Polarizing Filter

[jann1033]

i had to look but both of my cps are tiffen so guess they are not coated but i haven't had a problem with flare when using them one is pretty old though so maybe they have changed or something....i'd get the best you can afford( which can get up there quickly when it is a big lens diameter) and stay away from the really cheap ones on ebay etc. i am thinking my 72 mm was about $80 ( if memory serves). personally i think the tiffen has held up fine since i've dropped it afew times and it is still find....i'm sure the image might be degraded some but not enough for me to notice truthfully

Thanks for your responses. It doesn't make sense to put a cheap filter on an expensive lens, so I will go with a multicoated filter. Hopefully I'll find one tomorrow!

The best deal I found was a Hoya via an eBay seller... don't remember his name but I'm sure it'll come up if you search for Hoya filters. There's an online store, too, with mainly Hoya filters and a couple other small related items. Best price I found, plus quick and cheap shipping.

 

[BeautyLLM]

Thanks for the tip! I took a look but didn't see the multi-coated polarizer (well, there was one but it was shipping from Hong Kong). I'll just keep watching for it!

I am looking for a good polarizer filter for my 30D. Any recommendations? Brand? Model? What to look for?

Also looking for a good ND filter. Same questions.

I've had very good luck with a Hoya Super Quality circular polarizing filter. I don't know the exact part number or name but on the side of it, it says "Hoya HMC Super PL-CIR Made in Japan". The box says it has 7 layers of multicoating.

i really like my cokin nd filter,you can get all kinds of filters , i think even polarizers( not sure if they are circular or not but the filter holder rotates so i would guess they are) you get the adapter for the biggest lens you have then i use step up rings to go from that to smaller diameter lenses

for a cp i have a tiffen from a while ago, probably not the best quality but works ok for me...i bought the biggest sized lens mm i had at the time and use step up filters for the other sizes, except for a small size cp ( tiffen also) that i have )

I recommend Hoya multi-coated filters. I've also heard that B+W makes high quality filters. Tiffen are much cheaper and much lower quality.

For ulta wide angle lenses, such as Canon 10-22, consider using "thin" filters to avoid vignetting. Be aware that with ultra wide lenses that it is possible to over-polarize the sky, resulting in unnatural change in sky color across the field of view.

Match the filter quality to the lens quality. A $40.00 is probably OK for use on a 18-55 kit lens. For my 10-22, I choose the Hoya Pro1 Digital at $175.00.

Use only Circular Polarizing filters. The older Linear Polarizing filter will confuse the autofocus in most modern cameras.

You will loose about 2 stops when using a polarizing filter, so this sorta doubles as a ND filter. Be sure to remove the polarizing filter when going indoors.

I just added a CP to my collection. Is there a standard exposure compensation for these or do I just figure it out?

 

[mabas9395]

A CP should reduce the amount of light hitting the sensor by at least a stop. But the meter should recognize that and set your exposure accordingly. You shouldn't have to use any EC with a CP.

But since I don't own a CP yet, I'm not exactly the best person to answer your question.

That is correct. The meter reads the amount of light coming in through the lens. So when the CP dims the scene, it dims it for both the sensor and the meter. You don't need to do anything extra for the exposure setting.

 

[pjacobi]

Each scene will require the adjustment of the polarizing filter to achieve the desired amount of polarization.

The change in polarization will affect the exposure. Be sure to re-meter the scene after adjusting the polarizer, i.e. do not lock in the exposure setting, then re-adjust the polarizer.

Remember to remove the polarizing filter when shooting indoors. A polarizing filter is really inconvenient when constantly switching back and forth between indoor and outdoors.

hey guys,
i'm looking for a circular polarizing filter to fit on a canon powershot S3 IS. is there one out there? I'm not sure how to find out what fits what camera. or if any powershot owner has other filters to reoccomend, i'd love to hear it! just looking to get a little more into the technical side of photography and wondering what filters I should buy to start with.
TIA!

I think you will have to add a lens tube before you can add a polarizer since the moving portion of the lens does not have threads. Well, at least my DW's S2 does not.

But adding a lens tube, like one from lensmate, allows you to have then lens cap on while the camera is on.

I second the suggestion of the lensmate adapter tube. I've got one for my S3 and I (almost) never take it off.

They come in two sizes 52mm and 58mm ... if you are planning to buy only filters or Raynox lenses (DCR-1540PRO/DCR-250 macro, etc) you can get the 52mm and save a little money on filters.

If you want to use Canon TC/WA, or other popular ones like Sony, you need the 58mm adapter.

AFAIK, the phrase "you get what you pay for" applies quite well to filters and lenses ... the cheap ones (eBay specials) are rarely worth what you pay for them but Raynox, Hoya and B+W are very high quality and worth the price....

 

[quidam373]

thanks guys! good place to start.

 

[DisOrBust]

Back before kids, thats even back before digital, I always used a pol. filter to get the nice crisp shots. Can you do this on a digital camera??

 

[rhiansmom]

The circular polarizers are made for digital use

 

[bostran1]

I use one on my Canon Rebel XT all the time. If used one on your lenses on an slr, you can certainly find them for any lens that you use on a dslr (well, maybe not every lens, I just assumed most)

 

[jann1033]

i use the same cp i used with my film slr on my dslr
