Do Point and Shoots Have Lens Mounts?
Many people like the convenience that point and shoots offer them. These are portable and easy to maneuver. They are certainly much smaller and easier to use than any digital SLR camera. Digital SLR cameras have the advantage of having interchangeable lenses, but are much larger. There are, however, lots of point and shoot cameras that have lens mounts, which makes them much more flexible.
Although there are a few competing systems, none of them are quite as good as a SLR camera. However, these give you a very good compromise, which allows you to use different lenses for different types of photography.
Micro Four Thirds
The micro four thirds system was developed by Panasonic and Olympus. This is a type of lens mount system which is designed for compact point and shoot cameras. There are a few cameras which use this system including the Lumix G1 and the Olympus PEN E-P1. The sensor is smaller than a DSLR camera, which means that quality is slightly worse. However, the quality of the images is better than most point and shoot cameras.
The Sony NEX range of cameras also have lens mounts. This is similar to the micro four thirds system. The latest camera in the range is the NEX-5. This has a 14.2 megapixel sensor for high quality images. There are many different lenses available, including a fish eye and macro lens.
