In recent years, zoom lenses have been taking over the hearts of many working professional photographers as the more obvious, versatile choice. With the latest image sensors producing amazing quality, even at extremely high ISOs, it makes sense why more people have been leaning towards the convenience of zoom lenses. Zoom lenses have also gotten impressively sharp – most, even some cheap kit lenses, are sharp enough for day-to-day needs and also boast effective image stabilization systems. Some of the modern pro-grade lenses offer image quality that matches or even surpasses primes lenses in the same focal range. Despite all this, prime lenses haven’t really lost their desirability. Lens manufacturers such as Nikon and Canon have been rapidly updating and expanding their lens arsenal with new and better choices. Third-party manufacturers like Sigma are stepping into the game with confidence. Thanks to this, choosing between a zoom and a prime lens is now harder than ever. In this beginner guide, I talk about prime vs zoom lenses in detail, explaining their differences, along with some image samples.
1) What is a Prime Lens?
A prime lens is a lens with a fixed focal length (also commonly referred to as a “fixed lens”). What this means is that such a lens has a set angle of view which can not be changed – unless you move, you can not make the image appear larger or smaller within the frame. The only way of enlarging your subject and making it fill more of the frame is by physically getting closer to it. In turn, the only way to fit more into the frame is to step back.
