Thypoch Simera Simera 35mm f/1.4

The Thypoch Simera 35mm f/1.4 is a manual focus prime with fantastic bokeh and a lovely metal build, but on Canon RF it suffers from a severe color cast that ruins the image. On Nikon Z and other mounts, it's a sharp, characterful bargain. For Canon users, the Canon RF 35mm f/1.8 IS STM is a safer and smarter buy.

The Thypoch Simera 35mm f/1.4 is a manual focus prime that clearly takes inspiration from classic glass, all wrapped in a compact, all-metal body. At 318g and just 2.5 inches long, it balances perfectly on Canon RF bodies like the R8 or R5, and the declickable aperture ring plus grooved focus tab give it a tactile, old-school vibe that's actually fun to use. The f/1.4 opening is huge for low light or subject separation, and a 49mm filter thread keeps accessory costs low.

But there's a catch that hits Canon RF shooters hard: a severe color cast. Our testing and user reports confirm a distinctly warm, almost sepia-like tint across the frame that software can't fully fix without messing up skin tones. It's not a bad copy situation, it seems to be an inherent design issue on this mount, and it's serious enough that we can't ignore it. For Nikon Z and other mounts, the lens gets glowing praise. For Canon RF, it's a big asterisk.

If you can look past that (maybe you shoot only black and white or love color grading every shot), you'll find a lens with impressive center sharpness at f/1.4 and bokeh that sits in the 90th percentile in our database. But for most of us, a 35mm prime that can't get white balance right is a hard pass.

Wide open at f/1.4, center sharpness is genuinely good, easily resolving 24MP and 30MP sensors without that soft, dreamy look some vintage homages deliver. Stopping down to f/2.8 sharpens the corners nicely, though strong vignetting hangs on until about f/4. The 9-element, 5-group design includes high-refractive index and aspherical elements, so it's not just a nostalgia piece. Bokeh deserves its high ranking, smooth, with gentle falloff and no harsh onion rings, making it a standout for portraits or street shots where you want the background to melt away.

But the optical story has some frustrating footnotes. Purple fringing pops up in high-contrast edges, and the lack of electronic contacts means no EXIF aperture data, no focus confirmation beep, and no in-body corrections for vignetting or distortion. The manual focus throw is long and precise, which is great for video or careful framing, but if you're shooting fast-moving subjects, you'll miss autofocus fast. And that color cast on Canon RF just sits on top of every image like an Instagram filter you can't remove.

On paper, $449 to $619 for a solid f/1.4 prime with this build and bokeh sounds like a steal. But that's on paper. The Canon RF color cast drags value off a cliff. If you shoot Nikon Z, this lens is a hidden gem at the low end of that price spread. For Canon shooters, we'd point you toward the Canon RF 35mm f/1.8 Macro IS STM, which costs around $500 and gives you autofocus, stabilization, close-up ability, and, you know, actual white balance. Even a used Samyang MF 35mm f/1.4 in RF mount, if you can find it, would be a safer bet. Unless you find the Thypoch for under $400 and plan to shoot only black and white, the value proposition unravels completely.

The most direct alternative for Canon RF users is the Canon RF 35mm f/1.8 Macro IS STM. It's a stop slower, and its bokeh won't melt your heart like the Thypoch's, but it autofocuses, has image stabilization, and doesn't tint your world sepia. For pure manual focus fans, the Samyang MF 35mm f/1.4 in RF trim is another option, though it's heavier and harder to find. In the wider mirrorless world, the Thypoch competes with the Viltrox AF 9mm f/2.8 or Sigma's compact zooms, but those are different animals. The real story is mount-specific: on Nikon Z, the Thypoch goes head-to-head with lenses like the Nikon Z 40mm f/2 in brightness and character, often winning on build and bokeh despite the manual focus tradeoff. On Canon RF, it's a non-starter for color-critical work.

Canon RF shooters should skip this lens entirely because the color cast is a dealbreaker, unless you only do black and white photography and don't mind the lack of EXIF. If you need autofocus, weather sealing, or less vignetting, the Canon RF 35mm f/1.8 IS STM is a much more practical pick. Anyone who relies on accurate out-of-camera JPEGs or quick turnaround will find the Thypoch frustrating on any mount, but especially on RF.

If you shoot on a Nikon Z body and crave a fast, characterful 35mm with a vintage soul, the Thypoch Simera 35mm f/1.4 is easy to recommend, especially at around $450. You'll get gorgeous bokeh, solid sharpness, and a build that feels special. For Canon RF, the situation is a hard no unless you only shoot monochrome or love spending time in Lightroom fighting a baked-in color cast. The problem is too severe to ignore, and it undercuts the otherwise excellent optics. If Thypoch ever fixes the RF color shift, this lens would jump to the top of our shortlist. Until then, it's a heartbreaker that Canon shooters should skip.
