Hoya on Canon

[arunarchi]

Hi

Blue label Hoya crcular polarizer filter for a canon EOS ElanII e

and a 20-35 lens - 77 mm - the sky was washed out and I couldn't

find noticable difference when I look thru' the viewfinder and

rotate the polarizer - first, should I compensatee for the filter

with a different f stop? or second, is there only minimal change

with the combination of equipments I described above?

For a polarizer to have an effect on the image the sun must be approx 90 degrees to your side. It doesn't work for all angles of the sun. Play around with it outside on a sunny day - you'll see how it works just looking thru the viewfinder as you rotate the filter and point the camera around.

Hi Bill

 

I left out that part - I was shooting 90d to the sun - it was a sunny day and I still didn't seem to detect any changes as I turned the pol'zer - so, the question stands " first, should I compensate for the filter with a different f stop? or second, is there only minimal change with the combination of equipments I described above?"

No

Change should be quite dramatic, even just looking through viewfinder

Focus on some water, you'll see the changes then.

If, in fact, you were at a 90 degree angle to the sun, rotated the filter and didn't see a

dramatic change in the sky, something is terribly wrong. You either bought the wrong

filter (mislabled or defective) or have an eyesight problem. A different F-stop won't

make any diff.

Do circular polarisers have less effect than linear ones? I'm suspicious the linear one I had on my G3 was far more effective than the circular one I now use with my 20D...
