1. Physical size profile
Dimensions confirmed for Kinoshita Optical KISTAR 28mm F3.2: 41.4 mm long and 62.5 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 7.9 millimetres apart.

Designed to cover full-frame Sony E-mount bodies and compatible with APS-C E-mount bodies.
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.
