A:AnswerA phone will do fine for blogs and many photos in many situations, but the tiny sensors and fixed lenses can';t compete with the the large sensors and pixels of a real camera. Dynamic range, spillover to adjacent pixels, and noise are issues with all sensors, but decrease with the size of the pixels. Around 8 meg resolution seems to be the optimum compromise of these 4 components in the tiny sensors in phones.
A:AnswerNo and yes, the camera itself isnt meant for low light you will see grain at around 6400 iso but if you invest in a good prime lense it will let more light in and you can shoot into the evening but with this camera and kit lens youll probaly notice really grainy photos around 6 or 7 pm if your shooting outside
A:AnswerVery good, but you might want to move beyond the kit lenses for really critical photos. Noise, dynamic range, and lens are the big factors. Learn about dark frame subtraction for the best results for any camera.
A:AnswerI received the bag as a gift when I purchased the camera with the lens kit. No lens come with the bag. You'd have to get the lens kit bundle or buy the lens separately
