Thypoch TP-S21M-SR

The Simera 21mm f/1.4 is a manual focus Leica M prime with a 0.23m minimum focus distance and 1:2 magnification, landing in the 81st percentile for macro. Optical quality is well above average at the 78th percentile, but the overall score of 48.8 out of 100 reflects its specialist nature. No autofocus, no weather sealing, and a $100 price spread across US vendors.

The optical formula is where Thypoch put the work in. You get 13 elements in 11 groups, including 2 aspherical, 3 extra-low dispersion, and 3 high-refractive index elements. That's a lot of glass for a 21mm prime. The optical score lands at the 78th percentile, which translates to well above average in our database. Chromatic aberration and distortion are kept in check across the frame, which matters when you're shooting architecture or anything with straight lines near the edges.

The close focus performance is the real party trick. At 230mm minimum focus, you can get close enough for a 1:2 magnification ratio. That's genuinely impressive for a 21mm lens and it puts the macro score in the 81st percentile. You can fill the frame with a subject while still pulling in a huge amount of environment around it. The manual focus only design means no autofocus score to brag about, and the AF percentile of 14th reflects that. But for rangefinder shooters, manual focus is the point. The focus tab with tactile resistance at 0.7m is a thoughtful touch for street work.

Stacked against the competition, the Simera 21mm f/1.4 is a different animal entirely. The Sigma 18-50mm f/2.8 DC DN and Tamron 17-70mm f/2.8 are zoom lenses for APS-C mirrorless systems. They offer autofocus and versatility, but they can't touch the Simera's f/1.4 aperture or its 1:2 close focus. The Nikon Z 17-28mm f/2.8 is a full-frame ultra-wide zoom with autofocus and weather sealing, but it's heavier and can't get nearly as close. The Panasonic Leica 12-35mm f/2.8 is a Micro Four Thirds zoom, so it's playing in a completely different sensor size. The Sony 18-135mm f/3.5-5.6 OSS is a superzoom with optical stabilization, but it's slow at the wide end and nowhere near the Simera's optical quality. If you want autofocus and flexibility, buy one of those zooms. If you want a fast, close-focusing 21mm prime for a Leica M body, the Simera is basically in a class of one here.

Pricing is a bit of a moving target. US listings range from $899 to $999, a $100 spread across three vendors. Newegg has the most aggressive pricing at the lower end of that range, so if you're in the US, that's where we'd start looking. For a full-frame 21mm f/1.4 with this level of optical correction and close focus capability, $899 is a reasonable ask. But you're paying for the M-mount rangefinder experience, not autofocus or weather sealing. If you need a do-everything lens, this isn't the value play. If you want a creative ultra-wide prime with a close-up trick, the price per capability is solid.

The Thypoch Simera 21mm f/1.4 is a manual focus prime for Leica M shooters who want an ultra-wide with a serious close-up trick. The headline number is the 0.23m minimum focus distance, which gets you to a 1:2 magnification ratio. That's rare for a 21mm rangefinder lens and it lands in the 81st percentile for macro in our database. The optical score sits at the 78th percentile, which is strong for a third-party M-mount lens. But the overall score of 48.8 out of 100 tells you this is a specialist, not an all-rounder. It's built for a specific kind of shooter and it doesn't pretend otherwise.

At 427g with a 62mm filter thread, it's not a pancake but it won't wreck your neck either. The 14-blade aperture is a nice touch for bokeh lovers, though the bokeh score lands at a middle-of-the-pack 53rd percentile. The f/1.4 max aperture is bright, but the aperture percentile of 44th means it's not a standout in this category. The real story here is the combination of ultra-wide perspective and close focusing. That's a creative pairing you don't see every day.

Skip this if you need autofocus or weather sealing. The AF score is in the 14th percentile, which is expected for a manual focus M-mount lens but still a dealbreaker for many shooters. The travel score of 33.9 out of 100 is the weakest area, so if you want a grab-and-go lens for trips, this isn't it. The bokeh score of 53rd percentile is average, so if creamy background blur is your top priority, there are better options. And if you're not already invested in the Leica M system, the $899 to $999 price tag is a lot to pay for a lens with no autofocus and no weather sealing.

The Thypoch Simera 21mm f/1.4 is a lens with a very clear identity. It's for Leica M shooters who want an ultra-wide perspective with genuine close focus capability. The 1:2 magnification at 230mm is the standout feature, and the optical performance backs it up with a 78th percentile score. The f/1.4 aperture and 14-blade diaphragm give you creative control over depth of field and bokeh. But the overall score of 48.8 out of 100 is a reality check. This is not a versatile lens. No autofocus, no weather sealing, and a travel score of 33.9 out of 100. If you know exactly what you're getting into, it's a compelling option.
