What else to do need besides the included items when purchasing?


The GR IV has approximately 53 GB of built-in memory.
If you want to store more images, please prepare a memory card with a capacity suitable for the number of images you plan to shoot.
What material is used for the body’s exterior parts?


They are made of magnesium alloy.
Does the camera have a built-in optical viewfinder?


No, it does not. Optional external viewfinders (GV-1 / GV-2) are available.
Does the camera have a zoom function?


No, it does not have either an optical zoom function or a digital zoom function.
*It has a “crop” function that allows you to set the angle of view to 35mm or 50mm equivalent, in addition to the standard 28mm equivalent (35mm format conversion).
What is the crop function?


The crop function works by cutting away the outer area of the normal shooting range, resulting in a narrower angle of view. This makes it possible to shoot as if using a longer focal length. Although the camera is equipped with a fixed focal length lens, the crop function allows you to switch angles of view according to your subject, expanding your range of expression.

・This can be set in the Still Image menu under “4: Recording Settings” > “Trimming” Selecting ‘35mm’ or “50mm” will change the angle of view from 28mm equivalent to 35mm equivalent or 50mm equivalent. (35mm format equivalent).






When the [Crop] function is set, the available JPEG recording sizes are limited.

Crop Setting Off
(28mm)
Follows selected JPEG size
35mm [L] setting: recorded in [M].
[M], [S], [XS] settings: recorded according to the selected JPEG recording size.
35mm [L] or [M] settings: recorded in [S].
[S] or [XS] settings: recorded according to the selected JPEG recording size.
- Values are based on 35mm format conversion.

・You can assign the [Crop] function to the Fn button in the still image menu under [2: Operation Custom Setting] → [Fn Button Setting]. Once set, you can switch the angle of view simply by pressing the Fn button, without navigating the menu.





What is the angle of view when using the crop function, and what is it when the Wide Conversion Lens is attached to the GR IV?


■GR IV (Single Unit)
・ No Crop: 75.2°
・ 35mm Crop: 63.3°
・ 50mm Crop: 46.7°

■GR IV + Wide Conversion Lens (GW-4)
・No crop: 91.5°
・35mm crop: 78.8° (35mm equivalent: 26mm)
・50mm crop: 59.8° (35mm equivalent: 38mm)

Notes:
•All values represent diagonal angles of view.
•When using the Wide Conversion Lens (GW-4), the Lens Adapter (GA-3) must be attached.
Does the camera have image stabilization?


Yes. It has a 5-axis, 6-stop Shake Reduction system using a sensor-shift method. You can turn it on or off in the still image menu under [6: Shooting Assist Menu] → [Shake Reduction].





・When the self-timer is set to 2 seconds or 10 seconds in Drive mode, the Shake Reduction function automatically turns off.
To keep the Shake Reduction function on while using the self-timer, set the “SR Auto Off” option in the 6: Shooting Assist Menu under the Still Image Settings menu to “Do Not Auto Off”.




・The Shake Reduction on/off function can be assigned to the Fn button in still image mode. In the Menu Custom Setting → [2: Operation Custom Setting] → [Fn Button Setting], assign Shake Reduction to the Fn button. Once set, you can turn Shake Reduction on or off simply by pressing the Fn button, without navigating the menu.

- When the battery is fully depleted, the charging time is approximately 2.5 hours at 25°C.
- This charging time is for reference only and may vary depending on usage conditions.
- The actual charging time depends on the remaining battery level.
- If the battery has been left in the camera for a long period and becomes over-discharged, charging with a device other than a computer will be required.
- When connecting the camera to your computer via the USB cable, the camera will start up in playback mode.
After connecting, turn off the camera’s power to begin charging.
The camera’s status lamp will light up, indicating that charging has started. When the status lamp turns off, charging is complete.

Can the light intensity of the external flash GF-2 be adjusted from the camera?


No, it cannot.
Is manual flash available with the optional external flash GF-2?


Manual flash can be used when the camera’s shooting mode is set to M, with flash output at 1/1 or 1/4.
Manual flash settings can be configured in Menu → Still Image Settings → 2: Exposure Settings → Flash Mode → Flash Output. You can set it to AUTO, 1/1, or 1/4.





What is the guide number and flash sync speed when using the optional external flash GF-2?


The guide number is 3 (ISO 100).
At ISO 400, the guide number is 6, and at ISO 1600, it is 12.
When using the GF-2, flash sync is possible up to a shutter speed of 1/2500 sec.

Note: Please take the following into consideration when shooting.
Depending on the shooting conditions and the subject, the image may gradually become darker as the shutter speed increases. This occurs because the flash duration is longer than the time the shutter is open.
If the image appears dark even when the flash fires at high shutter speeds, use a slower shutter speed.
Do not fire the flash directly in front of or near a person’s eyes during portrait photography, as this may cause eye injury. Pay special attention with infants.
What are the features of the optional external flash GF-2?


Its ultra-compact design makes it easy to carry.
In terms of functionality, when the camera is set to ISO AUTO, it supports automatic flash control, where the camera adjusts the guide number and ISO sensitivity according to the distance to the subject.
Can the optional external flash GF-2 be used in HS mode (High-Speed Sync mode)?


The flash does not support High-Speed Sync mode, but flash sync is possible up to a shutter speed of 1/2500 sec.
Is the optional external flash GF-1 supported?


Since there is no linking function, please use the GF-1 as a camera other than the R type described in the GF-1 user manual, either with Auto External Flash or Manual Flash.
Are Macro Strobes (Auto Macro Flash) AF160FC or AF140C supported?


They cannot be used because there is no linking function.
Although it may be physically attachable with certain adapter combinations, proper exposure may not be achieved, so usage is not supported.
Are Auto Flashes AF180FG or AF201FG supported?


They cannot be used because there is no linking function.
Although they can be attached, manual flash using the flash unit’s M (FULL) and M (1/4) settings is possible. However, proper exposure may not be achieved in P-TTL, so usage is not supported.
Note: The Flash Mode cannot be set. The flash always operates in Fill Flash mode.
Are Auto Flashes AF540FGZ II and AF360FGZ II supported? Can they be used for wireless shooting?


They cannot be used because there is no linking function.
Although they can be attached and manual flash is possible. However, proper exposure may not be achieved in P-TTL, so usage is not supported. Wireless shooting is not possible.
Note: The Flash Mode cannot be set. The flash always operates in Fill Flash mode.
What are the program lines?


When the exposure mode is set to P (Program AE), you can choose from the following three program lines that determine the exposure.

Normal The camera automatically selects the shutter speed and aperture that achieve standard exposure.
Depth Priority (Shallow) Within the combination of exposure values that achieve standard exposure, the camera automatically selects the aperture to be as wide as possible (F2.8).
Depth Priority (Deep) For no crop and 35mm crop, the camera prioritizes F8 when selecting exposure values. For 50mm crop, F11 is prioritized. This allows for a deep depth of field, enabling pan-focus style shooting.
