Adapter for EF lenses - usage of polarisation filter form Ef prime

[daniela]

Hi Guys!
Another question, please:
Is it possible to use the polarisation filter of the 600mm L II lens with the EF to RF adapter?
(Canon Objektivadapter EF-EOS R mit Drop-In Filter V-ND (3443C005))

I would like to get this adapter and use it with my polarisation drop in-filter of my 600mm lens too, if this is possible.


Thank you!
Daniela

Nothing in the documentation mentions that, and Canon calls the sizes differently as well

If you mean that you want to use EF-RF-var-ND adapter and then add the EF 600mm's native polarizer in front of it just as you do with a regular EF mount camera, then nothing says that it cannot be done.
But will it be effective? Definitely No. Because it will look like as if you have both polarizer and ND filters in front of the lens. The regular ND filters do not polarize the light, but var-NDs do because they are composed of two layer of polarizers and when you put another polarizer layer in front, very strange things happen. Some parts of image will be bright and some parts will be black (according to Bell's theorem). So no, even if you can put them together they cannot be used together.

ok, not the answer I expected, as the filter looks similar to my drop in polarizer.
Hmmm. Maybe I´ll try get an adapter on amazon and try it. if it does not work, I will send it back
