And the sky is more beautiful ... :-)

Basically absorbed a Z-pole filter certain light components with the effect that at the optimum orientation for example. annoying reflections on water or glass surfaces are eliminated, or, for example reflections on car paint. Also useful if you need to flash with metallic designs.
Because even when the sky is clear disturbing light components can be filtered out (again, the alignment is sometimes relevant), the Z-polarizing filter is very often underestimated as a helper for beautiful landscape photos.
(For a thorough explanation of the operation please google)

As a new "Always top" lens of my holiday NEX I recently Sony 1670Z, which has a 55mm filter thread.
For my vacation in mountains I have therefore ordered the Z-pole filter, because I particularly love landscapes such regions.

For high-quality lenses come for me only quality filter in question. Therefore, I have (there are other hochertige filter by B & W or Hoya) I opted for Carl Zeiss.

I have to say - just for the pictures of South Tyrol Alpe di Siusi with brilliant blue skies of the filter was worth. :-)
