I just bought,via mail order ( a necessity from here), a polarising filter for a 50mm summitar from a dealer in London. The filter arrived in a beautiful little Leitz leather purse and showed great promise on first sight. It has some signs of fungus growth around the very edge which I presume is in the middle of the sandwich of glass, but what is most bizarre is it doesn't appear to have any polarising effect! Now either I'm going blind or its simply lost its ability polarise - is this possible? At certain angles to the light faint parallel lines are just visible, so I'm fairly sure it is polarising glass and hasn't been swapped. I know the shop and they are very reputable. I will send it back and wait for another to appear, but would be grateful for any explanation of this anomoly. Nick Jackson Kuala Lumpur
