This is probably a dumb question... but it's the first one that I've had.
I just got a new (to me) lens and the seller included a few filters with it... one of them is a Sunpak 82mm C-P.L.
I know what they are for, but how are they correctly used?
I've lookes for a manual or instructions on the Sunpak site, but found nothing.
Thanks!! |

| It gets rid of glare and reflections by only passing light waves that have a certain polarization. Best thing is to put it on and turn it to see the effect. |

2 ways to best see the effect is focus on the top of a green tree with the blue sky in the back drop, when you turn the filter you will see the difference in the Tree and the Sky, another way to test it is aim it at a car window outside. and turn it, at one point all you will see is glare and reflection when you turn it you should be able to see through the window removing the glare.

good luck using the filter they really do make a big difference. especially around unsettled waters.

I read what was in that link. But, now I have a question (hope you dont mind me hijacking your thread). It says you can see the effects of a circular polarizer thgough the LCD sceen, but not throgh the viewfinder of a Coolpix. Will I be able to see it through my viewfinder? If not, what can I do?

You can see it through the viewfinder. "Note that the effects of a polarizer cannot be viewed through the viewfinder of Coolpix 950/990/995"

The main thing to remember is that you have to turn it to see the effect more or less. If the front of your lens spins then it is tough to use too. That's why some lens description details lets you know if the front part spins or not. |

I dont think I'll have a problem with the 2 lenses I want to get...Sigma 10-20 and Tamron 28-75 |

I'm asuming the Coolpix has a window viewfinder that doesn't look through lens, like my camera. You will see the effect through an LCD or optical viewfinder as long as it looks through the taking lens, like with an SLR. |

Mike, the one addition I would make to the other very good comments is that you may want to use your DOF preview (probably a button on top of the camera). This allows you to see a much more accurate 'view' of what the camera 'sees' since it closes the aperature down to the setting that will be used when the pic is taken... this usually makes the view a bit dark. It is very useful tho.

I have a question too. Can a circular polarizer correct sky overexposure with clouds when shooting landscape with hills etc.. ?
And also can the polarizer allow forced slower shutterspeed in low daylight when shooting rivers?

I'm definitely not the best to answer this, but
Yes. It can correct sky overexposure, but it will also make the landscape darker as well.
Yes. It will also take the reflections, or a large portion of them, out of the shot as well. |

 karmat is right, a CP will kinda sorta work that way...
but what you really want is 1) a graduated ND filter to cut down just the sky and 2) a full ND filter (or several stacked) to get it really dark...
for 2, stacking a CP on top of a ND would work great, actually...

As a Coolpix user, I know this problem firsthand. For me, my viewfinder doesn't look through the lens, and in fact the view through the viewfinder is generally blocked by any lenses and filters I attach. To further complicate, what I see through the viewfinder is significantly cropped from what the camera actually records (like if I not to include the top of a tree, the top might end up in the file anyway since the viewfinder's view isn't as wide or as tall as the lens actually sees). But the LCD screen is fed through the lens.

He didn't ask the best way. Just if a CP would do it. :P
Actually, I've been known to stack everything in my bag if it was bright enough and I needed to get a bit slower. |

Thanks to the both of u. Think i've started in the right direction then with the C P. I'll have to follow up with the full set of N D filters 0.3,0.6,0.9 etc.
I ordered a 52mm - 58mm stepup and got a 58mm CP. |

It's not THAT hard, just gotta remember to keep your finger on the filter while the AutoFocus does its thing :-)

WTF! My 58mm CP filter is fused to the 52-58mm stepup ring. So now i can only use it with the 52mm lense.
I'm turning as hard as i can Counter-clockwise to get the CP filter off, but I can't get a real grip on it. I'm going in the right direction i should think??
It works good so far with my 52mm STOCKlense, getting better results now, but i want to try it on my 58mm70-300 |

The same thing happens to me sometimes, I have found that I was gripping the filter too tight when trying to unscrew it. I used a really light grip and it came off easily. I think if you grip the filter too tight it distorts slightly and binds up on the fine thread. If that fails, I think I remember seeing somewhere a filter wrench that wraps around your filter for easy removal.

| Using an elastic band (wide one) around the filter you want to turn will help with grip. |

To an extent, yes, but probably not in the way you imagine. The CP will increase the contrast between the clouds and the sky. If you want to darken just the sky, you will need a graduated neutral density filter. That or combine two different exposures into one final image.

Yes, but not really to the extent that you will get a lot of blur in the flowing water. A CP will increase your exposure by about 2/3 stop, maybe a bit more, maybe a bit less. What you want in this case is a plain neutral density filter.
