Hi everybody!
I want to buy a Samyang 14mm f/2.8 to shoot landscapes, but...there is a big but:
is there any way to use a polarizer filter?
Without a polarizer I guess I can have lot of troubles in that kind of photography, so I'm trying to know if there is a solution.
Any help? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/unsure.gif' class='bbc_emoticon' alt='

I just bought one (14mm lens under Bower name but still the same lens), and put it through some pretty extreme variations in environment and lighting conditions on its first outing this weekend. I also use a 24 tilt shift and have the Cokin X-Pro filters for it including the polarizer (12 centimeters across), and even with this large filter you can see the edges of it when hand-holding in front of the 14, and you get a pretty bad reflection off the filter anyways because of the distance to the lens hood petals. To use the universal adapter you would have to cut the two larger petals down to the height of the front element, and even then you wouldn't have a secure fit because the plastic petals are quite flexible.
That being said, I had no problems with the lens in terms of colour saturation or unreasonable flair in harsh lighting conditions, and did use split neutral density filters since they easily covered the angle of view and I could block the stray light coming from behind them because they are square and larger than the polarizer, and because I was using it in flat lighting. The only real problem for me was the front element was fogging badly as I descended from the alpine back in to the forest. Granted there was a lot of rain too and I SOAKED the lens, however I still didn't have the same problem with the 24 it its smaller element.
I did have a few images with water in them up in the alpine, but I just used the reflections as part of the image rather than try and get rid of them like I might with a polarizer. I am attaching two links to photographs taken with this lens. One is from the 5D MarkII and is uncropped so you will see the whole image with some levels adjustment and sharpening and how it performs in harsh light with blue sky. The second image is cropped, and I was clowning around trying to make it look like it had a high dynamic range but I have a ways to go, however the width is the whole frame of the 14mm on a 40D using a two stop hard-step neutral density filter (17cm x 13cm) to darken the sky a little like you might get with a polarizer.
