Well, it’s all about this:

And you need a fast enough lens with a “real” viewfinder if you want to see everything your subject can see.
And I don’t mean the viewfinder is always in focus or at full aperture, but in actual use I rarely have to adjust anything.
But you still need a camera with a fast enough f/number like 5.0 or above.
And you still cannot get good photos in low light without the use of a lens with some sort of built-in shutter feature.
As a minimum, a good lens with a small aperture to shoot at 120 is probably worth a look.

This has the widest aperture of any lens I know. And it offers the most depth of field of any lens on this list. As a general rule, in low light, I’ll
