LG outs a promo video touting the ultra slim 13MP camera in the Optimus G, says it will be 8MP "in some regions"

We got confirmation from LG that the camera module is made in-house by LG Innotek, and the video confirms this, so most everything but Qualcomm's chipset will be LG-made in the Optimus G, just like the big brother Samsung does and wins. There is a small print disclaimer in the beginning of the video, saying that both an 8MP and a 13MP version of this sensor have been developed, and the phone will come outfitted with one or the other, depending on the region. The US will likely get the 13MP one, considering the rumors around the LG Blaze for Verizon.

While one of the optics department's chiefs touts the ultra slim packaging of the 13MP camera module, saying that this is the highest resolution in a smartphone (apparently they don't consider the 808 PureView one), and its BSI sensor and other enhancements make it a top-notch technology, somehow we are hesitant, considering the specs revealed in the video.

While the resolution may be high, it is achieved by shrinking the pixels, so they can fit in the ultra compact module, down to 1.1 microns and with a mere 1/3" sensor size, its performance is unlikely to be drastically better than those of other flagship smartphones that have similar specs. The sample shots will be the ultimate judge, but just for comparison's sake - the Nokia 808 PureView has a 1/1.2" large sensor with 1.4 microns pixel, the Lumia 920 has 1.4 microns as well, on a 1/3" sensor, and the Nokia N8 has 1.75 microns pixel size on a 1/1.83" 12MP sensor. 

Even if we don't count those photography buffs from the Finns, the Galaxy S III and the iPhone 4S also have 1.4 micron pixels in their sensors, and we know the larger the pixel "bucket", the more light it can soak in.

Thus the Optimus G is unlikely to wow in low light conditions, judging on camera specs alone, but, still, any improvement from LG's current high-ends will inevitably make the upcoming LG flagship more appealing in the camera department too.
