enormous creative potential (... post was yesterday!)

This filter set is almost awesome, especially for the price.
The adapter rings are made of metal and very good. The filter holder and sun visors see the models over similar and also feel like that. The filter platelets fit perfectly into the guide rails and the filter holder in turn perfectly on the adapter. Attention is objetivnahe somewhat flatter bay for a round polarizing filter, which exactly matches the brim around the ring in the groove and thus maintains sufficiently stable. The tabs on the filter holder to prevent falling out of the polarizing filter. The tablets come only in the outer three bays, vo they remained stable but not too tightly by spring structures. The sun visors are very massive and accordingly stubborn up and set down, keep it but also very good. They are to be fastened in many ways. With their help and the second filter holder can be a second objective "wrong" grow what an interesting (albeit vignettiertes) Extreme Mega-Tele or a microscope can result. (Ok, bauble ...)
The filter panels are of excellent quality and processing. Too bad that neither a caption nor an indication of the filter characteristic is present. There's only experimenting and nachdokumentieren.
The many bemäkelte magenta cast the gray filter can only be seen on digital cameras and infrared-sensitive film. Here helps a Hotmirror (or a UV / IR cut filter, "Digital Filter") between the filter holder and lens. Only the darker (ND2?) Graduated filter still retains something then magenta. But that can also be used quite creatively. Or you can dispose of me the green curve in the second slot the Magenta final. Or you can "build" of different filters farbjustierbaren a graduated filter. The combinations are endless. The full-color filters are useful in some cases very strong and often more for contrast control in B / W photos or for Duka. The Graduated Filter tool could perhaps be a little longer to allow more Einstellspielraum. However, in principle, customary for the lens sizes range from easy.
The picture quality of the filters is very good. I have not experienced any blurring or distortion. Occasional flares are also easy to control.
The filter bags are certainly good if you do not often raus and purely doing the filter panels, since the optical surfaces to slide over the feed and the Platikflächen. Dust and sand would be fatal here. The filter cans eg Cokin mitliefert, are as much practical.
All in all a super filter set that is completely over and certainly worth a try for the price.
Anyway, I can save annoying computer sessions with color corrections, Nachberabeitung, etc ... deductions and Dias (analog) are simply colored, beautiful, real, dynamic. The expense is again shifted as in "old school" at the shooting place, away from the computer. For HD video Fimerei arise unprecedented new opportunities to achieve really nice shots with unexpected moods and dynamics (CSI :).
