A sun visor just ...

A lot of it is really not to say. The sun visor fits (the Cokin filter holder BP-400B), as it should.
The filter change there is with mounted sun visor no problems at all ... R. Mattner review is very misleading (and almost stopped me from ordering the sun visor). The sun visor can clipping on at two positions on the BP-400B: In the rear position actually only the rearmost filter insert remains accessible. In the forward position, all three open. Everything else would not make sense (I have not even tried, the sun visor upside to mount - then you could forget all that is graduated filter ...)

Speaking: I do not use the Cokin filter, but the 85mm of Formatt Hitech. The fit perfectly into the BP-400B (although to my knowledge a 84mm Cokin P-system). If I am to believe the relevant review, it fits even better than the own plastic holder of Hitech ... 8- |
