Better optical glass formulations ? What was considered the 'reference' in those days in 35 mm photography ? Early Summicron ? Alpa ? OR: When did Summicron become available ? Sonnar VS Planar ? Is the 'Bokeh Factor' a valid consideration for these lens types ? How about a Planar LTM around f/2 ? 35mm ? 50mm? Did such ever come to the light of day ? Were Sonnar aficionados ever justified ? I think I've seen some non LTM Sonnar with quite impressive 'specs' for circa 1935 ... A 28mm or 35mm Biogon LTM ????? !!! f/2.8 would be 'just fine'. So much for my Zeiss Ikon anxieties ... :+) Andre Jean Quintal
