Mamiya 7II Polarizing filter (Mamiya ZE702): How do I use this thing?

[Markus]

Hello,

after my first rolls shot with the Mamiya 43mm lens I want to use a POL-Filter. Mamiya has a filter that can be rotated for meetering.
Can I use a normal Filter from B&W circular or linear by just adding a factor of 1 or 1,5 stops for exposing?

I believe the Mamiya polarizing filter is rather unique in the way it attaches and allows you to rotate it to the position for getting the full polarizing effect,something you can't see through the rangefinder viewer. Hope others will correct me if I'm way off base with this.

Yes, the Mamiya polarizing filter swings up so you can preview the effect. You could try to get it close by marking the spot on the filter edge after you stick the filter over the viewfinder. It's not ideal, but neither is using a polarizing filter on a wide angle lens; uneven polarization is probable. And you do need to manually correct exposure since the Mamiya doesn't meter TTL.

Ok, the Mamiya Pol-Filter would be the best solution. But no store offers it and the price is somehow unique too: 240$ or about 270€. The best Filter from B&W (Schneider Kreuznach) sells for about 100€ in 67mm diameter.
My solution would be a correction of the exposure times by 1 or 1,5 stops and mark the position on the filter, where the stronges effect appears. I have never payed attention to this with my DSLR, but I think the grade of polarization is always the same for each position of the filter.

Just to remind you of "Segetis' " remark concerning the polarizing effect with
wider angle lens .With a polarizer on my Bronica ETR 40mm the varying effect across the sky is hard to dismiss.

I know this effect and I agree with you. Sometimes I like this effect especially when there is a lot of blu sky in the picture. And I could use the filter on the 50mm too 😉

EDIT: The best (cheapest) solution for me would be an adaptorring.

Buy a warm polarizer filter or the most neutral you can find, either linear or circular. Don't over polarize you pictures!

They sell for about $100 on ebay used. No need to buy new ones.

I hope someone will respond as I'm thinking of getting one for mine and I have no idea as to how it functions either.Peter

The polarizer is not meant to cover the viewfinder window. You just look through it by peeking over the camera body, adjust the rotation and swing it back over the lens. It's a little bit clumsy, but it works fine.

yeah, don't bother trying to use the viewfinder to look through the polarizer. Just eyeball it to get correct polarization.

For metering, I usually dial in 1 2/3 to 2 stops compensation using the exposure compensation dial. (e.g. overexpose 1 2/3 to 2 stops when using the filter).
