1. Physical size profile
Dimensions confirmed for NiSi 9mm F2.8 APS-C Sunstar: 78 mm long and 74 mm maximum diameter. Mounted on a top view of Sony α7 V, drawn at one millimetre scale from a common mount centre and axis. The top view preserves the traced grip-to-lens relationship; the illustrated edge clearance is 4.4 millimetres apart.
This APS-C lens requires the full-frame body’s APS-C crop mode for its intended image circle.

Designed for APS-C Sony E-mount bodies. Full-frame bodies require an APS-C crop mode for the intended image circle.
Mounted profiles compare physical size only. Equivalent field of view and objective multi-lens comparison remain planned for Phase 3.
3. Sharpness profile
Under construction · Phase 4Sharpness evidence
No inferred sharpness scores are shown while the observation schema and normalization method are unfinished.
4. Bokeh profile
Under construction · Phase 4Bokeh evidence
The future profile will summarize sourced observations, not simulate this lens’s optical output.
