What We Like
+Exceptional sharpness and center detail at f/1.4 with excellent mid-field performance; reaches optimal resolution by f/2.8
+Compact and lightweight (372g) for a fast 75mm lens; significantly smaller and lighter than Leica Summilux 75mm f/1.4
+Smooth, creamy bokeh with 16 aperture blades and premium chromatic aberration control outperforming competitors
+Beautifully machined all-metal construction with fluid focus and aperture rings; improved design without focusing ring lock of earlier Simera models
+Versatile de-clickable aperture ring and 0.6m close focus distance make it suitable for both stills and video
+Excellent value at $849–$850; strong performance alternative to significantly pricier Leica and Voigtländer options
Worth Knowing
−Corner sharpness softens at wide apertures (f/1.4); benefits from stopping down to f/5.6–f/8 for excellent corner performance
−Requires manual focus with short throw; focus precision at f/1.4 is a learned skill, especially on rangefinder bodies
−No weather sealing; barrel design has openings that make it unsuitable for adverse weather conditions
−Minor focus shift and occasional purple fringing on high-contrast edges at wide apertures; requires stopping down and refocusing for optimal results

About This LensThe Thypoch Simera 75mm f/1.4 ASPH is the fourth lens in the Simera f/1.4 series, continuing the legacy with its blend of modern optical technology and retro design. This compact, high-speed medium-telephoto lens offers a 49mm image circle, making it compatible with sensors larger than full-frame, expanding its potential for use with medium format systems. The Simera 75mm f/1.4 ASPH offers a well-balanced mix of smooth rendering and solid performance. The optical design incorporates 1 aspherical lens, 2 high refractive index (HRI) lenses, and 2 extra-low dispersion (ED) lenses that effectively control chromatic aberration and flare, and Thypoch's high-precision aspherical technology nearly eliminates the "onion ring" effect, delivering pure, smooth bokeh. | |
