The Meike Drop in Filter Mount Adapter enables the use of Canon EF and EF-S lenses on cameras with the EOSR bayonet. This adapter acts as an intermediate bayonet ring and supports autofocus, which ensures seamless integration of the lenses into the camera system. The adapter is equipped with a variable ND filter, which makes it possible to flexibly control the amount of light hitting the sensor. This is particularly useful for creative photography and videography as it improves control over exposure and depth of field. The scope of delivery includes caps to protect the adapter when it is not in use. The transparent filter ensures that image quality is not compromised. The Meike Drop in Filter Mount Adapter is a practical solution for photographers who want to continue using their existing Canon lenses while taking advantage of the EOSR camera.
