Battery disposal
Information on the disposal of old batteries
The following notice is intended for those who use batteries or products with built-in batteries and no longer resell them in the form in which they were delivered (end users):
1. Free return of used batteries
Batteries must not be disposed of with household waste. You are legally obliged to return used batteries to ensure proper disposal. You can dispose of them at a municipal collection point or at a local retailer. As a battery distributor, we are also obligated to take back used batteries. However, our obligation to take back is limited to used batteries of the type that we carry or have carried as new batteries in our product range. You can therefore either return used batteries of the aforementioned type to us with sufficient postage or hand them in free of charge at our shipping warehouse at the address listed in the imprint.
2. Meaning of the battery symbols
Batteries are marked with the symbol of a crossed-out wheeled bin (see below). This symbol indicates that batteries must not be disposed of with household waste. For batteries containing more than 0.0005 percent mercury by mass, more than 0.002 percent cadmium by mass, or more than 0.004 percent lead by mass, the chemical name of the pollutant used is located below the wheeled bin symbol – where "Cd" stands for cadmium, "Pb" for lead, and "Hg" for mercury.

Description
K&F Concept EF-EOS R Lens Adapter EF-S (Canon EF to EOS R)
Condition and Limitations
Condition: used.
The product shows normal signs of wear and tear due to age, which are unavoidable.
This may include small scratches, slight discoloration, or minor material wear.
Slight age-related signs of wear, such as scratches or dull patches, may be present.
Using EF Lenses in the EOS R System
This adapter connects Canon EF/EF-S lenses to the RF mount of a compatible EOS R camera. The orientation is important: the lens side is EF or EF-S, while the camera side is RF. This allows you to continue using existing EF system lenses rather than treating them as equivalent to RF lenses.
Electronic Functions of the Specified Design
K&F describes the EF–EOS R model as an electronic adapter with autofocus, camera-side aperture control, and EXIF data transmission. It also supports the lens's built-in image stabilization. This is a different function from that of a purely mechanical adapter ring.
This Keeps the System Classification Clear
For shooting, select the intended focus and exposure modes on the appropriate camera. The adapter is not a separate focusing motor for a third-party manual system, but rather establishes the specified electrical connection between the EF lens and RF camera body. A Canon FD lens does not belong on this lens side.
Consider EF-S and the Image Format
EF-S refers to lenses designed for a smaller image format than full-frame. A suitable mechanical and electrical connection does not enlarge their image circle. For a full-frame EOS R camera, therefore, in addition to the adapter function, the crop factor associated with the EF-S lens must be taken into account.
