              i bought a nikon L100, to be honest at first sigh i was dissappointed, cause this camera Lacks of manual settings which is the most important thing for photography, but with time i learn how to manage this camera and then i found it wasn´t that bad, anyways i know why the quality of this camera (nikon L100) lacks its cause the sensor size is really Small. but is a good camera for particular usage but not for those who want to learn about photography.
