Heliopan 105mm CPL, any one used one?

[mreco99]

Hi
Looking for a CPL 105mm slim version (for lee holder)

Was going to get the Heliopan 105mm CPL, but hard to find much in the way of tests for CPL's
Only really this one back in 2009

And although it doesnt have the 105mm versions and its 2 years old, they dont rate heliopan much.
Cant really find B+w 105mm's here in the UK and they dont seem to be in the slim versions.

Any experience welcome.

Hi, I don't know the Heliopan pol filter but I got for the lee filter holder a Sigma EX circular PL filter in 105mm (it's not a slim version). I use it for about a year know and I am satisfied. The effect seems to be a bit less strong than my other pol filter. But it was the only effordable 105mm pol filter I could find. I paid last year 130€ for it at Amazon Germany.

I haven't tested it an UWW for vignetting, yet. Until 18mm on full format it should be OK with 2 filters slots in the lee holder.
