FAQs

1. Does this adapter work with Canon EF-S lenses?

Yes, this adapter is fully compatible with both EF and EF-S mount lenses, allowing you to use your existing crop-sensor DSLR lenses on your EOS R series camera.

2. Can I remove the circular polariser filter?

The adapter is designed for A-type drop-in filters. You can easily remove the included CPL and swap it for other compatible A-type drop-in filters, such as a variable ND (sold separately).

3. Will autofocus and image stabilisation still work with my older EF lenses?

Absolutely. The mount adapter maintains full electronic communication between the lens and the camera body, ensuring fast autofocus and effective image stabilisation are preserved.

4. Why use a drop-in filter instead of a front-mounted one?

A drop-in filter sits behind the lens, meaning you only need one filter for every EF lens you own, regardless of the front filter thread size. It is also the perfect solution for lenses that physically cannot accept front filters.

5. How do I adjust the polarising effect?

The included drop-in CPL features an external adjustment dial. You simply rotate this small dial on the side of the adapter to dial in the exact amount of polarisation you need while looking through the viewfinder.

How to Use

Simply attach your EF or EF-S lens to the front of the adapter, then mount the adapter assembly directly to your EOS R camera body. Insert the drop-in circular polariser filter into the designated slot on the adapter. To adjust the polarising effect, look through your camera's electronic viewfinder and slowly turn the external dial on the drop-in filter until you achieve the desired reduction in reflections or boost in colour saturation.

The Canon Drop-In Filter Mount Adapter EF-EOS R with Circular Polariser Filter is an essential tool for photographers transitioning to the EOS R mirrorless system. By maintaining full compatibility with EF and EF-S lenses while integrating a versatile drop-in CPL, it offers creators a streamlined, cost-effective way to manage reflections and enhance contrast across their entire DSLR lens collection.
