What mm lens is best for portraits?
For portrait photography, 50mm lenses are great for full-length and waist-level portraits, both on location and in the studio. This is thanks to the wide field of view compared to an 85mm or 135mm lens, and you don’t need to be too far away from the model to achieve these crops.
