Andy K said:Have you considered the Cokin P System?
David A. Goldfarb said:Heliopan filters come standard in thin rings, and B+W make wideangle filters with thin rings. The numbering system is different for B+W. A #15 filter should be about the same as a B+W 023 filter. Heliopan #15 is also called "Dark Yellow."
Andy K said:I have the A system, I wouldn't call them 'gel'. Many of the filters are made from mineral glass.
The P system is pretty much the same as the A System but is for larger diameter lenses and lenses with focal lengths below 35mm.
I actually prefer the A system to screw in filters as I can leave the adapters on my lenses and just switch the filter holder when I change lenses. I can also stack up to four filters without any vignette.
David A. Goldfarb said:If you check www.heliopan.de, you can find the densities (in German, but not too hard to figure out, even if you don't know German). I think a Tiffen 15 and a Heliopan 15 are about the same. If the goal is to match the filter on your lens to the filter on the meter, you might just get Heliopan filters for both. They are excellent filters though not cheap.
roteague said:You are right Andy. I have a Lee system myself - much better made than the Cokin system, but a lot more expensive. I also like that the Lee system is manufactured in the UK.
