Sooo I feel u on the pulsing… saw this earlier but just now responding. I ran a similar setup for talking-head + handheld b-roll and my “kit zoom” was also *fine* until indoor light, then AF-C would do that tiny breathe/pulse thing and it drove me nuts.

In my experience, Reply #1 is right: newer native Nikon Z lenses tended to behave smoother for video AF (less chatter, quieter, fewer random background grabs). One small thing that helped regardless of lens was backing off AF speed/sensitivity a bit—kinda made transitions less twitchy and hid breathing. Lesson learned: lens choice matters, but the in-camera AF tuning is like 50% of the battle, honestly. cheers

Did this last week, worked perfectly

Sooo i had this exact “AF pulse indoors” thing on my Z6 II and went down the rabbit hole lol. Pro tip: check out Lensrentals + Dustin Abbott’s reviews—they usually call out focus breathing + video AF behavior in plain english. Market-wise, Sony/Canon have more “video-first” AF lens notes, but in Z land I’d compare Nikon NIKKOR Z 24-70mm f/2.8 S vs Nikon NIKKOR Z 24-120mm f/4 S before jumping to a prime… i think you’ll see the most real-world stability there. gl!

> “For Nikon Z video with reliable continuous autofocus, what lens would you recommend and why?” Not sure I totally buy that a lens swap is gonna be the big unlock on a Z6 II. Like, yes some lenses breathe less, but the “AF-C pulse / background jump” is usually body + settings + lighting more than optics. If you want a performance answer, I’d actually test it: set up a talking-head at your usual distance, put a bright object behind you, then record 2–3 min clips while you change (1) aperture, (2) face/eye on vs off, (3) AF-area mode, (4) AF subject tracking sensitivity, (5) frame rate/shutter. Then review at 200% and count how often it re-acquires. And honestly—add light. A cheap key light often reduces hunting way more than new glass.

Late to the thread but totally agree with Craig on the Nikon NIKKOR Z 24-70mm f/2.8 S. I had a similar headache doing a series of indoor interviews last winter in a basement studio with pretty dim lighting. My kit lens was just hunting way too much and that micro-pulsing was showing up in the final edit. Once I swapped to the f/2.8, the camera had so much more light to work with that the eye-detect just locked on and stayed there. It is heavy tho, which is the main downside for handheld stuff. Tbh if you really want to kill that focus breathing and get that locked in look for talking heads, you might also look at the Nikon NIKKOR Z 50mm f/1.8 S. I started using it for my main angle because the breathing is almost non-existent compared to the zooms. It is also way cheaper than the pro zoom. In my experience, the f/1.8 prime lets the AF-C system grab onto contrast much easier when things get dark, so you dont get that nervous look in the footage. It basically made my Z6 II feel like a different camera for video work. The zoom is better for b-roll variety, but for the static interview stuff, the prime is hard to beat for reliability.

For your situation, I’d lean toward Nikon’s newer native Z glass (especially the newer zooms) over older stuff or adapters—honestly the AF behavior tends to be smoother and quieter for video. Background: lenses can “pulse” because the AF motor + focus-by-wire tuning isn’t optimized for continuous video. Why it matters: it’s not just sharpness, it’s how the lens transitions and how much it breathes.

So yeah, I’d go with a modern Z zoom for talking-head + b-roll, and keep the kit lens as a backup. A fast prime can look amazing!! but it won’t automatically fix hunting, and DOF gets so thin indoors that it can actually make misses more obvious lol. If you can, rent before buying—some copies just behave better. good luck!

Just sharing my experience: I ran a Nikon NIKKOR Z 24-70mm f/4 S on my Z6 II for years and yeah… indoors it’d do that tiny AF-C pulse, especially on a talking head with meh light. I swapped around a bunch and what actually changed things for me was:

- Nikon NIKKOR Z 24-70mm f/2.8 S: smoother transitions + less “nervous” micro-hunting (also more usable at f/2.8 so the AF isn’t living at high ISO)
- Nikon NIKKOR Z 24-120mm f/4 S: underrated for b-roll… AF felt calmer than my kit lens, and it’s way better value than people admit
- fast primes (I used a 50): great look, but DOF got so thin I actually noticed more “oops” moments on face tracking

Also lowkey, a small continuous light helped more than I expected. cheers

Great info, saved!

Saved for later, ty!

Saw this thread last night and had to chime in because I totally get the frustration with that AF pulse! Honestly, before you drop a ton of cash on a new lens, you gotta be super careful about using cheap variable ND filters!! I bought a budget one last year and it completely killed the contrast, which made my camera focus go absolutely haywire in dim light. It was a total nightmare! I almost had a meltdown before I realized the filter was just muddying the sensor vision. Speaking of meltdowns, I spent way too much time this morning trying to find my car keys in my camera bag and ended up finding a half-eaten granola bar from like... three weeks ago. My van is basically a mobile storage unit at this point and it is honestly getting a bit gross lol. I really need to clean it out before my next shoot. But yeah, definitely check your filters and lighting first so you dont waste money!

Regarding what #6 said about "Sooo i had this exact AF pulse indoors..." - yeah, it definitely feels like a common hurdle with that specific body. Looking at what everyone has shared so far, there seem to be a few main takeaways:

• Native Z glass is basically the gold standard for avoiding that nervous AF-C behavior.
• Moving to a lens with a wider aperture helps the camera's AF system "see" better in dim light.
• Some folks think it might be worth tweaking your settings or lighting before assuming it's purely an optics issue. Just to narrow things down a bit tho...
• What kind of lighting are you usually working with? Are we talking dim living rooms or more of a controlled studio vibe?
• Do you really need the flexibility of a zoom for everything, or would you be open to a two-lens setup for different shots?
