[Leica] B&W Filters on M8

[cummer at netvigator.com (Howard Cummer)]

Hi Len,
Your findings with the WATE and the B+W filter are very interesting.  
Sean Reid is doing tests over at his site and he suggests the  
Heliopan filters are a bit weaker than the B+W filters which are much  
closer to the Leica filters in terms of effects. Perhaps a 67mm  
filter from Heliopan will be more workable. If you get one and test  
it I would be very interested in hearing the result.
Cheers
Howard (in Hong Kong - who has been waiting for his lenses to come  
back from Solms for 9 weeks and for the Leica Filters even longer)
