There are two types of lenses which I like to use: wide portrait lens for sharp look and manual lens for older cinematic, soft look for foggy effects. I like to mix both of them. Moreover, I like to use autofocus for fast-paced, street photography, and manual lens for portraits and settle moments. It's a mix between the old and the new stuff.
It doesn't matter whether the camera is big or small. Sometimes I know for a specific place it would be great if I had a shallow depth of field. But for spontaneous kind of shooting I would bring a light camera, so I can move around quicker. So I would say that it depends on a shoot itself.
