Mastering Field Macro: Godox MF12 Dual Flash on the Nikon Z8
Macro photography in the field is a balance of light, depth of field and careful technique. With a handheld Nikon Z8 and NIKKOR Z MC 105mm f/2.8 VR S, a compact twin-flash arrangement is far easier to manage than a large speedlight mounted on a bracket.
The Godox MF12 system brings two small flash heads close to the lens, allowing the direction and balance of the light to be controlled independently. With suitable diffusion, it is an effective setup for photographing insects, plants and other small subjects in natural surroundings.
Firmware C3.10 is current, and the MF12 specifications, including eight power levels and 0.01 to 1.7-second recycling, are correctly stated. Nikon firmware and Godox MF12 specifications.
1. Why the MF12 System Suits Field Macro
A large flash mounted high on the camera can make low-level macro work awkward. It adds bulk, alters the balance of the camera and can catch on surrounding vegetation when working close to the ground.
The MF12 system is different. Each flash head weighs approximately 144 g and mounts around the lens using Godox’s MF-AR adapter ring. The weight is still at the front of the lens, but the setup is considerably less top-heavy than a conventional flash-bracket arrangement.
Two flash heads also offer more control than a single frontal light. One can act as the main light while the other gently opens shadows, helping to retain shape and texture in a subject rather than producing an overly flat result.
The MF12 has eight manual output levels from 1/128 to full power, five groups, 32 radio channels and a quoted recycle time of approximately 0.01 to 1.7 seconds. It also has a built-in LED modelling light with ten brightness levels.
2. Basic Godox MF12 Setup
The Godox XPro II-N is an excellent trigger for the Nikon Z8, offering direct access to flash groups and output settings. The smaller X3-N also works with the MF12 system, but the XPro II-N is easier to adjust in the field.
Wireless setup
Set the XPro II-N and both MF12 units to the same wireless channel.
Set the same wireless ID on the transmitter and flash heads, or leave the ID set to Off on all units.
Assign one MF12 to Group A and the other to Group B.
Use Manual flash mode as the starting point. It gives consistent, repeatable output when the camera-to-subject distance remains broadly constant.
A useful starting balance is:
Group A: 1/32 power
Group B: 1/64 power
This gives one flash one stop more output than the other. Position the brighter unit to suit the subject and the direction of the available light. There is no fixed rule as to which side it should be on.
TTL can be useful when working quickly at changing distances, but Manual flash gives more predictable results for deliberate macro work and focus-stacking sequences.
3. Diffusion: AK Diffusers for the MF12
I now use a pair of AK Diffusers for the Godox MF12 twin-flash system. They provide a much larger, softer apparent light source than the small supplied caps.
This is particularly helpful with reflective subjects, including beetles, damselflies, hoverflies and dew-covered insects. The aim is to soften harsh specular highlights while retaining fine detail in the eye, wings and body texture.
The best flash-lit macro image should still feel connected to its surroundings. Use diffusion and modest power to reveal detail, rather than making the lighting itself the obvious subject of the photograph.
4. Nikon Z8 Settings for Field Macro Flash
Exposure Mode
Manual exposure is the simplest approach for consistent flash macro work. It allows the aperture, shutter speed, ISO and flash output to be set independently.
A sensible initial setting is:
Mode: Manual
Aperture: f/8
Shutter speed: 1/125 s to 1/200 s
ISO: 64 to 400, depending on the amount of ambient light required
Flash output: Begin around 1/64 to 1/32 and adjust after a test frame
ISO 64 is the Z8’s base ISO and provides its best dynamic range. However, a higher ISO is often sensible in the field if it allows a more natural background, lower flash power or a more practical working aperture.
Flash Sync Speed
Go to:
Custom Settings Menu → e1: Flash sync speed
Set this to 1/200 s for normal MF12 use.
The Z8 offers Auto FP High-Speed Sync with compatible flash units, but the MF12 does not list HSS as a feature. The fact that the XPro II-N transmitter supports HSS does not give the MF12 heads HSS capability.
For dependable MF12 output, keep the shutter speed at 1/200 s or slower.
Viewfinder and Monitor Display
Go to:
Custom Settings Menu → d9: View mode (photo Lv)
My preferred setting is:
Show effects of settings → Only when flash is not used
This preserves a useful preview of exposure and colour settings, while allowing the display to brighten for easier viewing when a flash unit is attached and ready to fire.
If your particular trigger setup does not give a workable preview, use:
Adjust for ease of viewing
This prioritises a bright, usable display, but it does not show the full effect of exposure, white balance and Picture Control changes.
