This is my question,i would like to use a polarizer in my Contax.

I use a linear PL on my GSN/GTN and on my 50mm 1.8 Canon SLR lens with no problems. I was told a Linear would not focus on an AF camera but it works just fine.

"They" say that linear polarizers keep AF and AE from working on cameras, and that manual exposure usually is inaccurate; as I don't use Linear PLs, I know of nothing to in/validate these claims. Maybe the filter industry just wants to make more money selling the more expensive Circular Polarizers...

Well, seeing as the G1 and G2 don't AF through the lens, I don't see any problems with using a linear polarizer... this camera is a rangefinder, so only if the rangefinder parts are blocked will you not focus.

I can't comment on the linear versus circular and AF/AE. I have only used linear and that on an AE SLR over 30 years old. Worked fine. But how anybody could say manual exposure was usually inaccurate without qualification beats me.
Maybe "they" are talking about cameras that have an ability to give stepless shutter and/or aperture settings. My Fujica ST 901 is like that on shutter speeds. However, most hand held meters allow you to see pretty closely if you are between stops.
Even so, it doesn't define accurate. Use of a spot meter may give you more accuracy than an in-camera meter, even if it has a spot setting.

you can't use a linear polarizer on AF SLR's The G1/2 doesn't focus through the lens so you can put anything including the lens cap and it will focus fine.
The only problem with lenear polarizers is that its difficult to adjust the amout of polarization since you arn't looking throught the lens. You have to take the filter off and rotate until you get the desired results and install the filter and adjust to best match the alignment you had with the filter off the camera.

Wow. Seems like a simple qualification would make things a bit less sarcastic:
linear polarizers _may_ cause problems with autofocus _and/or_ autoexposure on some cameras that conduct those actions through the lens. Any cameras that do not do those actions through the lens are fine with a (usually less expensive) linear one.

linear PL can cause problems on some AF cameras but not all (not my 10D) as to metering I have no problems on any camera I have used linear PLs on.

So,it's good idea or not?

If you are trying to reduce surface reflections and increase saturation in your pictures, a linear polarizer will work on a Contax G2. Because you are not looking through the lens to see the effect of the setting, you will have to take the polarizer off the camera, rotate it until you see the effect you desire, note that setting, and then reinstall the polarizer on the camera lens.
Some brands of polarizers have marks on the rim to show how much polarizing effect you are getting --- pointing the 'maximum' mark toward the sun gives you maximum polarization.

Bottom-line answer: It doesn't matter which kind of polarizer you use on the Contax G2.OscarGarrido said:
Additionally, as some have noted, you won't see the polarizing effect through the G2's viewfinder so will need to use some other method of adjusting it for the desired effect.

But that's not the fault of the polarizer, whether linear or circular. It's the nature of the rangefinder system.

Robert White sells a nifty little polarizer that uses a polarized sight mounted in the flash shoe. They each have numbers on the outside of the ring. To use it you look through the sight in the flash shoe and rotate it until you get the effect you want, note the number then rotate the polarizer on the lense. I think it is made by Kenko.

Speaking of polarizers and the Contax system - the Zeiss people had an idea some time after 1932 to solve the problem of "guessing what the effect might be" with a system of two coupled polarizers, one in front of the viewfinder window and the second in front of the (50 mm only) lens, the Bernotar Polarizing Vorsatz. Funny thing if you come to think that in that respect they were more modern some 70 years ago.
