    Here's a few pics I took with my 1520 last night at a pub:

    I then took a picture of the same object with both the 920 and the 1520 (the 920 pic is on the left, 1520 pic is on the right):

    Can you provide the EXIF data from the 920 image? Just wondering what was the shutter speed used to capture this.

    The think is that 920 can soot almost twice lower ISO value compared to 1520 when using same shutter speed. When using auto settings on both devices 920 wins if light is really low. In those cases 1520 ISO value goes above 1600 and image quality takes very big hit and there is tons of noise and you can see visible dark lines in 1520 photos.

    If you want take equally good pics as 920 you need to use manual settings. There's nothing wrong in 1520 low light images. It is just that 2.4f aperture that needs to raise ISO too much on auto settings. 1520 have great image stabilization and you can very well shoot with even 1 second shutter speeds. That compensates difference to 920 2.0f lens.

    My issue is its a newer phone, by this I mean when you make a flagship phone its sets a standard (your best at that time) so when you come to make the next flagship phone you improve on the last one, be that cpu/screen/gpu/camera/battery.

    With a new phone you would also hope a company learns from its mistakes in the past.......so why does the 1520 show signs of a step back.

    For sure.

    For the 920
    f-stop: f/2
    exp. time: 1/4 sec
    ISO: ISO-1600
    exp. bias: 0 step
    metering: average

    For the 1520

    f-stop: f/2.4
    exp. time: 1/4 sec
    ISO: ISO-1600
    exp. bias: 0 step
    metering: average

    This info was pulled from the Details tab of the properties of both photos. I should also note that both pictures were taken using the Nokia Camera app with everything on default settings (save for flash/focus assist being off).

    It will be the ratio of the f numbers, squared. In this case, 44% more for the f/2. The relative sensor area can also be measured in similar way, if the sensor size is measured by inch (") you will need to square it. It may vary slightly depending on the aspect ratio of the sensor.

    The 920 generally tends to over-expose all lowlight shots, therefore to compare the image quality you need to increase the 1520's exposure (manually). Of course this will result in more noise but this is necessary to assess the impact of sensor versus lens. The other thing is we need to compare the 920 at full resolution. My guess is that the 1520 at oversampled 5mp still has an advantage at pixel level.

    You made a good point. Lumia 920 is an excellent device. With minor issue of heat, random battery draining, low speaker volume and its camera taking soft images under normal lightening conditions. I am not sure if Nokia will fix this issue with a firmware update. Because it is more than an year old flagship device.

    Lumia 1520 which is a generation ahead of 920, despite its not a flagship device or a successor of 920. It is like a big brother of 920. Nokia should have overcome the limitations posed by 920. But instead of that, they downgraded it by reducing the size of lens, aperture, thus producing horrible low light phots and videos.

    Everyone doesn't like to oversample images to 5MP. I think their oversampled iamges should have been 8MP instead of 5. Is it something hardware base or an upcoming firmware can provide the option of oversample in 8MP as well as 5?

    I actually think the 1520 is a step ahead of the 920. The 1520's 5mpx output can match the 920's 8mpx; the 1520's larger sensor and oversampling technology does provide a much higher quality image.

    Granted, the 1520 suffers from some bugs. And I'm not surprised - after all, the 1520 is a brand new lens assembly.

    The 920 has been out for a long time now so Nokia has had a lot of time to tweak it. Remember the Amber update that made every photo turn out a bit more green/yellow? How about the softness issue before Amber corrected it?

    Given Nokia's track record and emphasis on photography, I'm sure Nokia will fix the few issues with the 1520.

    But even after Nokia Black update, people have complained about softness issue under normal lightening conditions, and acknowledge that Nokia is ignore its 1 yr old flagship device, because of its total focus on new devices.

    I own both 920 and 1520. Personally, I do believe the 920 takes better low light pictures but the 1520 isn't that far behind and in most cases it isn't noticeable. The one reason I prefer 1520 is DNG editing... I know a lot of people don't won't to have to do post work on their photos but you could get rid of most of the noise issue and adjust white balance a lot easier and better than the 920.... Making a much more flawless photo.wp_20140120_18_34_38_raw__highres.jpg

    Despite the lower resolution the 5MP image still retains a very good amount of detail and has much cleaner output. When using the 808 I was almost exclusively shooting at 2MP and even then it was more than good enough for viewing at full screen with near noise-free image.

    I believe the ProShot camera app allows you to select different resolution options. In any case you can always save the RAW and downsample to whatever resolution that you want.

    I believe the initial feedback on 1020 is that some people prefer a more natural, less sharpened look and it seemed Nokia may have toned down the sharpening/saturation in Black. So it may now look a bit soft. In fact, if you look at the 808's images it tends to be rather soft although rich in detail.

    I also wouldn't say that Nokia is ignoring the 920. The 920 already has pretty good image quality for its time, and among its peer. Given the fixed hardware it may be difficult to push any major improvements to it unlike for the 1020. For example, capturing RAW does make more sense for cameras with larger sensor (i.e. 1520 and 1020). Likewise, if Nokia were to develop Lytro-like technologies in future, it would be impossible for them to transfer such technologies to the 1020 simply because of hardware limitations. Granted they can continue to optimize the imaging algorithm (which they did with Black), or introduce new camera apps (which they did with Refocus/Nokia Cam), but you can't expect any major improvements on the 920. My reading of Nokia's strategy is that they are going to focus on new breakthrough technologies, but where possible they will try to push new things to lower devices. Think about it, the 920 did not originally come with Nokia Smart Camera, it was supposed to be a new feature for the 925, but eventually it came to the 920 as well. If there is enough demand for it perhaps Nokia may someday enable RAW capture for 920, but I think at this point the 920 may not benefit too much from that.

    What I think all the Pureview devices need at the moment, is the ability to determine the sharpness/saturation level. This is something missing in the 1520/1020 as well. I do think they will enable this option at some point, and likely the 92X will benefit from this.

    Looks like, even after purchasing 1520, I will keep my 920 for video recording and low lights.

    Ah, looks like it's correct for now - the 1520's low light features are somehow worse than the 920's.

    Here is demonstration how big difference there is if you use auto settings or manual settings for low light photos.

    Auto settings https://lyczeg.dm2302.livefilestore....Pro.jpg?psid=1 ISO 1000 1/6s
    Manual settings https://lyczeg.dm1.livefilestore.com...Pro.jpg?psid=1 ISO 200 0.75s

    Little bit more light
    Auto settings https://lyczeg.dm2304.livefilestore....Pro.jpg?psid=1 ISO 800 1/11s
    Manual settings https://lyczeg.dm2301.livefilestore....Pro.jpg?psid=1 ISO 100 0.75s

    As you can see high ISO value ruins image quality quite large scale. I just set ISO manually to 100 and 200 and OIS took care of rest. 0.75s shots and very sharp looking still.

    Maybe future updates makes thinks better and highrer ISO values doesn't ruin photos so much. Just don't use auto settings on low light shots

    I'm ok with having to manually adjust settings, but one thing that is (was?) nice is that you can bring the phone out of your pocket and hold the camera button, and be ready to take a pic in no time at all.... Oh wait hold on.... Need to adjust because it's dark. Just a second... Ok... now let's take the pic. Meh, it could be worse; at least it does very well on manual settings. Sometimes that can cause you to miss your window though.

    I don't know what they're going to do about the crap video in low light though.... It's shamefully bad.

    I do miss the camera's overall "feel" from the 920.
