A Smartphone with Greater Focus - UPDATED

It's out there, I'm not claiming to know what it means. 

"Infinite focus" is "greater."

UPDATE: Something it could be -- but they don't know either.

The term 'greater focus' in the tweet might be referring to the inclusion of the Hybrid AF technology (which combines phase detection and contrast autofocus systems) in the unannounced Sony Xperia Z5, just like the recently launched Xperia M5.

-- END UPDATE

September 2, 2015

Not that there was any doubt, but Sony Mobile has confirmed that a new smartphone “with greater focus” will launch at IFA 2015 on 2 September 2015. We expect that Sony will launch a new Xperia flagship,  along with a smaller ‘compact’ sibling. Sony is most likely to market these as the Xperia Z5 and Xperia Z5 Compact. A phablet version is also expected by the end of 2015, but this may not be ready for an announcement at IFA.
