Camera
So now let’s talk about what the phone is all about. The camera. The K550i’s 2-megapixel camera, in all honesty, is just good. Not great but good. There are plenty of options to select from for shooting in different modes. The pictures themselves are quite clear.
The close-ups in macro mode show up clear but just a wee bit grainy. But the colors seem to be captured accurately enough, although the greens do appear a bit on the bluish side. But the yellows and pinks are quite good. So in fact, the close-ups on the whole are quite decent.
Outdoor pictures are really good if you can hold your hand steady enough. The K550i manages to take pictures with a decent amount of clarity however; there is a visible amount of pin-cushioning around the edges of the images.
Although for I'll admit it's great having so many settings for the camera, the interface for choosing those options remains unchanged and if I were a first time user, it would be a bit complicated to find the right settings. It is a Cybershot though, so it's expected to have settings for various shoot modes including burst, panorama and quite few odd frames to have fun with. Scene modes include settings for shots that you can take in twilight landscape or portrait, beach, snow, and even a sports mode. You also have the option of choosing the picture size from VGA to 2megapixels. The K550i also has a self-timer option and effects like - black and white, sepia, negative and solarize. You can even adjust the white balance for various light settings. You even have options for metering mode and inserting the date and time. Like I said, plenty of functions.
