Review of the Thypoch Simera 35mm f/1.4 lens.


🧾 Overview

  • First on market 2023 from Indian firm, Thypoch.
  • Compact, relatively affordable.
  • Uses a floating elements design (uncommon at this price), allowing closer focusing (0.45 m).

👍 Strengths

Image Quality

  • Sharpness:
    • Good in the center even wide open.
    • Improves significantly stopped down (best ~f/8).
  • Bokeh:
    • Smooth, modern rendering.
    • 14 rounded aperture blades keep highlights circular.
  • Low distortion:
    • Minimal and rarely needs correction.
  • Chromatic aberration:
    • Well controlled overall (especially lateral CA).
  • Sunstars:
    • Surprisingly good despite rounded blades.
  • Optical balance:
    • No major flaws typical of fast compact 35mm lenses.

⚖️ Average Performance

  • Vignetting: Typical for a fast compact lens.
  • Flare resistance: Decent but not outstanding.
  • Coma: Noticeable wide open; improves by f/5.6.
  • Size/weight: Reasonable but not class-leading.

👎 Weaknesses

Handling (main criticism)

  • Focus ring:
    • Too narrow and awkwardly placed.
    • Very short throw at close distances → hard to focus precisely.
  • Infinity lock:
    • Annoying and slows down shooting.
  • Aperture ring:
    • Irregular click spacing makes it hard to use by feel.
  • Overcomplicated depth-of-field scale that isn’t very useful.

Optical Issues

  • Focus shift: Noticeable (especially around f/2.8).
  • Wide-open softness at close focus (improves when stopped down).

📷 Best Use Case

  • Works best on Leica M cameras (optimized for thin sensor stack).
  • Suited for:
    • Street photography
    • Environmental portraits
  • Less ideal for:
    • Fast-paced shooting (due to handling quirks)
    • Sony mirrorless bodies (weaker edge performance)

🧠 Final Verdict

  • well-balanced optical performer with no major flaws.
  • Strong value for money, especially given the floating elements design.
  • However, handling is the biggest drawback and may be a dealbreaker.
  • In short: A technically solid, optically pleasing lens—but ergonomically frustrating. Worth considering if you can tolerate its quirks.
