Thypoch Simera Simera 28mm f/1.4 28mm

The Thypoch Simera 28mm f/1.4 delivers dreamy bokeh (top 2% in our database) and cinematic rendering in a compact manual focus package. It's a joy to use on M-mount bodies, but you'll give up autofocus, EXIF data, and weather sealing. At sale prices around $400, it's a fantastic deal for character-first photographers.

The Simera is all about that bokeh. With 14 aperture blades, out-of-focus areas are buttery smooth and highlights stay round, giving portraits and close-ups a genuine 3D pop. Center sharpness is strong at f/1.4, but the corners need stopping down to f/2.8 before they catch up. Chromatic aberration is well controlled, and the floating element design keeps close-focus performance respectable. Our optical score lands at a middling 62nd percentile, which makes sense—this lens prioritizes rendering over absolute sharpness. The spec sheet mentions stabilization, but we couldn't confirm any meaningful effect; honestly, f/1.4 handles low light so well you probably won't miss it.

The Simera doesn't really compete with the AF zooms in our database like the Canon RF 28-70mm f/2.8 or the Tamron 17-70mm f/2.8—those are aimed at a completely different audience. For M‑mount shooters, the closest rival is the Voigtländer Ultron 28mm f/2. That lens is slower but sharper across the entire frame and includes electronic contacts for EXIF data. The Simera gives you a full extra stop of light and that unique 14-blade bokeh, but trades away modern conveniences. On Sony E-mount, the Viltrox Air 15mm f/1.7 offers a fast wide prime with autofocus, but it's not a 28mm and feels very different in hand. The Simera is for the analog-minded photographer who values rendering and tactile experience over specs.

Pricing for the Simera is unpredictable. We've seen it listed anywhere from $399 to $817 across different dealers. At the low end, it's a borderline steal for the build quality and unique rendering. Up near $800, it's a tougher sell—used Leica or Voigtländer glass with electronic contacts starts to look tempting. If you shop around and catch a sale, targeting the $400-$500 range makes this lens feel like a real find. No single retailer consistently has the best price, so keep an eye on stock and don't overpay.

The Thypoch Simera 28mm f/1.4 is a manual focus prime built for Leica M shooters who care more about character than tech specs. It pairs a fast, bright f/1.4 aperture with a complex 14-blade diaphragm, churning out some of the creamiest bokeh we've tested in this focal length—seriously, it landed in the 98th percentile of our database. All that glass is packed into a compact 330g body with a vintage-inspired focus tab and a declickable aperture ring that film shooters and hybrid video folks will immediately appreciate.

But there are trade-offs. This lens has zero electronic contacts, so your camera won't record aperture or lens info in EXIF, and focus-peaking is the only assistance you'll get. Weather sealing is absent, and corners at f/1.4 are soft enough to remind you this isn't a clinical optic. Still, if you're after a 28mm with real personality and a price that varies wildly (we've seen it as low as $399), it's a compelling choice.

Skip this lens if you need autofocus for fast street or event work, because the manual-only operation will slow you down. If weather resistance is critical, look elsewhere—the Simera has no sealing against dust or moisture. Also, rangefinder photographers who prize full EXIF data and factory 6-bit coding should consider Voigtländer or Leica alternatives with electronic contacts instead.

If you own a Leica M body and crave a fast 28mm with gorgeous bokeh and a vintage soul, the Thypoch Simera is a wonderful lens. It's not for everyone—you'll miss autofocus and weather protection—but for deliberate, creative work, it's a gem. Especially if you can snag it for around $400, it's hard to pass up.
