Well after the back order status, I got my Cokin P infrared filter sent and what I got inside the Cokin 'P' series case was a Cokin 'A' series IR gel inside a little holder that makes it into a 'P' series.... What a crock. I have to use the Cokin P wide angle adaptor as it is with my Hasselblad 500 CFi lens or I get vignetting. So with this adaptor, it's back to vignetting! I checkd by taking out the filter and just inserted the A to P spacer. At any rate, thought I would share my frustration and ask if anytone else has experienced this? I have an email into Adorama who seems to be the only outfit that has the Cokin filters available right now. It should be a 'P' series and appropriately sized Gel. What say the experts??
