【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.

This is a mount conversion adapter for attaching M42 mount lenses to Sony E-mount camera bodies. It features a new design (IV series) with K&F Concept's corporate color orange on the camera mount.
[MF & Infinity] When using this product, since there are no electronic contacts, focus is manual and aperture adjustments are all manual. Infinity is possible. Other functions will not function properly while using this adapter ring. (Please turn off the camera when attaching the adapter.)
[Unique Design] The 4th generation lens mount features a knurled finish and anti-slip treatment in key areas, making it easier to hold and operate. Meanwhile, the CNC-machined, finely engraved edges enhance the texture.
Durability: The aluminum alloy and brass construction ensures a high-quality finish that won't wear out your lens. The mount adapter mounts smoothly and securely on both the lens and camera. The bright black/orange color scheme adds a stylish touch to the mount adapter.
[Matte Paint] To prevent light reflection, the interior and exterior surfaces are painted with an effective matte finish. This creates a subdued finish and improves scratch resistance. The body has a beautiful design and finish, and does not detract from the quality of the camera or lens attached. / Manufacturer's Warranty: Please refer to the seller's "Focus Studio" page.
