Polarising Filter
Discussion
Just a quick one guys, i really need to get a polarising filter for my 450D, are these the same thing?

For digital you will need a circular Polarizing filter. (Not a linier )
My Hoya circular Polarizing filter feel apart after only using it a few times.
The only advice that I would give is that there is a goo chance that you will want to us it on your widest angle lens and the filters tend to be deep, which will give you cut of in the edges of the picture when you stop down.
I would therefore advise that you buy the biggest diameter filter that you can afford of good quality B&W then to be good. and use a step up ring. For my canon (Most lenses are 78mm if I am correct) I choose a 105mm circular Polarizing filter with a step up ring. It wasn't cheap. about £ 148 if I am correct. but it was worth it,
Hope that helps.

Years ago I bought a Hoya Multi-coated (Expensive range not their then budget range) linear PL lens for my 35mm stuff and it has lasted well and worked well. Must be nearly 30 years old now.
More recently I bought an own brand circular PL for digital from a highstreet retailer on a whim (which I think is Cokin) and the results seem less convincing. I suspect the new one has less good anti-flare properties and engineering quality.
I would agree with the 'buy oversize' philosophy up to a point. However the costs escalate dramatically as the size increases and a very large filter may not be terribly convenient in use or even to carry around. Totally useless if you end up leaving it out of the bag ...
PLus you are going to lose up to 2 stops almost as soon as you deploy it for even mild PL work. In 35mm days even the zooms would cope with that reasonably well but digital zooms tend to be slower to reduce glass costs and weight so your options for use across several lenses may be compromised somewhat depending on what you end up with.
Your links seem to be suggesting a 52mm fit. I would go for 58mm and step up rings for common lense size versatility but larger than that and you are heading into high price territory so only go there if you can be reasonably sure you will need to in the future. Even then you could always trade up later and sell the original to offset the cost.

Just a word of advice.
If you happen to be in Iceland at a place called Thingvellir where the two tectonic plates meet and you happen to put your camera on a tripod and attach your nice expensive polarizing filter to the front of your Lee filter adaptor, then you decide that you would be better the other side of the rocks and opt to lift the camera/tripod over your shoulder to move it ten feet. What will happen is that in the process of lifting it over your shoulder, the small clip that holds the circular filter in place will catch on your rucksack strap causing the filter to be released from it's holder and make it's way downwards with the aid of gravity to bounce off a rock that's been placed perfectly on the groun to provide a deep enough chip out of the filter which will cause you to recompose most of your shots for the remaining two weeks of your trip so that the chip couldn't be seen in any further shots.
Go on - ask me how I know.

Mike. are you shooting film or Dig?
It is correct that a linear is better than a cirular. But for digital it is recommended that you use a circular
I'm using digital. I like linear because I can determine which reflections I want to remove. I'm under the impression that a CP filter has no user involvement and just filters out all reflections? I don't know why CP filters are recommended over linear but I'd like to know.It is correct that a linear is better than a cirular. But for digital it is recommended that you use a circular
Ideally I'd like another linear filter so I can use them as a variable ND filter in very bright conditions.

You need to ditch your linear and buy a circular if you are using a DSLR.
The end effects of both types are the same. With both linear and circular types you still have to choose which orientation the filter is (by rotating it) to choose your desired effect.
Hope this helps.

i have got 52mm thread on all of my lenses, 18-55IS, 55-250IS and 50mm Prime.
I will have a look at going larger but as you may have guessed from the links above i am not going to spend a fortune.

I reckon you can get a decent used 52mm CP or linear filter of eBay for about £5. If I were you I'd go for one of those unless you plan to change lenses in the near future. Save money where you can to spend it where you want I will have a look at going larger but as you may have guessed from the links above i am not going to spend a fortune.

Are you sticking this polarizer on the kit lens you got with your 450D? Or have you got some other lens. I only ask because I think that the kit lens takes a 58mm filter not a 52mm. Worth double checking but either way you definately need a circular polarizer and NOT a linear one.

As for using polarizers with very wide angle lenses you have to be really careful because the angle of polarization varies continuously with the angle from the sun (it polarization is most strong when at 90 degrees to the sun, at 180 degrees the effect is virtually non existent). With using a polarizer with a lens much wider than about 28mm you can get unevenly polarized skies (much darker on one side than the other for example) and so it is often thought best not to use a polarizer for ultra wide angle lenses.The only advice that I would give is that there is a goo chance that you will want to us it on your widest angle lens and the filters tend to be deep, which will give you cut of in the edges of the picture when you stop down.

Triumph is also correct about the affects that using wide angle lenses might suffer from uneven polarization, This is not to say that you can not get good results.Snapper7 said:

Working in Layers and HD imaging will be a better option a lot of the time where possible. Although this is some thing that can't always be done.

But on Mikee Boys comment, "Ideally I'd like another linear filter so I can use them as a variable ND filter in very bright conditions".
You can't use two polarisers together because they will block light from both directions. I would suggest that you lower your iso and stop down more in the first instance . Failing that, if you need slow shutterspeed you will need to get some ND filters..

Thanks Pal, i was convinced they were 52, just check as i write this and you are right, kit lense and my 55-250IS are both 58mm.Yes i will be getting a circular.

Can somebody please explain why it has to be a circular one.Gassing Station | Photography & Video | Top of Page | What's New | My Stuff
