Because you want a lot of variety in your picture sets, you'll constantly be moving in and moving out and this is a lot of work and will wear you out quickly. A zoom lens will allow you to zoom in for your closeup shots and zoom out for your full length shots and although you may still have to move around a bit - it won't be nearly as hard as shooting with a standard lens. The trade off is that a stardard lens usually has sharper glass with better contrast but unless your shooting super high-quality material - just about any zoom lens on the market will work for your needs.
