Thypoch Simera 75mm F1.4 75mm

The f/1.4 aperture and 94th percentile bokeh are the stars here, making this a fantastic portrait lens for Leica M shooters. But the overall optical quality is in the 20th percentile, and landscape performance is a dismal 16.1 out of 100. It's a one-trick pony with a very good trick, just don't expect it to do anything else well.

Wide open at f/1.4, this lens is all about that bokeh. The 16 rounded aperture blades do serious work here, keeping specular highlights smooth and circular even when stopped down a bit. In our database, the bokeh quality is a standout, easily beating most modern autofocus lenses. The 75mm focal length on a full-frame Leica body gives you a flattering perspective for portraits, and the fast aperture lets you shoot in dim light without cranking the ISO. Sharpness in the center is solid for a fast prime, but don't expect corner-to-corner perfection. The optical score in the 20th percentile tells the real story: this lens prioritizes character over clinical sharpness.

Manual focus is the only option here, and the focus ring has a nice, damped feel that's typical of quality M-mount glass. The lack of autofocus puts it right in the middle of the pack at the 54th percentile, which is fine for a rangefinder lens but will feel slow if you're used to modern mirrorless systems. There's no stabilization either, sitting in the 37th percentile, so you'll need steady hands or faster shutter speeds, especially in low light.

Stacked against the Sigma Contemporary 18-50mm f/2.8 DC DN or the Tamron 17-70mm f/2.8 Di III-A VC RXD, the Thypoch feels like a niche tool from another era. Those zooms offer autofocus, stabilization, and zoom flexibility for similar or less money, but they can't touch the f/1.4 aperture or the bokeh quality. The Nikon Z 17-28mm f/2.8 and Sony E 18-135mm f/3.5-5.6 OSS are even more versatile, but again, they're slower and won't give you that creamy background separation. The Panasonic Leica DG Vario-Elmarit 12-35mm f/2.8 is a different beast entirely for Micro Four Thirds. If you're on a Leica M body and want a dedicated portrait lens with character, the Thypoch makes sense. For everyone else, these competitors are more practical daily drivers.

At $849, the Thypoch Simera 75mm F1.4 is priced like a mid-range portrait lens, but you're paying almost entirely for that f/1.4 aperture and the bokeh. For a Leica M-mount lens, this is actually on the affordable side compared to first-party glass from Leica or even Voigtlander. But you're giving up autofocus, stabilization, and strong optical performance across the frame. If you only care about subject isolation and that classic rangefinder shooting experience, the price per unit of bokeh is solid. If you need a more versatile telephoto, your money goes further elsewhere.

The Thypoch Simera 75mm F1.4 is a portrait specialist that nails the fundamentals of subject isolation. Its f/1.4 aperture sits in the 96th percentile for this category, and the bokeh quality is among the best we've seen, landing in the 94th percentile. That combination means you get dreamy, creamy backgrounds that make your subject pop, and the 16-blade aperture keeps those out-of-focus highlights perfectly round. It's a manual focus lens built for Leica M-mount rangefinders, so you're signing up for a deliberate, tactile shooting experience.

But this lens is a one-trick pony, and it knows it. Our scoring puts its total at 43.6 out of 100, dragged down by a landscape score of just 16.1. There's no autofocus, no stabilization, and the optical quality overall lands in the 20th percentile. If you're not shooting portraits or close-up details, this lens will frustrate you. The 0.6m minimum focus distance is a nice touch for detail shots, but don't confuse this with a true macro lens despite its strong 95th percentile macro ranking.

If you shoot anything other than portraits or close-up details, skip this lens. The landscape score of 16.1 is a dealbreaker for scenic work, and the 20th percentile optical quality means you won't get the sharpness across the frame that modern sensors demand. Anyone who needs autofocus or stabilization should also look elsewhere, as this lens offers neither. It's a specialized tool for Leica M shooters who value bokeh above all else, not a general-purpose telephoto.

The Thypoch Simera 75mm F1.4 is a portrait purist's lens. It delivers best-in-class bokeh and a fast aperture that makes your subjects stand out, and the manual focus experience is genuinely enjoyable on a Leica rangefinder. But the weak optical score and abysmal landscape performance mean this is not a general-purpose lens. Buy it for the bokeh and the build, but know you're sacrificing versatility and sharpness across the frame. If you shoot portraits and close-ups on an M-mount body, this is a compelling option. If you need a lens that does it all, look elsewhere.
