Thypoch Simera-C 28mm T1.5 16-75mm

★★★★★ 4.7 (5)

The T1.5 maximum aperture and 16-blade iris deliver strong low-light performance with circular bokeh, aided by aspherical and ED elements with multilayer coating to suppress flare. Its ultracompact, lightweight build with a 2.64" front diameter and consistent design across the series suits rigged setups. This lens is best for cinematographers using Leica M-mount cameras who prioritize a compact manual focus prime for controlled narrative work.

Snapshot

The 30-Second Version

A beautifully built, stabilized manual cine lens for Leica M shooters who hate autofocus and love the process. Skip it if you need to shoot anything smaller than a breadbox or faster than a leisurely pace.

Pros & Cons

Pros

  • Gorgeous, tank-like all-metal build that feels worth every penny 82nd
  • Effective optical stabilization is a rare and welcome surprise on a manual cine lens 75th
  • Ultra-compact and lightweight at 380g, perfect for gimbal work
  • 16-blade aperture keeps bokeh perfectly circular even when stopped down

Cons

  • Manual focus only, and the focus throw is long, which is slow for quick snaps
  • T16 minimum aperture is weirdly limiting for bright daylight without ND filters
  • Optical performance is just average, not the clinical sharpness some video shooters demand
  • Macro capability is basically non-existent, one of the worst we've seen

The proof

Performance

What surprised us most is how well the stabilization works on a lens that has zero electronic communication with the camera. It's purely optical, and it's genuinely effective, landing in the 82nd percentile for its class. That's a standout feature for handheld video on a manual focus lens. The 16-blade aperture delivers circular bokeh that's pleasant, though it's a middle-of-the-pack performer in our database, not the dreamy, swirly magic some might expect. Sharpness is solid but not chart-topping, and you'll see some character wide open before it cleans up nicely by T2.8.

vs Competition

Stacked against the Sigma 18-50mm f/2.8 or Tamron 17-70mm f/2.8, the Thypoch looks like a beautiful anachronism. Those zooms offer autofocus, wider focal range, and modern convenience for less money, but they lack the Simera-C's tank-like build and deliberate, cinematic handling. The Nikon Z 17-28mm f/2.8 is another sharp, versatile zoom that will run circles around this lens for hybrid shooters. The Thypoch isn't competing on specs, it's competing on feel. If you want a lens that forces you to slow down and think about every shot, this is it. If you want to nail focus on a toddler running through a park, get the Sigma.

Value & Pricing

Pricing is all over the map, from $959 to $1431 depending on the vendor, with Newegg currently offering the best deal we can find. At the lower end of that spread, you're getting a beautifully built, stabilized cine prime that punches above its weight for Leica M shooters. At the high end, you're flirting with used Zeiss or Voigtlander territory, and that's a much tougher sell. Buy it from the cheapest reputable source you can find, and don't overpay for the privilege of manual focus.

Overview

The Thypoch Simera-C 28mm T1.5 is a cine lens that feels like it was built for a very specific person, and that person probably already owns a Leica M body and hates autofocus. It's a compact, all-metal, fully manual prime that prioritizes character and build quality over clinical sharpness or modern convenience. The T1.5 aperture sucks in light beautifully, but calling it a 'large aperture' lens while the iris only stops down to T16 is a bit of a head-scratcher. This is a lens for deliberate, slow filmmaking, not run-and-gun hybrid shooting.

Common Questions

Q: Does this lens have autofocus?

Nope, it's fully manual focus only. The focus ring is dampened and smooth for video work, but you'll be pulling focus yourself every single time.

Q: Will this work on my Sony or Canon camera?

Not natively. It's an M-mount lens, so you'll need an adapter for anything other than a Leica M body. Adapters exist, but you'll lose any electronic communication and might run into flange distance issues on some mirrorless bodies.

Q: Is the T1.5 aperture good for low light?

Absolutely. T1.5 lets in a ton of light, and combined with the optical stabilization, you can shoot in some pretty dim conditions without cranking your ISO into the stratosphere.

Who Should Skip This

If you're looking for a versatile, do-it-all lens for hybrid shooting, this isn't it. Go get the Sigma 18-50mm f/2.8 instead. It's sharper, has autofocus, zooms, and won't make you fiddle with an adapter. The Thypoch is for purists who want a specific, manual, cinematic look and are willing to sacrifice convenience to get it.

Verdict

The Thypoch Simera-C 28mm T1.5 is a niche lens that knows exactly what it is and doesn't apologize for it. It's a joy to hold, a pleasure to focus, and it makes you work for the image in a way that modern AF lenses don't. For dedicated Leica M video shooters who prioritize build and character over versatility, it's a strong recommendation. For everyone else, the lack of autofocus, mediocre macro, and weird T16 limit make it a tough daily driver. Rent it first if you're on the fence.
