Sony ZV-1 Low Light Settings: ISO, Stabilization, Noise

The Sony ZV-1 does its best low light work when you keep the lens at its widest aperture, put a cap on ISO AUTO, and let the built-in stabilization steady your hands. Sony's help guide lists ISO 200 to 25600 for stills and ISO 125 to 12800 for movies, and Videomaker's review found noise becomes noticeable at around ISO 1000 while the image stays usable up to ISO 12800.

What the ZV-1 brings to a dark room

Before you change a single setting, it helps to know what the camera has to work with. Videomaker describes a 20.1 megapixel 1.0-type CMOS sensor paired with a wide-aperture Zeiss lens and a BIONZ X image processor. PetaPixel lists the lens as a 24-70mm f/1.8-2.8, the same one used on the RX100 III, IV and V (A).

Think of the sensor as a bucket left out in the rain. A bigger bucket catches more drops, and a bigger sensor catches more light. Sony points out that the Type 1 sensor in the ZV-1 series is much bigger than a smartphone's and can capture footage in low light. It is still smaller than the sensors in many interchangeable-lens cameras, so it pays to help it along with good settings.

Feature	Sony ZV-1	Source
Sensor	20.1MP 1.0-type CMOS
Lens	24-70mm equivalent, f/1.8-2.8
Stills ISO	ISO AUTO or ISO 200 to 25600
Movie ISO	ISO 125 to 12800
Stabilization	Optical, in the lens
Video	4K up to 30fps, 1080p up to 120fps
Flash	None

That last row matters at night. The ZV-1 has no flash, so you have to rely on available light, your settings, or a lamp you bring along.

ISO limits on the ZV-1

ISO is like a volume knob for light. Turn it up and a dark scene gets brighter. Sony's help guide says the larger the ISO number, the higher the sensitivity. The catch is that the help guide also says the higher the ISO value, the more noise will appear in your images.

Noise looks like sand sprinkled over your picture. Picture a radio turned up loud: you hear the music better, but you also hear more hiss. That is what high ISO does to an image.

Photo and video ranges are different

Sony's help guide lists ISO AUTO or ISO 200 to ISO 25600 when you pick a value for stills. For movies, ISO 125 to 12800 is available. If you set a value below 125 for video, the camera switches to 125 while recording and goes back to your original setting when you stop.

The help guide adds that the available ISO settings differ between stills, movies and HFR, the high frame rate slow motion mode. The range also changes depending on the Gamma setting under Picture Profile. So if you cannot reach the ISO number you want, check which picture profile is active before assuming something is broken.

One more detail from Sony: below ISO 125, the dynamic range may decrease. Dynamic range is how much of a scene the camera can hold at once, like seeing both the dark inside of a room and the bright window without either one turning to pure black or pure white.

Put a ceiling on ISO AUTO

ISO AUTO lets the camera choose the number for you, which is handy when light keeps changing. The smart move is to tell it how high it is allowed to go. Sony's help guide explains that you select ISO AUTO, press the right side of the control wheel, and set values for ISO AUTO Maximum and ISO AUTO Minimum. Those values also apply when you shoot in ISO AUTO under Multi Frame NR.

When the camera is in P, A, S or M mode with ISO AUTO selected, it adjusts ISO within the range you set. This is a great halfway step out of full auto. You choose the aperture or shutter speed, and the camera handles ISO inside limits you trust.

Where noise starts to show

In Videomaker's informal testing, noise became noticeable at around ISO 1000, and the image was usable up to ISO 12800. A sensible starting ceiling sits near the point where noise first appears. Raise it only when the scene is too dark and you have already opened the aperture all the way.

Videomaker also tried the high frame rate mode on small fireworks and saw noise in the image, which the reviewers thought might have been made worse by leaving the camera in auto exposure. That is a helpful lesson for you: when the light is tricky, taking control of your settings gives you a better shot at a clean picture.

Shutter speed: the door that lets light in

Shutter speed is how long a little door stays open to let light reach the sensor. Leave the door open longer and more light gets in, so the picture gets brighter. Leave it open too long and anything that moves, including your own hands, turns into a smear.

The ZV-1 has no mode dial, but all the regular shooting modes are still there through a Mode button. In S mode you pick the shutter speed and the camera picks the rest. In M mode you choose everything yourself.

For low light, a simple order of steps keeps things sharp:

• Open the aperture first, because it adds light without adding blur or noise.
• Slow the shutter only as far as you can hold steady, or as far as your subject's movement allows.
• Raise ISO last, and keep an eye on noise.

If shutter, aperture and ISO still feel like a puzzle, the exposure triangle guide walks through how the three settings work together with simple examples. Getting it wrong a few times is normal. Every blurry test shot shows you where your limit is.

