2 stops.

I spent some time googling this + reading forum threads. It all got a bit too technical for me. Would anyone be able to give a simple, non-technical answer to this question:

If I shoot the same low-light event (concert etc.) with these two combos, how many stops do I gain with the Z6? Image stabilisation does not matter much since the subjects are moving.

Combo #1: Panasonic G9 + PL 35-100/2.8

Combo #2: Nikon Z6 + Nikon 70-200/2.8

I would love a really simple answer, something like "1/50s with #1 will look more or less like 1/125s with #2". I don't need a technically perfect answer, just a rough ballpark figure.

Unless I have misunderstood something, the two components involved in making the Z6 the better combo for low light is the sensor and the lens. I don't really understand the technical aspects of that, and I would prefer not to have to understand them either.

The DPR "comparometer" makes it look like about 2.5 stops:

Artificial light


But let's say 2 stops, since the difference seems more to be chroma noise, which may be an artifact of how the RAW converter deals with saturation for the different files.

The reason I'm asking is, I've been offered a used Z6 for 1,000 €, but I'm not sure I want to spend that much. I realise it's a good price for a Z6 mark I in good condition, but I'm not rich. Getting some decent glass for it would be so expensive...

Yeah -- it adds up, doesn't it? That said, the f/1.8S primes and f/4S zooms seem to be pretty good value for the money.

If I can get "good enough" results with something like the PL 35-100/2.8 or the Olympus 75/1.8 with my G9, I'm not sure I want to spend that much at this time.

Here's a good way to test: take a photo of the same scene two stops apart with your current setup. For example, shoot the same scene with the same exposure time at f/5.6 ISO 6400 and f/2.8 ISO 1600. If you prefer the f/2.8 photo overall (it will be less noisy but also have less DOF), then decide if the extra money for a Z6 setup is worth it for you. Otherwise, stick with what you've got.

Thank you

Hope that helps!
