Astronomik L-2 UV-IR Cut Filter for Canon EOS R

The clip-in design is highly versatile because it sits inside the camera body, meaning it works with any lens you attach to your Canon EOS R. You do not need to worry about filter thread sizes or step-up rings for your different lenses.

No, the filter is designed to be parfocal, which means it maintains the optical path integrity. It will not interfere with your camera's autofocus system or the in-body image stabilization (IBIS) of your Canon EOS R.

Yes, it is designed to serve as a permanent dust shield for your sensor. Because it is made of durable, scratch-resistant optical glass, it protects the sensor from dust and debris during lens changes without degrading image quality.

Digital camera sensors are sensitive to ultraviolet and infrared light, which can cause bloated stars, halos, and reduced contrast in long-exposure astrophotography. This filter blocks those wavelengths, ensuring that only the visible light reaches your sensor for sharper, cleaner images.

No, the Canon EOS R body only has space for one clip-in filter at a time. You will need to remove the L-2 filter if you intend to use a different clip-in filter, such as a light pollution or narrowband filter.

Installation is straightforward and requires no tools. You simply align the filter with the camera's lens mount cavity and press it into place until it clicks; removal is just as easy and can be done in seconds.
