Use a prime lens for better creativity
A prime, or fixed lens does a few things to help your photos. Not having zoom will force you to get up and move around, increasing the likelihood that you’ll find a new or creative perspective. Using a prime lens also makes you consider your framing more since you’ll be forced into situations where there will be obvious things you want to include or remove from the frame. Finally, fixed lenses are usually faster and aren’t confined to aperture limitations at various focal lengths.
