Polarizing Filter - What is the best method for RF Cameras?

[Michael Ta]

I wonder which methods are the most common for using effectively polarizing filters on RF cameras. Any experience with FilterView of PhotoEquip?

I use my lightmeter in the camera. Leica M6.

I get good results using a Kenko polariser and auxiliary viewfinder.

How?
I have a M6 TTL and an older Leitz polarizing filter and have always found it awkward to have to observe the subject through the filter first, rotating it in my hand, mark the orientation, screw it onto the lens, set the orientation of the filter, and then finally take the shot.
Do you perhaps turn the filter untill you get the lowest light reading? Does that produce good results?

Use a polariser with plenty of edge markings . Hold it to the eye and note the point at which the effect you want is achieved. Put polariser on lens and recreate that point. Expose by using manufacturer data on filter factor to adjust metered exposure- in my case two stops for most polarisers, 1.5 for my most recent B+W. I prefer to use filter factors than to meter through a polariser anyway since that risks compensating for some of the effect I'm using the filter to create, so the only difference between a rangefinder and slr for me is that with a slr I twiddle the polariser after I put it on the lens, and with a RF I twiddle it before.

Not too long ago from what I remember when reading one of the photo magazines there was a set sold of two filters both with edge markings. One for the hand and one on the camera. Of course it can be done when buying two of the same brand and marked as long as the markings concur.

I don`t use a polarizer when using a rangefinder, problem solved

I used 1/4" Dymo embossing tape typing numbers seperated by periods ( 1 thru 12) and applied it around the outside edge of the filter. By turning the
filter until the desired effect is acquired and observing the reference number
then placing the filter to the lens so the reference is located in the same
location. It seems to work fairly well for me.

That would be the Kenko set mentioned by Andy K. The viewing filter fits in a hot shoe or is hand held.

Leica makes/used to make a polarizing filter with a swing arm. You swing it up in front of the viewfinder, set it for the desired effect, then swing it back 180 degrees in front of the lens where the effect is identical. Don't know the current price/availability.

Comments by others in the thread about methods for getting the orientation on camera to the same as when viewing are on the mark.

I'd be surprised if two random polarizers by the same mfgr are aligned to ring markings. Of course you could make your own markings on two filters and go from there, or maybe loosen the retaining ring(s) and rotate the filter glass in the mount(s) so that markings match.

Mamiya has a unique Polarizer for their 7 II medium format rangefinders. It's on two swing arms which allow you to swing the filter up for correct viewing to adjust the filter, and to take the exposure reading, since the camera does not do ttl metering. Then once the filter is set and exposure calculated, the filter swings down over the lens for shooting.

That said, I do use Polarizers on my Leicas. Simpler to shoot B&W. Grin.
