Circular polarizers
 

How many of you guys actually use one and do u really think its necessary for anything aside car photography? also what brand would u suggest?

Hoya and I love mine. I use it for car and outdoor photography mostly

I love mine, it really changes the look when you spin it. i just wish i had better lenses to use it on

I use a Hoya and just got a fairly large size so I use step up's so I can fit it onto multiple lenses. I love it.

I have one for all but one of my lenses. All of my filters are tiffen. B&W and Hoya are "higher" quality they say. But I don't have any experience with them, or proof that they are better. (besides the casing being made from other material) Obviously the $200 or so filters are probably better glass then the less expensive ones. but i haven't seen that much of a difference to justify the expense.

thats what im thinking, i tried more expensive UV filters and cheaper UV filters i have not seen a difference in color or anything(uv filters imo are just added protection from fingers and dirt) but i wasnt sure with a circular polarizer, i had one(cheaper best buy polarizer) b4 on my tamron 17-50 and i didnt like how any of the pictures came out very off WB and crappy colors :(but it obviously emits less light then for the sensor should compensate? or do i have to compensate on the canon from what the meter says?

I've never noticed any WB or color problems using a CP filter. The cameras metering should auto adjust for the amount of light coming thru the lens. All in all the CP filter should only richen colors and reduce glare.

Mine's a B&W, I made sure to get it big enough that it can be used on any lens I ever get, and it was worth the stupid amount of money it ran me because I do get constant use out of it :)

I use a B&W Multi coated Cpl filter and I love it. I use it mostly for auto photos, not when I do action photos like drifting or auto x since its to much work to keep adjusting it and its not that important to have a clear window on a car while its moving. Also I use it sometimes when I'm shooting around when any sky or water will be in the photo. It makes blues deeper and removes the glare in water so you can see though it more. Which you probably know.

I stand by C-PL filters, I made a non user of any filter get a cheap C-PL filter and he says that he'll always use it when he does automotive photos from now on.

i have the 77mm b+w one too. its great but hasnt seen much use since i like to use the hoods on my lenses and they make it hard to reach into them to rotate it

I use Hoya CP's on my glass.

Here is an example I have of a ****ty UV filter and what it can do...

See specs on hood

A poor UV filter will increase the amount of lens flare when compared to a better UV filter. Just google "UV filter test" and a few sites will come up with side by side tests.

As far as a CPL, I always have one on the lenses when I'm outdoors regardless of what I'm shooting. Protection, increased saturation, glare reduction.

Case and point with cheap UV filters causing lens flare issues, in this picture the tail light lens flare up at the top of the frame was caused %100 by the cheap **** Canon UV filter that was on the camera...

Not sure if i would use a UV filter at night but... that is quite the glare... :(

I have 3 Hoya Circular Polarizers

52mm (for my 50mm lens)
72mm (for my 28-135 lens)
77mm (for my 70-200 lens)

You can really tell the difference.

Why not just buy a step down or step up adapter and use just one filter?

I concur... I have a 72mm filter and then have a 52mm-72mm step up so I can use it on my 50mm and can use the 72mm on my 18-200. Also going to pick up an 80-200 lens soon which will then have its own filter.

I have one, but i cant use my hood and dont like having to swap them during a shoot. So i just invested another 100 bucks on another filter.

And 77mm filter on a 52mm lens... lol nah... (even though they do make them)

I have a 72mm filter on a 52mm lens, and its not that bad, looks a lil funky but its a nice money saver.

CP filters are great for cutting down glare when shooting cars. Especially glare on the glass. They are also great when taking pictures of water (lakes, waterfalls, etc). I use a 77mm Hoya as well.
