    So What Does It All Mean?
    Basically, it all means that you can shoot surprisingly good video clips with many of today’s digital still cameras and surprisingly good still images with a number of today’s digital camcorders. And you don’t have to hock the house to pay for it: These capabilities can be found in models costing less than $500.

    And what does that mean? If you want to experiment with movie-making, you can do it with your digital still camera and enjoy the results. And if you’re a videographer, you can explore quality still photography with your digital camcorder when desired.
     
    Bottom line: Convergence gives you the blend of two worlds. If you’re mainly interested in still photography, but want to do videos, too, get one of the digital still cameras that offers high-quality movie capability. If you’re mainly interested in making movies, but want to do still photography, too, get a digital camcorder that can produce high-quality still images.
