Due to the particularity of Canon R series micro-single optical path, aperture design and light incident Angle, slight dark angle interference will occur when using interference filter for imaging.

There are two solutions to solve peripheral interference phenomenon:

1>Cut out the interference areas of pictures.

2>By post processing via RAW (attach video tutorials).

Warm prompt

●When using NK-FF /EOS-FF clip-in filters, the lifting of the reflector will affect the optical viewfinder window (OVF), so you have to use Live View mode for shooting.

●Due to the different lens optical design of different manufacturers, part use of fisheye lens, ultra wide Angle lens and wide Angle lens may lead to image fuzzy at around. It is normal. Or you can choose L-Pro UT, the ultra-thin model to solve this problem.

●Some entry-level models may fail to focus when using optical viewfinder (OVF) due to different focusing system designs. Using Live View(real-time display) mode for shooting will be recommended.

●Pls DO NOT shoot directly at a strong light source, because that may produce secondary reflection and lead to the degradation of image quality.

●When removing the clip-in filter, please place the camera flat and face up to avoid the filter touching the rear of the lens.