MF12 Modelling Lights
The LED modelling lights are useful for positioning the flash heads, seeing a small subject and assisting manual focus. They may also help autofocus in poor light, but they are not powerful enough to guarantee autofocus performance in deep shade.
5. Technique A: Early-Morning Ambient Fill
Early morning often offers the best conditions for field macro. Insects can be less active, dew adds interest and the background usually retains more colour and atmosphere than it does in harsh midday sun.
The aim is to use flash as gentle fill rather than allowing it to overpower the scene.
Try this as a starting point:
Aperture: f/8 to f/11
Shutter speed: 1/100 s to 1/160 s
ISO: 64 to 200
Flash power: 1/64 or 1/128
The slower shutter speed allows ambient light to record in the background. The low-power MF12 output adds detail to the subject and, because flash duration becomes shorter at lower output, can help freeze minor movement.
Take a test frame and assess the image carefully.
If the background is too dark, lengthen the shutter speed or increase ISO. If the subject looks too bright or flash-lit, reduce the flash power or alter the angle and diffusion before changing everything else.
6. Technique B: Focus Stacking with the Z8 and MF12
Focus stacking is useful when one frame cannot provide enough depth of field across an insect’s head, thorax and wings. The Nikon Z8’s Focus Shift Shooting function automatically advances the lens focus through a sequence of images, ready to combine later in Helicon Focus or similar software.
The Z8 moves focus in preset steps. There is no need to turn the focus ring or deliberately move the camera forward during the sequence.
Preferred Method: Tripod-Based Focus Shift Shooting
A tripod is the preferred method for Z8 Focus Shift Shooting. It gives the camera a stable position, keeps framing consistent and gives the stacking software the best possible files to align.
It is particularly effective for a settled early-morning insect, a static plant subject or a carefully controlled macro composition.
Begin by focusing slightly in front of the nearest important point on the subject, usually the closest eye. The Z8 then moves focus away from the camera through the subject.
Go to:
Photo Shooting Menu → Focus shift shooting
Use these settings as a starting point:
Number of shots: 20 to 50
Focus step width: 3 to 5
Interval until next shot: Start at 1 second with flash, then reduce only after testing reliable recycling
First-frame exposure lock: On, if you want the camera exposure locked from the first frame
Focus position auto reset: On, if you expect to repeat another sequence at the same focus distance
The camera can record focus-shift frames at up to about 5 fps with the interval set to 00. Nikon recommends this setting for shooting without flash. When using the MF12 units, select an interval long enough for both flash heads to recharge fully at the chosen output.
At greater magnification, use a smaller step width and more images. Nikon recommends a step width of 5 or lower for stacking, as larger steps risk leaving gaps in focus.
Avoid unnecessarily small apertures. In close-up focus-shift work, apertures around f/8 to f/11 will often retain finer detail and reduce diffraction.
Handheld Focus Shift Shooting
Short handheld focus-shift sequences can be useful in the field when setting up a tripod would disturb a subject or mean losing the moment. Once the initial focus has been set, the Z8 moves focus through the selected preset steps, so there is no need to move the camera forward or turn the focus ring during the sequence.
This is a practical field technique rather than Nikon’s formal recommendation.
Nikon advises keeping the camera still during Focus Shift Shooting, so a tripod remains the most dependable option for a clean, easily aligned stack.
For handheld work, brace your elbows, hold a stable composition and keep the sequence short. Use low, consistent MF12 output and choose a shooting interval that allows both flash units to recharge fully.
Inspect the files before moving on. If camera movement, subject movement or inconsistent flash exposure has affected the sequence, a well-executed single frame is preferable to forcing an untidy stack.
7. Final Fieldcraft Checks
Before moving away from a subject, check:
The closest eye is sharp
Flash highlights are controlled rather than clipped
Both MF12 units have fired consistently
The background still contributes to the image
The sequence covers the required depth of the subject
Wind, stem movement or insect movement has not ruined the stack
The most successful field macro images come from patient observation and subtle lighting. The MF12 system, AK Diffusers and Nikon Z8 provide the control, but the final result still depends on careful positioning, a calm subject and an honest response to the light already present in the habitat.
Final Thoughts
The Godox MF12 twin-flash system is a compact and flexible lighting solution for Nikon Z8 field macro photography. Used in Manual mode, with thoughtful diffusion and restrained output, it can reveal fine detail without losing the natural feeling of the scene.
For single images, work slowly and let ambient light remain part of the composition. For depth-critical subjects, the Z8’s Focus Shift Shooting function, used from a stable tripod, provides the most dependable route to a clean, detailed focus stack.
