While it can be tempting to bring a wide arsenal of lenses on a shoot, sometimes you really only need one. Being restricted to a single focal length forces the filmmaker to think creatively about framing, and provided you’re using a “normal” focal length (about 35mm to 75mm FF equivalent), you can walk in or out to vary your perspective and still have natural-looking results.
Lately I’ve been using my Sony NEX-5n with a 50mm f/1.4 lens for my personal projects. The single-lens approach eliminates the need to bring a camera bag. Plus, the prime lens is lighter than a zoom and has a faster aperture, so I can bring it anywhere and shoot in any light.
Next time you go shooting for fun, try leaving the arsenal at home and using your feet to zoom instead.
