full time on CPL

you don't need polarizer filter on at all time, it only needed at some situations.
it cut down 2 to 2 third stops, make you using bigger aperture, slower shutter or higher ISO bcos losing some lights, may have difficulty in focusing as well.
having extra glass will always affect image quality, the only truely non-interfering medium is empty space. 2ndly, 1 or 2 stop could make a difference if you are trying to capture a moving subject or for night shoots.
Do you put suntan lotion on your whole body 24 hours a day 7 days a week all the time?
:think:
So pay a lot more money just to buy camera with better ISO performance, only to dumb it back down with a filter.
Very wise thing to do.
:bsmilie:
In addition to all the reasons already mentioned, you sure you want to use a dim viewfinder? Esp for night shots? Good way to miss something in your frame and an aid to bad composition.
I will be the devils advocate here and ask you to try it out for sometime yourself. You do get some benefits from reduced reflections for some surfaces, better contrast and colors, reduced hazing and of course bluer skies (In The Right Situations
).Of course you'd loose a stop or two and it does not work all the time (wrong angle; night time; no blue in the sky at all; etc);
No harm to experiment...
When the CPL is on:
1. Less light reach the sensor
2. You compensate by using wider Aperture, slower Shutter Speed or higher ISO
3. This will result in thin DOF, camera shake or grainy pictures
If you are lazy to remove filter, you're better off with a PNS camera.
When i first started shooting some yrs back, i also hooked my Nikon slim CPL on my D80. Happy snapping away in Budapest for a day, and the idea of loss in light dawned as the sun starts to set. :bsmilie: The CPl became a PRN usage from Day 2.
Sometimes u have to try to learn. I did not have the hindsight to post the query, but there is definitely some take home message from the contributions of the forumers.

I suggest you visit this thread again one year later, to review this statement of yours.
true, but since i use that only on my wide angle lens which i use almost exclusively for landscape, then it's ok. i'll be using a tripod and small aperture also.
maybe, but i don't use it for other lens, except the 16-35.
i certainly will.
Wide angle + CPL may actually work against you, since you can get uneven darkening of the sky. Sometimes it's ok, but other times can look odd. Just have to keep in mind if you have the CPL on a WA lens all the time.
CPL on UWA is not the best idea.
