Pocari Sweat and Calpis are fantastic drinks, nothing better here in NY, but brand naming is notorious in japan, for example, the Mitsubishi Pajero had to be re branded to Montero in Latin America because Pajero is a bad word if you speak Spanish.
Regarding the lack of information. What fun would it be to get all the details at once ... and in English ??
If so I'd break open the bubbly. My Mamiya needs a couple of leaf shuttered schneiders. Especially a 50, a zoom and a 150.... f2 plz.
Looking at the Pentacon website it seems that their brand is widely marketed today. Maybe there is better name recognition for Pentacon in Japan than Schneider? Seems unlikely but... if the Japanese really want 654 film cameras in 11 disgusting cameras then lord knows what brand names sound better! Remember in Japan people like drinks with names like 'Pocari Sweat' and 'Calpis'
The 'Pentacon' name is formed from PENTAgonal as in prism in viewfinder and CONtax, so it doesn't suggest a lack of quality.
