When you're just starting out in photography, one of the first things you'll probably wonder about is the difference between prime and zoom lenses. Check out this helpful video that details the characteristics, advantages, and disadvantages of both types.
Many photographers (particularly wedding and portrait pros) swear by prime lenses, which, simply put, are lenses that have a fixed focal length. When you're first starting out, there is a tendency to think that zoom lenses offer you a bunch of extra focal lengths, so why would you ever want to buy a prime lens? This helpful video from e6 Vlogs details why you might want to consider one. In my opinion, while there are advantages such as weight, light-gathering ability, and thinner depth of field, I really think that prime lenses are best for beginners, because the inability to zoom forces one to think about composition much more, and you quickly begin to appreciate the different looks offered by different focal lengths. I also think primes are just more fun to shoot with.
