12mm Heliar and Polarizer

[whitecat]

Will I be able to see the effect through the regular viewfinder before I compose through the 12mm viewfinder and shoot? Will the meter take care of the exposure?
Thanks

I should mention my camera is my Zeiss 35.

Leica used to make a flip out polarizer for viewing and adjusting the effect before you flipped it back over the lens. The polarizer does not cover the viewfinder. The meter, internally, should compensate for the polarizer. If not, make some tests and adjust accordingly.

The filter adaptor for the 12mm has a cut-out section at the top. If you look through that you'll see the polarization effect well enough. Your camera's meter, being TTL, will naturally compensate for the ND effect of the polarizer.

what mr phil said

and you get some funky effects, it has to be said

Thanks for the good info.

BTW if you look through the filter and turn it to the point of maximum effect and then put a mark on the bezel in line with the sun before you fit it to the camera, you can use that mark to set the filter simply by rotating it so the mark lines up with the sun again wherever you point it.

If that makes sense, easer to do than explain 😱

With a 120 degree angle of view you will get very uneven polarizing effects. The maximum effect only happens at 90 degrees from the sun.

If this is what you want for aesthetic reasons than have at it. I doubt you will really be able to judge properly through the viewfinder.

Also remember that putting a big chunk of flat glass in front of the lens will leave you open to lots of flare.

The nice thing about the 12mm is that it sort of forces you into viewing things differently. It's not just a wider wide angle.

Here's my little essay on this:

I get uneven polarizing in the sky without the filter, I think that’s just how the sky is
