Promo material suggests Sony Honami smartphone may shoot 4K video

Alright, we admittedly don't know a great deal about the provenance of the slide above. It was first picked up on Chinese social networking site Weibo, but the original post seems to have been deleted. What we do know, however, is that Sony's forthcoming flagship phone, codenamed Honami, has already been rumored to possess a 4K-ready processor (the Snapdragon 800), and that Sony is wildly enthusiastic about 4K as something that can unite its expanding hardware ecosystem. The slide's title therefore has a ring of truth to it, because it's accompanied by Bravia branding and sounds like realistic marketing babble from a TV-focused presentation:

"How do you get 4K content? By shooting videos with a 4K cellphone."

The slide also details a 20-megapixel Exmor R rear camera sensor for Honami, which tallies with earlier reports, as well as a meaty 2.2-megapixel front-facing camera. The only issue we have is with the quoted 4K video resolution of 4,000 x 2,000 -- it's unusual and doesn't match the Ultra HD resolution Sony has settled on for its 4K TVs (3,840 x 2,160). In any case, resolution is only half the story. This is all speculative, of course, but if other bottlenecks in this phone forced Sony to compress the heck out of captured 4K video, there's every chance it'd end up looking worse than 1080p.
