andybarton Posted October 20, 2007 Share #2 Posted October 20, 2007 It's difficult, but it can be done either with a third-party filter (by setting it off-camera and recording the relative positions of the two halves), or using one of the fancy Leica ones which hinge over the viewfinder and then swing back.

Michiel Fokkema Posted October 20, 2007 Share #4 Posted October 20, 2007 Hi, I use the Leica universal polariser. Works very well. On my Bronica rf i use a normal polariser. but i have two. On both of them I engraved numbers which correspond to their direction. Off course I made sure the numbers in both polarisers match the direction. In this way I use one polarisers to assess the position I read the number and set that on the polariser on the camera. This is like the Kenko system but can be considerable cheaper.

fotohuis Posted October 21, 2007 Share #5 Posted October 21, 2007 Most people have already a nice 77mm polarizer filter for their SLR. You can put it on an M with the Heliopan 77-55mm Leica-R.F. converter (filterview) and then bring it back with the Helopan reducer rings to the right size: e.g. 55-46mm and 46-39mm. Leicagoodies is offering the same solution. www.leicagoodies.com --> STEPS Link to post Share on other sites More sharing options...
StS Posted October 21, 2007 Share #6 Posted October 21, 2007 I guess rangefinders are not the best concept for polarizing filters... neither are TLRs by the way. Not that I have really missed it yet... Link to post Share on other sites More sharing options...
fotohuis Posted October 21, 2007 Share #7 Posted October 21, 2007 Advertisement (gone after registration) TLR cameras can be equipped with the Minollta auto pol system. Indeed a bit less confortable with RF cameras due to the critical position of a polarizer filter. But the Heliopan solution is very practical and relative cheap.

Adrian Strooper Posted October 21, 2007 Share #8 Posted October 21, 2007 Hi Rob, I would say, having a bit of experience of southern skies, I'd be really careful with a polarizer. You'll most likely end up with really REALLY dark blue almost black. I reckon a super duper U.V. filter would be better. 2 if you can! And you'll be ok. U.V. is really harsh there, but the air is incredibly clear and contrasty. When it isn't raining.... Having said that, if you want that incredible contrast in the skies go for it, also could be good to get the most out of the wet foliage! I reckon the heliopan adapter ring with a hole drilled where the viewfinder looks through would be a good option. P.S. even though I live in Berlin I'm Australian. And just came back from N.Z.

robsteve Posted October 21, 2007 Share #9 Posted October 21, 2007 Rob: In the old days, you just turned the polarizer until the logo or mark on the ring pointed towards the sun. Try this and you will be surpised that it still works. For B+W polarizers, you used the B+W on the ring as the reference. For example, if the sun is up and over your right shoulder spin the polarizer until the logo is at about a 45 degree angle off center and to the right when the camera is point in the shooting direction and you are looking at the lens from the viewfinder side.

ihw Posted October 22, 2007 Share #10 Posted October 22, 2007 You can use the TTL lightmeter on M6 etc to assess the maximum polarizing effect since there will be up to 2 stops difference between pola and non pola readings. This works fine on the M6 and CL providing you are happy with a maximum effect. If you need a more subtle polarizing effect you will need to revert to the visual measures already suggested in this thread. The tip about pointing the index mark to the sun's direction is interesting. I'll try it out next time we get some sun! Kind regards Ian Link to post Share on other sites More sharing options...
pauledell Posted October 22, 2007 Share #11 Posted October 22, 2007 For my B+W E39 polarizing filter, I used 1/4" labelmaker tape cut to fit completely around the outside of the ring and taped on. I embossed numbers 1 through 12 with a period between each number. For use, I look through the filter and revolve it until the desired effect was acheived. I note which number is located on top. I then installed the filter on the lens and set the number on the filter tape so it is located the same . It seems to work fairly well. Paul Link to post Share on other sites More sharing options...
