HERE’S A A LOWDOWN ON HOW TO CHOOSE DIFFERENT LENSES FOR DIFFERENT SITUATIONS AND DIFFERENT PHOTOGRAPHIC EFFECTS.
Amajor plus that a digital SLR (single-lens reflex) camera has over the compact is its ability to use different lenses. Today’s mirrorless compacts too can be fitted with lenses as required by the shooting but there are more options in DSLRS.
The lens—a photographer’s third eye— is the single-most important factor in the picture-making abilities of a camera. All lenses comprise a system of optics that direct the image on to the sensor (in film cameras, on to the film plate). You can use a variety of lenses from zooms with shifting aperture to fixed focal-lengths for different photographic situations.
One tip: When using zoom, restrict yourself to a 4X zoom, that is, if you are using, say, a 16-85 mm zoom, the best results will be between 16 mm and 65 mm.
