Nikon Z8 Burst Modes and Pre-Release Capture

Burst Performance in the Field

One of the most powerful capabilities of the Nikon Z8 for wildlife photography is its ability to capture fast image sequences using high burst rates.

For bird photographers, this is particularly important when photographing birds in flight, hunting behaviour or sudden movements such as take-off and landing.

The Z8 combines a 45.7 megapixel stacked CMOS sensor, the EXPEED 7 processor and support for high-speed memory cards. This allows rapid continuous shooting while maintaining autofocus tracking and subject detection.

Understanding burst modes, buffer behaviour and memory card performance is essential for getting the best results in fast-moving situations.

Understanding Burst Modes

The Z8 offers several continuous shooting modes that determine how quickly images are captured.

The most important mode for bird photography is Continuous High (CH).

Up to 20 frames per second in full-resolution RAW
Maintains full image quality and editing flexibility

At 20 fps, the camera captures subtle variations in wing position, movement and behaviour, increasing the likelihood of capturing the decisive moment.

Because the Z8 uses a stacked sensor and electronic shutter, these speeds are achieved without the mechanical limitations of DSLR cameras.

Higher frame rate options are also available:

30 fps (JPEG)
60 fps (DX crop mode)
Up to 120 fps in specialised high-speed modes

These can be useful in specific situations, but 20 fps RAW generally provides the best balance of speed and image quality.

Frame Rate and Bird Photography

High frame rates allow multiple frames to be captured during very short moments.

In bird photography, behaviour can change in fractions of a second. A take-off or direction change may happen too quickly to time precisely.

At 20 fps, the camera captures multiple frames within that moment, increasing the chance of recording the strongest image.

High burst rates are particularly useful for:

Birds taking off
Birds landing
Aerial hunting behaviour
Interactions between birds
Rapid changes in flight direction

Rather than relying on perfect timing, burst shooting allows selection of the best frame afterwards.

Understanding the Camera Buffer

During burst shooting, images are first stored in the camera’s internal buffer.

The buffer allows continued shooting while images are written to the memory card.

If images are captured faster than they can be written, the buffer will fill. When this happens, the camera may slow or pause briefly.

Buffer performance depends largely on memory card speed.

Memory Cards and Burst Performance

The Z8 includes two card slots:

CFexpress Type B / XQD
SD UHS-II

Both are supported, but performance differs significantly.

High-resolution RAW files are large, so card speed directly affects sustained burst performance.

CFexpress Cards

CFexpress Type B cards are designed for very high data transfer speeds and are the preferred choice for wildlife photography.

Advantages:

Extremely fast write speeds
Rapid buffer clearing
Reliable performance during long bursts
Strong support for high-resolution RAW capture

In practice, fast CFexpress cards allow longer sustained bursts before buffering becomes a limitation.

SD Cards

The Z8 also supports UHS-II SD cards.

Advantages:

Lower cost
Wide compatibility
Easy availability

Limitations compared to CFexpress:

Slower buffer clearing
Reduced sustained burst duration
Increased chance of buffering during long sequences

For general use, SD cards perform well. For intensive wildlife photography, CFexpress offers a clear performance advantage.

Why CFexpress Is Preferred

Bird photography often involves extended bursts during fast or unpredictable behaviour.

Examples include:

Birds taking flight
Diving or hunting behaviour
Aerial displays
Interactions between birds

Because CFexpress cards write data more quickly, they allow the buffer to clear faster and reduce interruptions.

Pre-Release Capture

Pre-Release Capture is one of the most useful features of the Z8 for wildlife photography.

When the shutter button is half-pressed, the camera continuously records images into a temporary buffer.

When the shutter is fully pressed, images captured both before and after that moment are saved.

This is particularly useful when photographing unpredictable behaviour.

For example, a bird taking flight may move before the photographer reacts. Pre-Release Capture ensures those earlier frames are still recorded.

Practical Use

A typical workflow:

Half-press the shutter while observing the subject
The camera begins buffering frames
Fully press the shutter when the action occurs
The camera saves frames from before and after the press

This significantly increases the chance of capturing the decisive moment.

Using Burst Modes Effectively

While high frame rates are powerful, they should be used selectively.

Very long bursts produce large numbers of images that require sorting during editing.

Many photographers prefer short, controlled bursts when behaviour suggests an important moment is about to occur.

Combining timing with burst capability provides the best balance between capture success and workflow efficiency.
