Re: [OM] 18/3.5 & c-pol

[Henrik Dahl]

I haven't actually thought of an apperature difference (didn't know 
there was one- my ignorance). When I last recalled the vignetting 
problem I used ASA200 Fuji Press on a clear, sunny day. I would guess 
the 24/2,8 was stopped down to 8 or 11. I've had a hard time even 
finding a shop that offers slim-line filters here in Stockholm. "Oh, 
I've heard of that" is the usual answer. Guess I have to order a B+W 
one. But I would like to get that 85/2 first. And a backup OM-1. 
And... :-)
