Focus Shift Shooting
G button U C photo shooting menu
Focus shift automatically varies focus over a series of shots. Use it to take photos that will later be combined using focus stacking to create a single picture with increased depth of field. Before using focus shift, choose a focus mode of AF‑S or AF‑C and a release mode other than self-timer or high-speed frame capture +.

Focus Shift Photography
- Take a test shot at current settings.
We recommend using one of the following power sources to prevent loss of power while shooting is in progress:
- A fully-charged battery
- An optional EH‑7P charging AC adapter
- An optional EH-8P AC adapter connected using the supplied UC‑E25 USB cable (featuring Type C connectors at both ends)
Focus.
- During focus shift, the camera takes a series of shots starting from a selected focus position and continuing toward infinity. Given that shooting ends when infinity is reached, the starting focus position should be slightly in front of (i.e., closer to the camera than) the closest point on the subject.
- Do not move the camera after focusing.
Highlight [Focus shift shooting] in the photo shooting menu and press 2.
Adjust focus shift settings.
Choose the number of shots.
- The maximum number of shots is 300.
- We recommend taking more shots than you think you’ll need. You can winnow them down during focus stacking.
- More than 100 shots may be required for photographs of insects or other small objects. On the other hand, only a few may be needed to photograph a landscape from front to back with a wide-angle lens.
Choose the amount the focus distance changes with each shot.
- Press 4 to reduce the focus step width, 2 to increase.
- Note that high settings increase the risk that some areas will be out of focus when the shots are stacked. A value of 5 or less is recommended.
- Try experimenting with different settings before shooting.
Choose the interval until next shot.
- Choose the interval between shots, in seconds.
- To ensure correct exposure when using a flash, choose an interval long enough for the flash to charge. A setting of [00] is recommended when shooting without a flash.
Enable or disable first-frame exposure lock.
- [OFF] is recommended if lighting and other conditions will not change during shooting, [ON] when photographing landscapes and the like under variable lighting.
- Selecting [ON] locks exposure at the value for the first shot, ensuring that all photos have the same exposure. Large changes in subject brightness during shooting may however result in apparent variations in exposure. This can be addressed by selecting [OFF].
Choose whether to use the electronic shutter.
- The volume of the sound made when the electronic shutter is released can be chosen using [Volume].
Choose whether the focus position returns to the starting position at the end of each sequence.
- We recommend selecting [ON] when using focus shift to photograph subjects at the same focus distance multiple times in succession.
- If [OFF] is selected, focus will remain fixed at the position for the final shot in the sequence.
Choose starting folder options.
Highlight [Start] and press J.
- Shooting starts after about 3 s.
- The display turns off during shooting.
- The camera takes photographs at the selected interval, starting at the focus distance selected at the start of shooting and progressing out toward infinity by the selected focus step distance with each shot.
- Shooting ends when the selected number of shots has been taken or focus reaches infinity.
Ending Focus Shift Photography
To end shooting before all shots have been taken, either:
- select [Focus shift shooting] in the photo shooting menu, highlight [Off], and press J, or
- press the shutter-release button halfway or press the J button between shots.
The memory card access lamp flashes between shots.
Cautions: Focus Shift Photography
- The shutter speed and the time needed to record the picture may vary from shot to shot. As a result, the camera may be unable to take shots at the selected interval.
- Shooting ends when focus reaches infinity, and consequently depending on the focus position at the start of shooting, shooting may end before the selected number of shots has been taken.
- If [ON] is selected for [Electronic shutter options] > [Electronic shutter], the shutter will sound with every shot unless [Volume] is set to [0] (note that this applies even when [ON] is selected for [Silent mode] in the setup menu).
- Regardless of the option selected for Custom Setting c3 [Power off delay] > [Standby timer], the standby timer will not expire while shooting is in progress.
- If you are using a flash, choose an interval longer than the time needed for the flash to charge. If the interval is too short, the flash may fire at less than the power needed for full exposure.
- If shooting cannot proceed at current settings, for example because shutter speed is set to “Bulb” or “Time”, a warning will be displayed.
- Changing camera settings while focus shift photography is in progress may cause shooting to end.
Focus Shift Photography: Restrictions
Focus-shift photography cannot be combined with some camera features, including:
- video recording,
- long time-exposures (“Bulb” or “Time”),
- the self-timer,
- high-speed frame capture +,
- bracketing,
- multiple exposures,
- HDR overlay,
- interval-timer photography,
- time-lapse video recording, and
- pixel shift.
Given that pictures shot at very small apertures (high f-numbers) may lack definition, we recommend that you choose apertures wider (f-numbers lower) than f/8–f/11.
Because focus depth is reduced at short focus distances, we recommend choosing smaller focus steps and increasing the number of shots when photographing subjects close to the camera.
