Dobrý den, v popisku u telefonu uvádíte "Zadní fotoaparát s optickým zoomem 12 Mpx (f/1,8) + 12 Mpx (f/2) + 12 Mpx (f/2,4)" "Optický zoom" je v tomto případě tři různé objetivy pevného ohniska, nikoli zoom. "Dále 12Mpx (f/1,8)..." To jsou údaje o rozlišení čipu a cloně objektivu, které jsou sice důležité, ale informace je neúplná. U každého klasického objektivu se uvádí obě hodnoty (ohnisko a clona), neexituje případ, že by nějaký obchod měl v nabídce objektiv f/2,4. (To je jako by měl prodejce v popisu v katalogu automobilů bílé auto s motorem). Pro úplnost by tedy mělo být uvedené 13mm f/1,8, 26mm f/2, 52mm f/2,4.
