Prime lenses are commonly wide-angle lenses. When they discuss the best all around lens it’s usually in the range of 35mm. it’s good for portraits and landscape and street photography, an all in one all-purpose lens for all occasions. For me? I’m usually shooting at max tele on my zoom lens. I get rid of distracting background. I don’t have to move closer. It’s a good all-around lens for the lazy photographer. I don’t get the idea of 35mm. I can shoot at wide angle. My zoom allows. But I find most of my shots are near to max tele. It’s how it is.
