نمونه مواردی که الزام به استفاده از فیلتر پلاریزه روی اولترا واید برای عکاسی طبیعت (منظره) هست (و ژانر مورد علاقه من هم هست!):
لنز 15م م زایس روی EOS 1D
با فیلتر پلاریزه
With-CPOL-Filter-2.jpg
بدون فیلتر پلاریزه
Without-CPOL-Filter.jpg
با فیلتر پلاریزه
With-CPOL-Filter.jpg
بدون فیلتر پلاریزه
Without-CPOL-Filter (1).jpg
نمونه های بیشتر و توضیحات را هم می توانید اینجا ببینید.
به نظرم حکم کلی فیلتر پلاریزه هیچ استفاده ای روی اولترا واید ندارد نادرست است.

The Ultra-Wide Angle Circular Polarizer Unevenness
As you can see in the above example, CPOL filters used at 15mm are going to show unevenness in skies. You will sometimes want to avoid this use, but I still often prefer partially-darkened skies for the effect. I will include examples in the sample pictures for this lens. Regardless of your taste for unevenly darkened skies, the difference these filters make in other uses, especially landscape photography, makes them indispensable. Here are two comparison examples:
Watch the CPOL filter bring out the rich colors in the moss, water and foliage by cutting the reflections on them.
I should clarify that all of the images in the above comparison were captured with the CPOL filter in place. The filter was adjusted to allow most of the reflections to show in the "Without" example - as would be the similar case if the filter were not installed. Otherwise, both images in each comparison were processed identically. The with-filter improvements appear much more significant in the full sized images.
