The cheapest sharp lens most brands sell, tested across portraits, street, and low light.
The nifty fifty has been the standard first-upgrade lens for decades, and after a month of shooting one on assignment it is easy to see why. For roughly the price of a kit accessory you get a lens sharper than most zooms, a wide f/1.8 aperture that blurs backgrounds beautifully, and a light body that never leaves your bag at home. On a full-frame body it sees roughly what your eye does, which makes composition feel natural.
It is not flawless. Autofocus on the budget versions can hunt in dim light, there is no image stabilization, and the fixed focal length means you zoom with your feet — a problem in tight rooms. But those limits are also a teacher. Working with one focal length forces you to move, to anticipate, and to think about framing before you raise the camera. The image quality you get in return, especially wide open at night, embarrasses lenses that cost five times as much.
Add your own verdict here: which situations it nailed, where it frustrated you, and whether you would buy the budget version or spend up for the faster one.
