We were able to go hands-on with both models -- they feel much more solid than Sony's less-equipped Handycams, such as the CX380 and PJ380, likely due in no small part to the large Balanced Optical SteadyShot module at the cameras' core.
Both include Balanced Optical SteadyShot, which moves the entire lens module (not just specific elements) for much more effective stabilization, especially when zoomed in.
Nokia's Lumia 920 packs the industry's best image stabilization -- there's no questioning that -- thanks to a camera module that pairs both sensor and lens-based optical IS. The iPhone 5 also offers a notable improvement over its Apple-made predecessor on the video front, but considering that its stabilization is of the digital variety, we wouldn't expect it to top Nokia's new flagship.
