Regardless of zoom levels or other disadvantages, this is a honest comparison of true results you would get from each phone. It's a moot point to argue technicals you have no control over. Overall, the 920 just seems way clearer, and objects have much sharper edges.

I noticed that too - the colors seemed deeper and richer as well. The colors on the iphone seemed a bit washed out.

Just another reason I will most likely get a WP when I'm due for another upgrade this winter.

If we're honest, this is hardly surprising. Before Nokia made it's commitment to Microsoft, they were a company at the forefront of phone technology, including their cameras. However, what this does actually do is beg the question of why they opted for Microsoft. I'm without a doubt in my mind that if they were making Androids right now, they'd be dominating.

However, what this does actually do is beg the question of why they opted for Microsoft.

1) It differentiates them from the sea of Android phones.

2) Nokia's CEO, Stephen Elop, was a former head of Microsoft's business division. So there was already a (presumably) favorable relationship in place.

All of the others seem "zoomed in". I've heard someone say it's because the others use digital stabilization, which means they have to crop the middle of the image to stabilize it against the edges, or something like that. Is that true? Because then OIS seems to significantly improve image quality in video recording as well.

To me it looks like the "others" have far lower bitrate than the Nokia. It'd be interesting to see the originals.

OIS has the added advantage that it makes the video encoder's job easier, since there's less motion to compensate for. A stabilized video will show fewer artifacts when encoded at the same bit rate.

Others have mentioned the different "zoom" levels already. Please correct me if I am wrong but doesn't the zoom level have a direct impact on the differential caused by movement of the camera?

Imagine the following: You have two microscopes mounted on a similar device like seen in the video. The first microscope shows everything two times larger than the second one. If you move "shake" both microscopes the same way you will see more "shakes" when looking through the first one. Isn't that correct and can't this be applied to what is shown in the video?

Yikes, that is quite a large phone. Lumias look like great phones but must they be so large?

It is large. It's thicker than my HTC Titan, but I suspect it will feel really good in your hand. As it is now, the only surface contact I have when holding my phone are the edges.

I wouldn't mind giving up a little thickness for comfort holding the device. I think in the race to make things thinner we might have gotten carried away. Imagine a phone as thin as box board...now imaging trying to hold it.

Engadget has been suspiciously friendly to Nokia lately (I haven't seen them take so many interviews with so many employees from one company before), but I still find it hard to believe that they would increase the zoom level themselves for the other smartphones to make them look worse on purpose. Surely there has to be another explanation for why all the other smartphones look zoomed in.

Earlier quoted context omitted.

>4. No, because post processing can only solve relative stabilisation between frames of video, it does not work within one frame. Apparently you haven't seen this: http://www.youtube.com/watch?v=XLLJBfRzXIQ#t=0m57s

try doing it in a mobile device with 30 full hd frames per second... Still, it's pretty amazing, pity it isn't actually in CS7

Who says post-processing has to be in real time?

re: engadget being suspiciously friendly to Nokia.. i think that if you're willing to actually send a reporter to Espoo, Finland (of all places), Nokia would likely be happy to provide access. especially so, given what now appears to have been a significantly overblown reaction to their introduction of the technology (as the actual usage results appear to validate what was demoed, even if not shot with the Lumia at the time)..

and the Lumia 920 camera apparently has a narrower focal length (which results in a wider field of view), so it can capture more on-screen than than the iPhone; hence it looking particularly 'zoomed-in' when compared side-by-side.

additionally, and i'm not entirely sure about this, but the digital image stabilization software (in contrast to Nokia's actual/mechanical OIS) found on the other phones may have some cropping involved to help smooth-out shaking which would be typically most noticible around the edges..

Depending where the camera is located on each phone, that foam holder will "amplify" movement on the outer sides. I hope they put the phones with the cameras near to the center inside it and switched them too. Otherwise this might be very wrong.

I hope they positioned the phone how someone would actually hold it when they were taking the video. For example, on the iPhone I'll always hold the phone with the camera at the top (portrait mode) or the camera to the right (landscape mode) since the volume buttons will then be up.
