Sony's Xperia Z was among the more insteresting products at CES with an impressive 13MP Exmor RS image sensor and HDR video mode.

The Consumer Electronics Show held this week in Las Vegas, Nevada, showcased some of the most cutting-edge technology available, from washing machines to smartphone cases. 

We've been hustling hard at the Las Vegas Convention Center all week to report on the latest tech trends related to mobile photography, and thought we'd recap with a look at what was trending at CES 2013: 

  • Smartphone newcomers and 13-megapixel devices: From the more experienced large manufactures like Sony who used CES to up their game with the impressive 13MP Xperia Z to the relative newcomers in the high-end device sector like Chinese manufacturers ZTE and Huawei who also showcased 13MP phones at CES, the Grand S and Ascend D2, respectively, the smartphone focus at CES was lesser-known players and a new standard megapixel size. Lenovo also joined in with the 13MP K900. We're excited to see what the pressure of more manufacturers paying serious attention to the cameras in their phones will do to the market, and what 13MP, rather than a previous 8MP standard, will mean for mobile photography. The 5-inch size (the Lenovo deviates slightly at 5.5 inches) and 1080p screens of these new phones also seemed to be the new measurements for high-end smartphones. 
    Sharp showed a prototype of an 85-inch 8K LCD screen at CES.
  • Outstanding new screen resolution: We were blown away by Sharp's 85-inch 8K LCD screen prototype. At 7680 x 4320 pixels, the screen offers 16 times the resolution of a standard 1080 TV and would allow you to display a 33MP image without any downscaling or cropping. While Sharp may have shown off most, the majority of TV manufacturers at CES displayed at least one 4K (3840 × 2160) model. These screens offer four times the resolution of a Full HD (1920 x 1080) TV. Panasonic also showed off a 20-inch tablet prototype with 4K resolution.
  • GoPro knockoffs: Manufactures got into the GoPro action by showcasings several cases and cameras that replicate the sports action photography favorite. One of those which stood out was G-Form's G90 case with a wide-angle lens attachment that essentially turns any number of smartphones into a GoPro-like device. But several more manufacturers also offered their take on the popular GoPro.
  • Rugged smartphone cases: Everywhere you looked there were people dunking smartphones in water, shooting them with paint balls or hitting the devices with a hammer. If CES is any indication, smartphone abuse is going to increase in 2013.
  • Tools to make your smartphone feel like a camera: From's foto.sosho line of iPhone cases to a new Taiwanese accessory maker doing something quite similar, to the Snappgrip accessory that adds a grip to your phone, manufacturers want to make your smartphone more camera-like.
  • Connected cameras: Traditional camera manufacturers still have a long way to go to make their products more attractive to the always connected Instagram generation but more cameras than ever offered at least basic Wi-Fi connectivity that allows image transfer to a mobile device and/or remote capture. The models from Panasonic add NFC technology to the mix and Polaroid showed the first Android powered camera with interchangeable lenses.
