【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
[420-800mm Manual Lens] The 420-800mm zoom lens is a fully manual lens with no electronic contacts or autofocus function, so complete manual operation is required before shooting. The steps are as follows: 1) Attach the 420-800mm RF lens to the camera. 2) Search for "Release without lens" in the menu and set it to "Yes". 3) You need to do manual focus and adjust ISO and shutter speed. (Aperture can be adjusted using only the lens)
[Lens focal length/focus ring adjustment] 1) Release LOCK-OPEN/ZOOM LOCK using the manual on the lens. 2) Adjust to desired focal length (420-800mm adjustable). After adjustment, lock the focal length. 3) On the front of the lens, slowly turn the focus ring until the subject you want to focus on looks clear and sharp. 4) Adjust the ISO sensitivity and shutter speed depending on the shooting.

[Be careful with image stabilization] This 420-800mm telephoto zoom lens is a manual lens without electronic contacts, and does not have autofocus or image stabilization functions, so slight camera shake may have a dramatic effect on image quality. We recommend time-lapse photography, using a tripod or shutter cable to stabilize the image and take beautiful photos. If you have any questions, please feel free to contact us.
[Tips for solving overbright/darkness] First, measure and focus with a long focus, then lock the exposure. Then change the focal length and take the photo. This method allows you to change the focal length and still ensure proper exposure based on the metering point you originally set. If your photo is too dark, you can improve it by: 1) changing the shutter speed from 1/500s to 1/100s or even slower (e.g. 1/50s); 2) changing the ISO sensitivity from ISO 100 to ISO 200, 400, or 800 (e.g. ISO 200, 400, 800); 3) Change the position so that more outside light enters the camera's image sensor through the lens;
