These results are only provisional as the lighting level is the test scene has been adjusted since the other phones were shot.

Despite the lower lighting level, the Nokia is able to out-perform its rivals by a healthy margin. Fine detail is better maintained and the image is generally "cleaner." This benefit (that comes from a combination of a larger sensor and the noise-reducing effect of downscaling images), is one of the significant advantages of Nokia's decision to use a large sensor in a smartphone. Whether you look at the resolution stripe on the left of the image or the etched portrait on the right, the 1020 is significantly out-performing its rivals.

We plan to re-shoot the rival phones, to make the low-light scene more directly comparable.

Conclusion

We can only truly give very a preliminary conclusion at this point based on a day of playing with the device, but we are excited about what we've seen so far. 

One of our favorite initial aspects of using the Lumia 1020 was the grip accessory. Priced at $79, the gadget is bound to be popular amongst mobile photography fanatics.

From an imaging perspective, the Lumia 1020 appears to be just what we'd hoped: a more advanced version of the PureView technology that blew us away when we first saw it on the 808. And this time around, the Lumia 1020 has even more to offer the photographer who wants to use their mobile as a serious camera. From OIS to an even faster lens to that add-on camera grip that nearly had us convinced we were using a "real" camera, the Lumia 1020 seems to offer a lot of potential. Our initial trials with the device's auto mode don't explore the Lumia 1020 fully; we need to delve further into the camera's actual imaging capabilities: it's here that we'd like to see what this camera can do. 

We'll look forward to sharing a full gallery of Lumia 1020 images soon, and a more thorough review of the camera as soon as we can.
