Jezz, I'm other anon who's 9 years into photography and In only shoot MF M. After first 10K of such frames you literally focus faster than AF and don't really find it hard to adjust exposition.
If anon wants to shoot manually, even from the beginning, just LET them instead of being a jerk. >>4287242
Your indoors and evening streetlight exposure settings are 800 ISO, f2, 1/60 pretty much always. Even if such a setup miss a stop or two, it will either work anyways or become a solid point to adjust in a right direction.
In sunlight consider using exposure meter. If your camera is THAT much of a crap it don't show this indicator, buy some cheap film-era external meter. Just don't selenium one, it's will be dead for sure. Or if you need to take a shot incredibly quick, 800 ISO, f22, 1/500.
