USE A FAST PRIME
a wide-aperture prime lens is a broadly useful optic for shooting handheld in low ambient lighting. even when scenes seem well lit by streetlights, the shutter speed at mid-range ISO settings can be surprisingly low. investing in a 35mm, 45mm or 50mm f1.4 will enable sharper shots when working unsupported.
