【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.
[Full manual telephoto lens]: 420-800mm telephoto lens, no adapter ring required, 2 seconds fast lens installation. After attaching the lens, you need to perform full manual focus operation on the digital SLR camera: 1. Adjust to M mode and use. 2. Twist the focus ring on the lens to focus, then adjust the ISO and shutter speed. (The lens aperture is not adjustable and changes depending on the focal length).

[Be careful with image stabilization]: This 420-800mm telephoto lens is a manual lens without electronic contacts, and does not have autofocus or image stabilization functions, so slight camera shake may dramatically affect the image quality. We recommend time-lapse photography, using a tripod or shutter cable to stabilize the image and take beautiful photos. Manual focus telephoto zoom lens is recommended for professional photographers, suitable for digital SLR cameras, not suitable for mirrorless cameras;
[Tips for solving overbright/darkness]: First, meter 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;
[Warm Tips]: 1) The lens does not support Canon EOS R, Ra, RP, R1, R3, R5, R5 mark II, R5 C, R6, R6 mark II, R7, R8, R10, R50, R100 | EOS M, M3, M5, M6, M6 mark II, M10, M50, M100, M200. 2) Not suitable for sports photography. 3) Avoid using the product for long periods of time in windy sand or large amounts of dust. Prolonged contact with humid air may cause mold to form on the lens, affecting its use. If the ambient humidity is high, we recommend using a drying box.
