If you go street photography what would you prefer and why: 1. Big and powerful SLR with a big top class zoom (D5 + 24-70/2.8). You have many keepers but attract attention like a big pro (!) 2. Medium size RF or mirrorless with a manual prime (Leica M10 + 35/1.4 or Sony A7ii + 35/1.4 or 50/2 (50/1.4) etc. . You use zone focus. 3. Snappy and small AF camera with a small lens (Olympus E-M5 Mk2 + Sigma 30/1.4 Contemporary or 25/1.8 etc).
