is no surprise but worth stating if you're used to modern mirrorless lenses. At 372g, it balances nicely on an M body without making the kit front-heavy. Minimum focus of 0.61m and 1:2 magnification let you get close, but our macro score of 46th percentile reminds you this isn't a macro lens; it's a portrait tool that happens to focus a little closer than typical 75mm primes. There's no stabilization, so keep your shutter speeds up in low light or rely on good technique.

The competitor list is full of zooms like the Canon RF 28-70mm f/2.8 IS STM and Nikon Z 18-140mm f/3.5-6.3 VR, which shows how niche the Thypoch really is. Those lenses offer autofocus, stabilization, and versatile focal ranges, but they can't touch f/1.4 brightness or the manual focus feel of a dedicated Leica M lens. If you're cross-shopping a 75mm portrait prime, something like a Voigtlander Nokton 75mm f/1.5 might come up, but the Simera's bokeh rank suggests it's a strong contender against pricier options. The Viltrox AF 56mm f/1.7 is autofocus and cheaper but built for APS-C, so it's not a direct rival. For pure image character on a rangefinder, the Thypoch stands alone among these listed competitors.

Pinning down a fair price is messy because retailers list this lens anywhere from $849 all the way up to an absurd $116,370, which is almost certainly a joke or a data glitch. Assuming the $849 figure is real, you're getting a well-built f/1.4 prime with chart-topping bokeh for less than many comparable Leica M lenses. At that price, the value proposition looks strong for portrait shooters who prefer manual focus. Just double-check the store and maybe laugh at the $100K listings before you click buy.

The Thypoch Simera 75mm f/1.4 lands with bokeh that sits in the 99th percentile of all lenses we've tested, putting it squarely among the best for creamy, smooth backgrounds. The fast f/1.4 aperture (94th percentile) lets in serious light and gives you that shallow depth of field Leica shooters chase, all in a compact 372g metal package with a 58mm filter thread. But the numbers also show a trade-off: this is a manual focus lens only, no weather sealing, and optical sharpness is middle of the pack at the 51st percentile. If you want autofocus or all-weather confidence, the spec sheet already tells you to look elsewhere.

Still, the lens brings a 16-blade diaphragm and a close 0.61m minimum focus for 1:2 magnification, not true macro but handy for detail shots. The build quality feels solid, scoring in the 62nd percentile, not tank-like but well put together. For portrait photographers who value character and blur over absolute edge-to-edge sharpness, this Simera makes a compelling argument, provided you're comfortable focusing by hand on a Leica M body.

Skip this lens if you need autofocus (AF percentile is a dismal 14th) or anything resembling weather resistance. The optical sharpness is average, so if you chase corner-to-corner detail at every aperture or shoot architecture, look for a lens with a higher optical ranking. Travel photographers will find the 32/100 travel score a realistic warning: this is a specialist tool, not an all-rounder, and lugging a manual prime with no zoom flexibility will slow you down.

If you shoot a Leica M and your priority is gorgeous background blur, the Thypoch Simera 75mm f/1.4 deserves a spot near the top of your list. Its 99th percentile bokeh and fast aperture deliver the kind of dreamy portraits that make manual focusing feel worth the effort. Just know that optical sharpness is only average, there's no weather sealing, and you'll need to avoid those vendors trying to charge five figures. For a dedicated portrait lens with real character, it's a data-backed gem.
