How Prime Lenses & Zoom Lenses Suit Your Needs
Do you carry around your camera everywhere? Yes/No
Okay, so you're a photo enthusiast who carries your camera everywhere. I wish I could do that, as I've seen some of the best photos from people who do this. It's all about capturing the moment by being at the right place at the right time. Having your camera with you at all times means that you need to cut out "accessory creep", where people carry every possible camera add-on they've got. You need great flexibility in shooting. Sometimes you're taking a candid capture of the cute kid enjoying an ice cream, the next moment your shooting that surfer riding the waves. You need a lens that can allow a wide shooting range. So, zoom lenses are the way to go! They offer the greatest flexibility in such instances.
How much money can you throw at your lenses? I can afford to spend more/ not very much
The pictures that you take primarily depends on the kind of lens that you use. The camera that you use is only secondary! So, if you're thinking about being on the conservative side when it comes to buying lenses then you need to sacrifice mobility and comfort. Zoom lenses are often pricier than prime lenses. The range of shooting ability and comfort of not having to carry a bunch of lenses or keep changing them comes at a price.
What's your style of photography?
You don't take a sword to a gunfight! Choosing the right lens mostly depends on the kind of photography you intend to shoot. Street photography, shooting sports, etc., where the subject is constantly displaced in space, means that you need to be able to adjust your focal length to get that perfect shot or expression. Furthermore, you need to able to capture that defining moment rather than fumbling for your lens in your camera bag and switching it! There is no better tool than a zoom lens for this task.
If your work involves more event photography or studio photography, then you've always got the option of switching lenses and reframing a shot without worry of missing the "prefect shot". Prime lenses are among the best portrait lenses. Shooting with a prime lens with a wide open aperture brings the essence of the face that you're shooting along with a wonderful bokeh. There is no doubt that this should be your choice.
