Nikon Z5 vs Z6 II in 2026: Which Used Body Is Actually Worth Buying?

Here's the honest starting point: both of these cameras are legacy products. The Z5 launched in July 2020. The Z6 II followed in October 2020. The Z6 II was replaced by the Z6 III in June 2024, and the Z5 got its own successor, the Z5 II, in April 2025. So if you're shopping new, this comparison mostly doesn't apply to you.

But if you're shopping used, this is one of the best value decisions in the Nikon Z ecosystem right now. Both cameras are full-frame mirrorless, both take the same Z-mount lenses, and both regularly turn up on the secondhand market for well under $1,000. The question is which one to grab.

I'll give you the short answer up front: get the Z6 II if you can stretch the budget. The Z5 makes sense in one specific situation.

What you're actually choosing between

Used Z5 bodies sell for around $700 on average, based on verified sales data. Used Z6 II bodies run roughly $420 more than that. So the real question is whether that gap is worth it for your shooting situation.

On paper, the specs look similar: both are 24MP full-frame mirrorless bodies, nearly identical in size and weight. But the sensor designs are meaningfully different. The Z6 II uses a back-illuminated (BSI) sensor, which gathers light more efficiently and delivers better performance at high ISO. The Z5's sensor lacks that architecture. In practice, that matters most in low light, which is exactly where full-frame shooters expect an advantage.

The burst speed gap is significant if you shoot anything that moves. The Z6 II shoots at 14 fps. The Z5 shoots at 4.5 fps. If you're photographing kids, dogs, birds, or anything that doesn't hold still, the Z5 will frustrate you.

Video is another clear split. The Z5 crops 4K footage by 1.7x, which effectively eliminates your wide-angle options and produces footage that looks contrast-heavy compared to native 4K. The Z6 II shoots cleaner 4K and supports 4K/60p. If video matters at all to your workflow, the Z5's video capability is genuinely limited.

Nikon Z5 (used)

What's good

It's a real full-frame mirrorless camera for around $700. That's a genuinely compelling entry point into the Nikon Z ecosystem, and it gives you access to every Z-mount lens Nikon makes. Image quality in good light is excellent. The body is solid, well-built, and comfortable to shoot for long sessions.

What's bad

The 4.5 fps burst speed is slow enough to be a real limitation in many shooting scenarios. The 4K crop is significant and the footage quality shows it. The non-BSI sensor means you'll notice the gap versus the Z6 II once ISO climbs past 3200 or so.

What's missing

4K/60p. A faster processor. The dual Expeed 6 setup that gives the Z6 II its performance headroom. If autofocus tracking is your priority, the research consensus as of 2026 is that both cameras are roughly similar here, but the newer Z5 II has a meaningful edge on both, having inherited the improved autofocus from the Expeed 7-based cameras.

What's good

The BSI sensor is the biggest practical upgrade over the Z5. Low light performance is meaningfully better, with an ISO range extending to 51,200 (expandable beyond that). The dual Expeed 6 processor gives it more processing headroom. And 14 fps burst speed makes it a camera you can confidently point at anything that moves. The cleaner 4K video makes it genuinely useful for hybrid shooters.

What's bad

It costs more used than the Z5, obviously. And by 2026 standards, it's an older body competing with significantly more capable cameras at similar used price points from other systems.

What's missing

The Z6 III's partially-stacked sensor and substantially better autofocus. If you need those, you're looking at early used Z6 III units at around $2,200, which is a very different budget conversation. The Z6 II also lacks the modern subject recognition autofocus improvements that came with Expeed 7.

Who should buy the Z5

One type of shooter, basically: someone who shoots landscapes, portraits, or other mostly static subjects, shoots in decent light most of the time, doesn't care about video, and wants the cheapest possible full-frame Z-mount body to start building a lens kit. At around $700 used, the Z5 is a legitimate way into full-frame Nikon. If that's your situation, it works.

For everything else, the Z5's limitations will show up quickly.

Who should buy the Z6 II

Most people looking at this comparison. The Z6 II is the better camera across the scenarios that matter most to enthusiast shooters: low light, action, video, and general versatility. The BSI sensor and 14 fps burst alone justify the price difference for a lot of shooters. And as a used body, it still delivers excellent image quality with a lens selection that keeps growing.

One more option worth knowing about

If your budget can stretch to around $1,700, the new Z5 II changes the equation. It brings Expeed 7-based autofocus improvements, which put it ahead of anything the Z5 or Z6 II can do, and it's a genuinely current camera with active firmware support (version 1.11 as of May 2026). For a lot of the buyers researching this comparison, the Z5 II might actually be the right answer, even if it means saving a bit longer.

Final recommendation

Buy the used Z6 II. The $420 premium over the Z5 buys you a BSI sensor, real burst speed, and usable 4K video. For anyone shooting in mixed conditions, any subject that moves, or with any interest in video, that's a real-world performance gap that shows up in your actual photos and footage.

Save for the Z6 II. You'll keep it longer. The Z5 earns its place only for shooters focused on static subjects in good light who are working with a hard budget ceiling — and even then, it's worth knowing the Z5 II exists before you commit.
