Hi…
If you’re in low light, and can not use external lighting, you’ll have to use a high ISO. I try to avoid that, but it’s up to you. With low light, I try to stay with f1.4 to f2.0 and that means primes… I know, that can be a pain, but if you’re not run and gun primes are a good thing.
Happy Hunting!
