Summary: I own the WX300 and did not see any substantial improvement in the 350 so returned it. But both are very proficient in low light and have remarkable zoom for such a small body. WiFi works fine, set up to remote control the camera by my Samsung tablet, and works well as a baby room monitor also...!! I'm an owner of a NEX 5N and looking at the new A6000, but I am still impressed by the pictures and video of this tiny box.
Summary: I purchased this camera to use when I don't want to lug around my RX100. It works great outdoors and the 1080p/60fps video is very nice. However, almost every shot I have taken indoors has been ruined by the flash washing out the picture. It is very strong and there is no real way to control it. You can control it to a certain point by using the exposure compensation feature, but what it really needs, and is missing, is flash compensation.
