As said by George Holden, pancake lenses can be the ideal street photography lens for those who enjoy smaller camera setups. It’s not always necessary to pack a large zoom lens or even a fast aperture prime, because in street photography often including more of your image in focus is a preferred way to shoot. The compact size of a lens like this Sony 20mm f/2.8 means you never need to worry whether or not you can fit your camera kit in a bag or jacket pocket.
