The MWC 2013 in Barcelona has seen a plethora of smartphones announce their arrival. Two new smartphone offerings that stand out in the hotly contested smartphone space are the HTC One and Nokia Lumia 720.

The flagship HTC One is a top-of-the-line handset which is looking to give the current smartphone biggies a run for their money. The HTC One features the much-touted UltraPixel camera with HTC Zoe, which has the ability to gather 300 percent more light than traditional smartphone camera sensors.

The Taiwan-based company claims that the "breakthrough HTC UltraPixel Camera redefines how people capture, relive and share their most precious moments," whereas HTC Zoe enables users to capture high-resolution images "that come to life in three-second snippets."

Finland-based Nokia's Windows Phone 8-powered Lumia 920 has been making waves since its November 2012 release and the device's 8.7-megapixel primary camera with its Carl Zeiss optics is touted as one of the best in the current crop of smartphones. Nokia launched the mid-range Lumia 720 at the MWC 2013 with a 6.7-megapixel front-facing camera that too boasts the Carl Zeiss Tessar lens.

The Lumia 920 has struck a chord with both consumers and tech pundits alike thanks to its low-light camera performance. However, the top-end handset now has competition from its own sibling, the Lumia 720, as well as the HTC One.

The video below takes a look at the low-light capabilities of all the three smartphones as they take the same picture in the same conditions.

The Lumia 920 may be the reigning champion, but judging by the video, it seems that the budget-friendly Lumia 720 is set to give the smartphone some stiff competition and even holds its own against the high-end HTC One.
