Hi all,
After a long research on which filters to choose, I finally choose the B+W 010 MRC.
Those one are very expensive in Belgium, and so I've check a lot outside Europe and find this eBay seller Roxen, here
is the link where you can check those filters.
Do you find the price to be too low to be honest ? I mean can those filter be fakes ? They seems to be cheap compared to B&H... and others.
Can you please provide me your advices, ideas on the subject ?
Thanks in advance, and enjoy your weekend 
Laurent.
(but i don't know the prices to the UK). i use hvstar.net and i've been happy with them. the pictures look the same. one thing that makes a difference is that some of the B&W filters are brass while others are aluminium, the AL ones are cheaper.
