View Full Version : Polarising filter

13th November 2008, 08:33 PM
I am looking at purchasing a polorising filter for my Bigma. There are several available and seek advice from others. Also, will I need to modify the lens hood or purchase a replacement bearing mind that I need to rotate the filter. Any help, general or specific to the Bigma, would be greatly appreciated.

In the past I've had good results with the hoya pro range

Don't be tempted to buys a cheap one you iften get strange colours - I had one from 7 day shop that sent the sky green rather than blue

Any of the usual high quality makes should do the trick, and on that lens you won't even need to worry abot getting one with a thin mount like you need on the 11-22

Do you use any other filters on your Bigma??I looked at a UV for mine ,the best price I found for a decent one was about 80.00.86mm filters don't come cheap.:(
Ended up not getting one.
I dread to think how much a good polariser will be.

Ps I seem to remember Hoya Pro filters don't go up to 86mm(may be wrong).

Thanks to Chris, Andym and Andy for your replies. Followed the link posted by Chris and found posibilities for Linear and Circular polarising filters. Checked out the differences and found 2 interesting facts that I would share with you.
1. Fitting the filter reduces the light by about 1 stop.
2. Never buy a Linear Polarising filter for an AF system.

Chris, The option for Hoya is within their standard range. They only go up to 82mm in the Pro Range. Thanks for the link it made me look more closely and I have learnt a little more.

Andym, I do use a UV filter and the price on the link page is 55.95. I use this filter more to protect the expensive glass and think its a good insurance policy.
