>>4372712If you want to shoot with a handheld camera, my advice definitely changes.
If you don't want to use flash, you'll simply have to buy the best lenses you can afford (fast aperture/image stabilised/both) and just get good at focusing and holding still. You should always meter manually in low light when you're moving, as whatever light sources there are will always throw off auto exposure depending on which direction you're aiming/your composition. Meter off an object that's lit roughly normally for the scene, and decide how underexposed you think you can get away with, and just keep the settings the same until the light changes.
Lower your standards for what is acceptably sharp/exposed.
Expect to waste a lot of film.
