Quick question as i've always used circular. Which type of polarizer is correct for M cameras? can you use both with same result? circular or linear?
thx
 
Why anyone spends the extra money for a circular polarizer for a manual focus camera is beyond me! A plain old garden variety linear polarizer will work just as well.

The BIG problem, however, is predicting the results you'll get with either of the types. This is one of the few advantages an SLR camera has over a rangefinder...you can see the polarizing effect immediately as you compose.

It's sort of hit-or-miss, but one method I've used (with limited success) is to watch the in-camera meter as I turn the filter. I've had moderately good results by assuming the lowest light level (shown on the meter) is maximum polarization.

If you can think of a better way, please post it.

Linear would do just fine.

I look through just the filter, note the orientation at the point where I get the effect I want and then put it on the lens with the same orientation. It's what I do with my 4x5 too.

I measured the outside cicumference of my E39 B+W linear filter then cut off numbered labelmaker tape (narrow) to the correct length and fixed it on the filter.
I look through the filter turning it to acheive the desired effect, noting which number is at the top, placing it on the lens and locating the number on the top as
I compose and meter to photograph. Using 1/4 inch tape, i was able to emboss 1 through 12 on the tape with a period between each number. It seems to work well enough.

There is NO DIFFERENCE between the two as far as the final picture.

Circ polas are for slr with meters and auto focus sensors behind glass that is already polarised. With linears, there is a position where the angles of polorization can cross at 90 deg and let no light to those functions.

The M camera has no such complications. Just be aware some older flip out polas for M were made without reguard for color film and they produced a green cast. Any made since 1985 will be neutral grey as will B+W.l
 
thanks for the replies. Because of time, i'm leaving in the morning, my solution will have to be a bit gash! I have a circular 49mm so im going to take that and when I want to use will just first look through the filter, turn for the result i'm hoping for and then hold against the front of the lens. Should work fine but on each shot I do I will take one without as well.
