In year, Oppo showed us smartphone technology that they said would bring 5x optical zoom or ZOOM may refer to to devices. Unfortunately, it never materialised but the comrades has sent out invites to an event (happening tomorrow) that could see a smartphone with a 10x optical zoom instead.
Chinese Tech site My Drivers are the geezers who have shared their invite online and when you translate it, the words say '10x the view'. The invite doesn't reveal much else aside from from the event date and some fancy graphics.
If a smartphone with a 10x optical zoom is revealed, it could grab the attention of smartphone photographers as up until now, the maximal optical zoom we've seen in most smartphones is 2 or 3x. There are smartphones with much longer digital zoom reach but the worth of digital zoom is rather poor with a loss of detail and noise spoiling shots. Optical zoom, on the other hand, preserves particular so images captured with the longer end of the zoom have a higher level of quality.
Space is also limited in smartphones so if the rumours are honestly, it'll be interesting to see how Oppo squeeze a 10x optical zoom in and if the device on show will be anything more than a prototype.
