The first review of the new Light Lens Lab 35mm f/1.4 11873 double aspherical AA replica lens for M-mount (get 5% off with code RUMORS) is already online – here is a quote and a recap:
“The lens performs pretty much as well as the excellent previous version. Which is to say very reminiscent of the Leica original. Actually, it is better with my digital sensor, and without any appreciable chromatic aberration or flare. I would have been quite satisfied owning the earlier version, but this is better still. It is everything I have been waiting for.” (Macfilos)
Recap of the Light Lens Lab 35mm f/1.4 Double Aspheric Replica Review
- Introduction and Background: New version replicates Leica Summilux 35mm f/1.4 (11873); improves on earlier prototype’s chromatic aberration (CA) and flare; optimized for digital sensors while preserving “Leica Glow.”
- Build Quality and Design: Features molded aspheric elements, manually polished; added high-refractive low-dispersion achromatic element with lanthanide glass to reduce distortion, diffraction, and CA; rear element extended for better sensor spacing; chrome prototype tested, slightly larger size; uses E46 hood (not included).
- Optical Performance: Sharp at f/1.4 with rounded center; minimal CA compared to Leica APO-Summicron 35/2 (negligible differences at 100x zoom); improved veiling flare suppression, though some internal reflections when shooting into sun; bokeh maintains vintage “Leica Glow”; edge sharpness good but with minor fall-off and field curvature; strong performance in scenic shots at f/4–f/5.6.
- Handling and Compatibility: Rangefinder coupling slightly long at f/1.4 (requires Visoflex for critical focus), accurate for f/4+; well-suited for high-res digital sensors; tested in Montreal with cropped and atmospheric images.
- Comparisons: Superior to prior LLL prototype (less CA/flare); matches or exceeds original Leica 11873 in rendering; no significant CA vs. APO-Summicron; blends vintage character with modern refinements, potentially Leica’s best 35/1.4.
- Pros: Reduced aberrations, flare, and distortion; sharp with classic glow; modern digital optimizations; great scene presence.
- Cons: Minor edge fall-off and field curvature; rangefinder focus limitations at wide apertures; some residual reflections.
