Unless you’re as into mobile phones as we are — and that’s pretty hard — you might not have heard about Sony’s follow-up to the Z1, with the Z2 coming soon and sporting some similar specs, such as the 20 megapixel camera.

But the Z2 has 4K recording, so will the Z1 get an update to support Ultra HD shooting?

Apparently, the answer is no.

In fact, after some nudging, a representative from Sony had this to say on the matter:

“The 4K recording capability has more to do with the camera capabilities and less to do with the processor. Specifically, there is an additional sensor capability within the Z2 that enables you to decide whether you shoot in 2K (standard definition) or 4K. This was not built into the Z1 and therefore it will not be upgradeable.”

While the hardware on paper looks pretty spot on from the camera point of view between the Z1 and the Z2, it appears the two handsets aren’t the same, at least not according to Sony.
