Spec Notes
LENGTH OMITTED - two sources give 41.6mm (flange to front at infinity) and 52mm, almost certainly different measuring conventions rather than two lenses. Minimum aperture NOT SOURCED; a blanket f/22 claim for the whole IIIS range conflicts with per-lens f/16 figures elsewhere and was not used. Couples the IIIS rangefinder but has NO viewfinder frameline - an accessory 28mm finder is required.
