Thanks, it turned out ok but I did have trouble with the polarizer. On the RF it's hard to know whether you have circled to the polarizing part or are on the normal... at least for me. Maybe there is a trick to know what part of the filter is happening.
Yes very difficult to use a circular polariser with a rangefinder. What you can do is look through the polariser with your eye, get the orientation of the polariser right and then put it on the lens (this only works if it just clips on). You may have been better off with a yellow or orange filter instead.
