You will need to get a slim or ultra slim filter. B&H lets you select for only slim (one of the selections on the left side of the page).

Make sure you understand how you want to use the filter and read the reviews. Some are so thin that they will not accept a lens cap, and you will have to make other choices in how and when you want to use the filter.

Polarizers and wide angle lenses don't play well together.

The picture below was taken with a polarizer and a Tokina 11-16mm, set at 35mm equivalent of 24mm. I like the effect.

It's funny how vignetting is considered a fault in lenses, yet every editing program allows you to create vignettes for artistic effect.

Extreme example of "artistic" vignetting below.

Jerry,
Not meaning to nit pick, but can you explain how you set an 11-16 mm lens at 24 mm? Maybe I missed something. Nice snapshot though.

:shock: :lol:

He said it was "set at 35mm equivalent of 24mm" which means that on an APS-C sensor camera a 16mm has the same field of view as a 24mm lens on a 35mm camera.

As to the OP's original question, PrairieSeasons is correct in that you will need a slim polariser because the field of view on a 10mm lens is so wide it can 'see' the rim of a regular type filter.

yes i was i was informed after i bought the filter that it dosnt like wide angle lenses its a pity the salesman didnt tell me that as he screw onto the lens

If it was set to 16mm, multiply by 1.5 (crop factor), and you get 24mm. I got that figure from the meta data. It even mentioned "35mm equivalent."

I feel for you, John. Unfortunately, many of the salesclerks in camera departments know less very little about the products they sell.

Right you are. Best Buy is an excellent example. However, I recently went there to get a Wi-Fi extender, and the young slaesman knew what he was talking about and steered me to a less expensive Netgear that he said worked better. It has been working fine.
