Er det dyreste verdt prisen?

26. What are the differences between the various B+W filter mounts?

F-Pro: Compared to the earlier standard mount introduced in 2001, the F-Pro mount has become thinner. Now it can be used with wide angle lenses, including most 24mm focal lengths on a full frame body, without vignetting. Another advantage of the F-Pro mount is it's modified retaining ring, which is no longer threaded in from the front, but holds the filter glass in place from the back. When removing a filter or lens hood that has been screwed on too tight to the filter, the retaining ring is not at risk of loosening. Diopters are mounted in the older mount due to glass thickness.

XS-Pro Digital: This mount is especially suited for DSLRs with wide angle lenses. This mount will avoid vignetting with most 17mm lenses on a full frame body. Some report success with lenses as wide as 16mm. It has a front thread for additional accessories such as lens caps or hoods. All XS-Pro Digital mounts are made of brass and are matte black to prevent reflections. Only UV, Clear, and Käsemann Circular Polarizers are offered in this mount, with the latest MRC nano coating.

 

Fra tabellen litt lenger ned ser det ut til at glasset er tynnere i det dyreste (4 mm vs 7 mm).

Det er forskjell på filtre, men det ser ut som andre faktorer enn prisen er avgjørende for kvaliteten...

 

Her er en test av variable ND-filtre som kan være til hjelp...ved valg av filtre på generell basis

Min tro om ikke dette er like bra som feet dyreste B+W?

De filtrene i første post. Noe av forskjellen er at det ene har dette. Fra samme side som JorunT linket til.

 

6. What is a Kaesemann polarizer?

Käsemann was an independent German company renowned for manufacturing some of the highest quality polarizer materialin the world. Schneider Krueznach purchased the company in 1989.

The quality and consistency of Käsemann material is uniform and neutral in color. In addition, the latest cementing technique used on these filters is guaranteed to prevent delamination. Moisture from humidity will destroy polarizing material if delamination occurs and this cementing technique protects the material by preventing delamination. Käsemann Polarizers are available in Linear and Circular. Note: The circular type comes with MRC (Multi-Resistant Coating) through 95mm.
