Is the fujifilm gf 30mm f 5 6 t s good for street photography?
Not really, in my view. The Fujifilm GF 30mm f/5.6 T/S is a manual-focus tilt-shift lens made for architecture and landscape. It frames like a 24mm on full frame, which is a useful wide view, but manual focus and the tilt-shift movements are built for slow, deliberate work, not quick shots on the street.
For street, the Street page says what matters most: a camera people don't notice, and one you can shoot without thinking. Small and quiet beats megapixels every time. The Landscape page explains why this lens suits the slower work it was designed for.
