Filters on an ultrawide angle lens??

[My2Girls66]

For those of you who have an ultrawide angle lens, if you put a filter on it can you see the filter at say 10mm? 12mm? I plan on hiking with mine and would like to get a CP and possibly a neutral density.

You didn't mention which lens you had. I think that for some UWAs you cannot really use a filter due to the curvature of the front lens element.

I have a Tokina 11-16 f2.8. I have never used a filter on it myself, and looking at the threads and how the front element moves on zooming, I would be reluctant to put one on, except maybe a slim-line one as there appears tp be not much room (if any) between the front element and where the filter would sit. Just looking at the thread, a standard thickness thread would likely end up with the front element being in contact with the filter at 16mm (though I have not tested it).

I have the Tokina 11-16 f/2.8 for Canon and have used a CP filter. There was some vignetting, but it fit fine. I was back and forth on using it for that reason, but in the end I love those brilliant blue skies too much and did opt to use it.

Oh yeah, its a Tamron 10-24mm for Nikon. Just picked it up today:) There looks to be just a tiny bit of room between the front element and the edge of the lens.

Depending on what filters you were thinking of using, try testing it out without first. A UV isn't really needed as the coatings are pretty good. A polarizer was one I use on other lenses a lot for the afformentioned deep blue skies, but I've found for some reason of all my lenses that the Tamron 10-24 needs it the least - it seems to almost naturally have a bit of a polarizer effect and delivers superb deep sky color by default. Now if you just wanted it for protection, that's another story. I've always used mine without a filter. I'd expect at 10mm, the tolerances are probably so tight that even slim filters may suffer vignetting. A larger filter diameter used with a step up ring might avoid vignetting issues, but that gets to be a pretty pricey affair when filters get that big.

Thank you for the responses. I think I will forego the filters for now. Even one for protection:scared1: I will just be sure to keep the lens cap on while its not in use. I was only able to get indoor shots with it today since its been pouring rain all day:( Its amazing how close I can get to my dog's and cat's faces(few inches) and it still focuses right in on them.

The polarizing effect of a CP will vary across the sky. The effect will be stronger 90 degrees from the sun. An ultrawide lens can show so much of the sky that a polarizing effect woudl be uneven.
