Ask Corey: Best Mirrorless Camera for Low Light

Hi Corey

I am in a dilemma and really hope you can help me please.

The question I pose is simple – Z6 or Z7?

As a cave photographer who shoots say 90% of the year underground for magazines, I rely on a sensor with top-end low light capabilities, this is high up on the must have list. I currently use a D850 and absolutely love it. However, it’s big and the mirrorless system is too tempting.

Hi Robbie, one thing I’d point out before discussing the Nikon Z cameras is that the D5 is superior to the D850 in low-light. In fact, of all the Nikon cameras, the D5 rules the roost for its low-light performance and capabilities.

But, that’s not what you’re asking. I’m sure that if you’re squeezing through claustrophobic tunnels miles below the surface of the earth, having a smaller-factor camera could end up being a really enticing idea.

There’s not too much to say here. Your question was simple, and so is my answer. The Z 6 is the best low-light camera, surpassing the performance of the Z 7 as well as the low-light performance of your D850. The Z 6 is my favorite camera right now specifically for its speed. I think that going with the Z 6 will be an upgrade over the D850 for you, and more than anything I know you’ll really love the size when you’re burrowing underground.

If you’re not sold on the Z system yet, I’d be remiss not to point out that Nikon has also released the Z 50, a DX cropped-sensor rig that offers a way to break into the world of mirrorless cameras at a better price point. (Plus, you can try the Z 50 worry-free for 30 days with the Nikon Yellow Program.) That said, I can’t speak to the Z 50’s low-light performance, though I will say this: Like anyone adopting new technology, I was a bit of a skeptic when I started using Z cameras but now I admit that I can’t go back to the world of DSLR. I suspect you’ll be the same! Good luck with your journey.
