Terra - Give it up Dooragdragon never said iy was his info , provided some helpful info - that what forums are for - info
such nitpicking is uncalled for you provided nothing to the op except for your rant.
My guess is the op , based on his question would be appreciative of the extra info.
You can do either: auto focus or manual. Some pros use manual only, but it is really personal preference. As said above, you must be aware that the CPL, depending upon brand name, will cut the light entering the lens by 3 to 6 stops. Therefore, some OP's use a CPL as a neutral density filter in specific subject matter. The filter should turn with ease, so 1) focus first, then turn the filter to the desired about of effect from the polarizer if shooting in manual. Depending upon the make and model of lens, auto focus first, then adjust the polarizer for desired effect. Best to be at right angles to the sun for maximum effect. A CPL has little or no effect in gray cloudy days. If you have a LED camera back, take some practice shots to see what the filter is doing. If you do not have a LED back, bracket 3 shots: -1 one stop; 0; +1 stop. Select the one you want in post editing. A CPL can be a fun attachment particularly during the sunshine months. Here in Indiana, I rarely use it in the winter as we have lots of gray days, but it is always handy during the summer for landscapes and summer fun (water) times. Steve

Thank you for the kind response, it goes to show there is intelligent life forms here on the UHH.
I have this little square in the upper right hand corner of my monitor that says google, I use it frequently for things I don't fully understand or am seeking further clairafacation on.

Further to CPL: It has been my experience that Ops new to filters in general and CPL's specifically, do not take enough time with them to really see what they can and can not do. They buy one buy one because they have read or heard good things about them, go out and shoot one or two shots, look at the end result, and put them back in the bag where they stay for months. A fellow wiser than I told me a long time ago to mount the CPL on my "go to" lens, and go out and shoot at least 50 to 75 to 100 shots of all kinds of stuff, examine each day's activities, and don't take the filter off the lens until I could honestly say, "I understand how this filter works." I did take his advice and whenever I went outside I had a CPL mounted on a med zoom lens. I took about 50 shots within a two week period of all kinds of stuff in daylight: morning, midday and late afternoon in full sun. Boy, did I seen some very interesting things: the colors became more vivid, they sprang out at me on the monitor, b and w was more clear and sharp, the glare was gone from water shots, the sky a deep blue, etc. Since that time, I have a fairly good idea when and when not to use a CPL plus this newly found knowledge helps me plan my shots.

NO, NOT all of them...my Bigsig has a separate focus ring and the barrel DOES NOT rotate ditto for my Nikkor 40mm prime, my Sigma 150mm macro and my Nikkor 18 - 105mm...

The OP was querying the best way to use a filter with a lens that rotated the filter when focusing. Trying to make the OP look less intelligent than you helps no-one.
Who said pinky was intelligent?

Well, not entirely true - more expensive lenses do NOT rotate with focus - manual or auto.

Thanks, Dooragdragon. I have often read that one should use a CPL for DSLRs, but no one has ever explained how they are made or work (and I've never remembered to Google it). I appreciate your posting, even if some are rather petty in carping about it.

Focus first and adjust filter second. Then you'll need to re meter before shooting. Also, be careful with the wide end of your wide zoom lens. Because the field of view is so wide, the light enters the lens ad very different angles. This will cause the polarizer to have different effects ( or is it affects). You may see your sky vary in darkness across the photo.
Good luck.

The article does not address the OP's concerns anyhow.
Because then it will clearly show the words were not his

You are correct. I am becoming cynical about this site.
Your avatar, the kitty, is beyond cute.

Better lenses don't rotate the lens glass, so the polarizer remains where you set it.
Whoops! Already mentioned. :oops:
