I use the Cokin P system with the standard and wide-angle holders, together with some Singh-Ray filters. I just found out about this Hitech wide angle filter holder for 85mm filters
, and am curious to know if anyone has any experiences with this product?
How does it compare to the Cokin P holders, especially the wide-angle version? If anyone has used Singh-Ray filters with both, do they fit as well as in the Cokin holders? Is it possible to use a SR sprocket polarizer and an ND grad simultaneously?
How does it fare with regards to vignetting with UWA lenses?
Can I use the Cokin P adapter rings with the holder, or do I need the Hitech ones?
Whew. Just want to make sure if it's worth purchasing before shelling out 100 bucks. Thanks.
