Photographers can be pretty geeky about lenses. I know I’ve eavesdropped on and occasionally participated in extended conversations that revolved almost exclusively around various types of lenses and their features — telephoto lenses, zoom lenses, vintage lenses, pancake lenses, lenses with built-in hoods, lenses with image stabilization, lenses with a max aperture of f/0.95. Glass is something photographers think about and talk about constantly. It makes sense I suppose, but how many lenses do you really need? I can’t answer that for you but I do know that regardless of how many lenses you own, you can only use one at a time. If you were to give one lens priority over all others, which would it be? Allow me to make a case for the humble 50mm lens (or its focal length equivalent). A 50mm Is Versatile And Easy To Travel With Whether you’re walking through your neighborhood or traveling abroad, a 50mm lens isn’t going to become a burden (unless it’s got a max aperture of f/1.2). A key advantage of the so-called “nifty fifty” lens is that it is relatively inexpensive, small and lightweight. And it’s versatile. You can spend an entire day with this one lens and capture any kind of photo you want, never worrying about having to carry multiple lenses and then stop to swap them in and out each time you encounter different types of subjects.
