HMD is taking the time to get the Nokia 9.3 PureView right and a lot of effort is going into the camera. We already heard that it will use a 108MP sensor, now sources are claiming that the camera may record 8K video at 30fps, reports Nokia Power User.
This is only if the engineers are happy with the results, of course, so they are reportedly hard at work, trying to finalize the image processing algorithms. Part of what makes 8K possible in the first place is the Snapdragon 865 chipset, which replaced the S855 that the phone was going to use initially (this phone has been delayed several times already).
As for still photography, the HMD team is focusing mainly on the Pro and Night modes. For Pro mode, they are refining the image processing algorithms and manual controls. Night mode will get the benefit of larger pixels (presumably thanks to binning) and OIS.
ZEISS will also be contributing to the camera with exclusive ZEISS effects. The exclusivity bit is important since Sony is about to release a phone in partnership with ZEISS too.
After all these leaks, theres little in the way of official confirmation that the phone even exists. Juho Sarvikas did tease possible color options and the phone is supposed to come out in August or September, but thats still months away.
