Hi fellow XPan users,

Anybody familiar using a 49 mm CP on the XPanII. I just bought one but I am still trying how to get the right angle. And I don't want to get the lens off all the time. (Allthough I think this is the only way).

Many thanks,

regards,
Jochgem
 
Hi Jochgem
I learnt this trick from a friend in Hong Kong. Screw the CP onto the lens. Take the light reading. When the meter is at the lowest reading, you have maximum polarizing effect. I have not tried it yet but it sure sounds effective.

By the way, I shall be getting my x-pan this week. I did not get the ND filter for my 45mm lens since I shoot negatives most of the time. Did you find that you had to use the ND filter? Would appreciate your experience on this.

Thanks
Daniel
 
Hello Daniel,

Nope I don't use ND filters. I am using my XPanII for about a year and I am only shooting slide film (RDPIII, RVP and RVP100F) with a centre filter. Adjusting and correcting with Photoshop CS and with scanning software.

BTW Your trick sounds very useful. I'll give it a try

Thanks very much!
Cheers

From all that I’ve read and from the B&H website…the Xpan lenses use a linear polarizer and not a circular one. All the lenses that B&H sells for the Xpan recommend a LP filter. Some of the others here (more experienced) may want to weigh in on this subject.


Cheers

While a Circular Polariser is unecessary, it is always okay to use one. When a circ. pol. is required, it is NOT okay to use a Linear one.
If you buy circular pols., you always have the right one regardless of camera design!

Based on suggestions gleaned from this forum, here's what I did: I purchased a Heliopan slim circular polarizer from B&H. Here's the working method. You hold the filter in front of your eye with the threads pointing towards you-same configuration as it will be when on the lens. You turn the filter until the scene has what you believe will be the desired polarization. I pay special attention to the corners, so as to avoid over-polarization (blue bleeding into black sky looks unearthly when magnified). Look at the polarizer and read the number you've chosen. Screw the polarizer onto the lens to the desired number. This works well, but I miss through-the-lens visualizing with the depth-of-field preview button of my H1.
Wish this filter were also available as a warming polarizer (Nikon's A2 would be great). One way this filter gets thin is by only having one set of threads-so you can't use it with a warming filter and the center filter because of vignetting problems. Hope this is helpful.

Hi Dick,
My Moose filter arrived today. It looks fine but without numbers (as the Heliopan has) what method have you devised to use it successfully?

Hi Dick,
Here's another problem with the Moose polarizing filter I encountered today. The hood for the xpan11 will not fit over the threads of the Moose filter as it will over the Heliopan polarizer. Too bad.

I use a Leica Universal polarizing filter,a adaptor ring E49 is needed for the 45mm and 90mm,centre filter of the 45mm do not need to remove when using this PL,the PL cost a little more than the centre filter.
the leica PL had been used on this photo,no edition is made to the photo,original colour.
