There is a saying among gun owners. “Guns don’t kill people. People kill people with guns.”
This slogan is an ideal analog to what I often see when people buy a new lens like the marvelous and under-recognized 50mm f/1.8. “Lenses don’t make pictures. People make pictures with lenses.”
This lens has earned it the nickname “Nifty Fifty” over the years because it is affordable and capable of delivering beautiful results. But…
Any lens is a tool, and if you use a tool wrong, it won’t give you the results you want. All lenses are the same at f/11 in midday sun with your knees locked. A 50mm f/1.8 and an 18-55mm kit lens are the same at f/11. You might as well shoot with your phone or a point-and-shoot.
Taking advantage of tools like large-aperture lenses requires aggressive techniques, including moving yourself and using those large apertures. You didn’t buy an f/1.8 or f/1.4 lens to shoot it in Program mode or worse, green box mode, and have the camera choose every mediocre compromise it can.
So if you find yourself with a nifty little 50mm in your hands, take it to the limits – get close, shoot wide open, see the light. Only then can you discover why a lens like this is a great tool.
