iPhone 7 specs: 21-megapixel DSLR-quality camera for next-gen phone?

It is said that iPhone 6's immediate sibling will get a dual-lens system. How's that for camera breakthrough?

The iPhone 7, as what media outlets address the future addition to the Apple smartphone lineup, is getting an early hype. While there are still long months before it is set to put in an appearance in September next year (that is, if the titanic Cupertino company does not revise their release schedule), many believe that the forthcoming Apple flagship is going to be a feat like no other and it is all because of a beasty change in its camera capabilities.
Future specs like sidewall displays and sapphire glass are just two of users' expectations of iPhone 6's would-be successor, and the hottest rumor has everyone hoping that the iPhone 7 (which is also called iPhone 6S or iPhone Air) will be getting the "biggest camera jump ever." According to the IB Times, John Gruber from Daring Fireball revealed during "The Talk Show" podcast that the iPhone 7's camera will be designed to capture DSLR-quality photos.
"I don't even know what sense this makes, but I've heard that it's some kind of weird two-lens system where the back camera uses two lenses and it somehow takes it up into DSLR quality imagery," Gruber said via IB Times.
While it remains a bit blurry for many and even "weird" at the moment, the possibilities of this too-good-to-be-true package remain too huge to ignore. Apple gets its CMOS sensors from Sony, which interestingly announced its newest one on Nov. 17. The latest Sony gizmo was revealed to be a 21-megapixel Exmor RS IMX230 sensor that captures videos in 4K resolutions using HDR imaging technology.
If Apple seeks help with its camera boost from the Japanese company (and that is very likely indeed), it is not impossible that users will be able to get their hands on the first iPhone that is capable of taking ultra high-quality photos. Besides, the iPhone 6 and its 8-megapixel rear-facing camera are inarguably nowhere near a stunner when it comes to this department, and iPhone 7 may finally be Apple's venue to have it majorly overhauled.