Stabilization: SteadyShot and Active

Stabilization helps when your hands wobble, which happens more at night because you are often using a slower shutter. PetaPixel lists optical image stabilization among the ZV-1's standout features. One PetaPixel reviewer noted that the lens stabilization made handheld shooting fairly steady.

You change the movie stabilization under MENU, then Camera Settings2, then SteadyShot, then your chosen setting.

Standard versus Active

Sony says SteadyShot Active is up to 11x better than standard stabilization, according to Digital Camera World. There is a trade-off. PetaPixel's reviewer found that Active stabilization crops in slightly, which made the 24mm wide end too tight for vlogging.

Reviewers had mixed results. Videomaker tested the stabilization on a brief walk and said it worked well enough. Digital Camera World's run and gun tests came out jerky, and the reviewers suggested Sony's VPT2BT grip or a gimbal, adding that the ZV-1's light weight means you would not need an expensive one.

Keep in mind that stabilization steadies your hands. It cannot freeze a person walking past at a slow shutter speed. For moving subjects in the dark, you still need a faster shutter, a wider aperture or a little more ISO.

Choosing between ZV-1 models

If you are still shopping, stabilization and aperture differ across the ZV-1 family.

Model	Lens	Optical stabilization	ISO range listed
Sony ZV-1	24-70mm f/1.8-2.8	Yes	200 to 25600 stills, 125 to 12800 movies
ZV-1 Mark II	18-50mm f/1.8-4	No	Not listed in these sources
ZV-1F	20mm f/2	Not listed in these sources	125 to 12,800

PetaPixel notes the ZV-1F's sensor uses only contrast-based focusing, with no phase detection. For low light handheld work, the original ZV-1's lens stabilization is a real point in its favor.

Lens and aperture tricks for dim rooms

Aperture is like the pupil of your eye. In a dark room your pupil opens wide to let in more light, and a lens does the same thing. The smaller the f-number, the wider the opening.

The ZV-1's zoom goes from f/1.8 to f/2.8 across its 24-70mm range. That means it lets in the most light at the wide end. When the light drops, zoom out and step closer to your subject instead of zooming in.

The camera has a shortcut for this. PetaPixel describes a Background Defocus mode that opens the aperture all the way at the press of a button. Videomaker notes it has a dedicated switch. It is sold as a blurry background tool, but in dim light it is also a quick way to grab the brightest aperture.

PetaPixel also lists a variable neutral density filter among the ZV-1's features. An ND filter works like sunglasses for the lens. Sunglasses are great at noon and unhelpful at night, so make sure ND is not darkening your picture when you are already short on light.

Keeping noise under control

Noise is not a failure. It is the camera telling you it needed more light. A few habits help:

• Add light when you can. A lamp, a window or a store front can lower the ISO you need.
• Take control of exposure. Videomaker suspected auto exposure added to the noise in its fireworks clip.
• Shoot RAW for photos. Digital Camera World notes the ZV-1 shoots RAW files, which help with highlight recovery.
• Get video exposure right in camera. The ZV-1 records 8-bit video, not 10-bit, so you have less room to brighten a dark clip later.

PetaPixel points out that a typical vlog can move from an overexposed scene to an underexposed one in seconds. For that kind of shooting, the ZV-1's Face Priority auto exposure is designed to give smoother transitions in shifting light.

Clean sound for night vlogs

Low light shoots often happen in noisy places like restaurants, streets and events. The ZV-1 has an on-board directional 3-capsule mic designed to capture what is in front of the camera while cutting background noise. A PetaPixel writer found the front-facing-only design frustrating when talking from behind the camera.

The camera has a 3.5mm mic jack and a Multi-Interface hot shoe, so you can add an external microphone. If you want a small wireless option to plug in, this is one to look at:

A simple low light starting setup

Use this as a first try, then adjust based on what you see on the screen:

1. Press the Mode button and choose A mode for photos or a manual video mode.
2. Zoom to the wide end so the lens can open to f/1.8.
3. Set ISO to ISO AUTO and choose an ISO AUTO Maximum you are comfortable with.
4. Turn on SteadyShot, and use Active only if you can accept a slightly tighter frame.
5. Check that the ND filter is not cutting light you need.
6. Shoot RAW for stills so you have more room when editing.

Take a few test shots, zoom in on the screen, and look at the shadows. If you see sand, find more light or open up before you push ISO higher.

Using a different Sony camera?

The same ideas apply across Sony's lineup, but the numbers change. For the interchangeable-lens models, read the ZV-E10 low light and night photography settings guide or the ZV-E10 II low light settings guide. For shutter speed and frame rate choices on the ZV-E10, see the ZV-E10 video settings guide.

If you shoot an a6700, the a6700 low light settings guide covers night work, and the a6700 autofocus guide helps when focus struggles in the dark. FX30 owners can start with the FX30 video settings guide.
