1. 50mm lenses have great image quality

Do you think a $200 50mm lens can outperform a thousand-dollar zoom? Of course, it can. And compared to your camera’s kit lens, you’ll find the difference to be night and day. Therefore, expect sharper photos with superior contrast and gorgeous background blur.

2. Background Blur

Even the cheapest 50mm F1.8 lenses produce amazing background blur. Background blur is useful for three reasons. First of all, mixing a blurred background with an in-focus subject creates a 3D-like effect for a punchier image.

Furthermore, you can use heavy blur to hide distracting background clutter such as litter bins and crowds. And finally, it just looks great.

Of course, you need an expensive lens, right? Well, as the old saying goes, ‘no’. Even my old hundred-dollar Nikon AF-D 50mm F1.8 lens melts backgrounds to goo.

3. 50mm lenses are great for shooting in low light

Many cheap 50mm lenses are great for shooting in the dark thanks to their large F1.8 apertures. A 50mm F1.8 can soak up almost 10 times as much light as your F5.6 kit lens. As a result, you can keep your shutter speeds high to avoid camera shake and motion blur whilst avoiding high image-degrading ISOs. Read What is ISO.

4. 50mm Lenses are compact

On its own, the affordable 50mm lens is small and lightweight. But it also makes for a perfect jacket-pocketable companion for large superzooms.

Of course, some 50mm lenses are absurdly expensive. But even the cheapest 50mm lenses punch well above their weight.

Both Canon and Nikon offer affordable 50mm DSLR lenses whilst Canon also offers the bargain basement RF 50mm F1.8 for its latest RF mirrorless mount.

When a 50mm is not a ’50’

On a full-frame camera, a 50mm lens captures a 47-degree angle of view. As a result, a 50mm is a great option for everyday photography.

However, mounting the same 50mm lens onto a camera will a smaller sensor will yield a smaller and narrower image. For example, mount a 50mm onto a camera with a smaller APS-C sensor, and your angle of view narrows to approximately 31 degrees. In other words, you end up with an angle of view much too zoomed-in for everyday photography.
