I use a B&W polarising filter. There are many cheap and very expensive brands. B&W is in my opinion is good value for money.

I don't know what a digital polariser is but I'd buy a normal polariser if I were you. A polariser filters out polarised light and I don't see what 'digital' has to do with it. Polarised light is the same for digital and film.

Using Cokin P system, which is quite adaptable. Am currently trying out Canon's drop in polarizer filter with my 300 which a friend has generously lent me along with his 500 f4, while he's on holiday. :lol:

Filters & Hoods

Unread postby KampRunner » Sun Aug 27, 2006 10:53 pm

I want to buy a filter/s for my Canon 70-300mm lens as well as a lens hood. Any suggestions on which filters to get...can I get by with only 1 basic filter?. Can I use the same lens hood + filter on my 18-55mm lens?

Depending on what you will take photo's of, a filter that is always useable with most photo's is a cpl (Circular Polorizer filter) which gives a much deeper looking sky, takes glare away, brings out colours etc ...

And maybe a Nd (neutral density) filter, so that you can get slower shutter speeds in bright light for excellent pictures of waterfalls etc ...

The use of the same filter depends on the lens size, if both lense threats are 55 mm you will be able to use it on both, otherwise you will need a step up/down ring to make it fit.

There are lots of filters available doing lots of things, but I would say the first one to get is a CPL filter, You can also make other filters, a film negative can make an infra-red filter, a uv filter with vaseline on can make a soft focus filter etc ...

I bought quite a few filters although I use some of them rarely .

The 1 that I found most usefull , and it really can make for stunning shots is the polarising filter .
I would buy the type that screws onto the front of your lens.

You also get cokin filters which you can normally buy in a kit with graduated filters , that you can use to make for some interesting skylines etc .
They are square pieces of glass , that go in a holder in front of your lens , you can get different mountings to allow the same filters to be used on different lenses.
You can also get a cokin polarizer , but I found it awkward to use .

Lenshoods are designed for the lens, or rather for the view they give. Your 18-55 hood will look like only a strip of plastic as it can "see" a very wide angle, and would otherwise see the hood as well. Conversely, the one on your 70-300 will look more like a tube, as the 70mm is not very wide.
So, no, you can't use it on both lenses.

Filters... Why do you want them? What do you want to do?

First Filter should be a UV filter to protect the lens - one for each lens and kept on. Filters are a lot cheaper than replacement for a scratched front element. :shock:

The next Filter should be a CP - which you can switch between the lenses

Then get the Cokin P Series and ND 0.3 0.6 and 0.9

Always remember spend money on quality and not quantity :D

When you use a lens hood then you don't need a filter to protect the front lens element because the lens hood will protect the front of the lens. I never use filters for protecting my lenses but I alwas use lens hoods and I've never had a scratch on my lenses.

Have you guys checked out Singh-Ray filters the ND filters are TOPS and come in different f stp strengths. and they have the brilliant reverse nd filters with the main strength at the horizon to hold back the bright sun at sunrise and sunset and this brings out the details of the foreground. They fit in the normal Cokin P filter. Their screw in polorizers are the best you can get but unfortunately they are basically made on order and therefore very expensive up to us$ 400!!!! contact Bob Singh at www.singh-ray.com H'ell make you any filter you want a most helpful and knowledgable chap

Polarizer

Another question....

Ive been using polarizing filter, when using 18-55 lens, I get a beautiful blue sky, texture in the clouds etc, but when using a polarizing filter on my 100-400 lens you hardly see the difference in the sky or clouds, can any one tell me why this happens?

No lol.

I have a polariser for both my wide angle and medium (70-200) lenses and they work the same on both.

It should not make a difference as to what lens you use it with, its the filter it self that makes the changes so i have no idea why or how you are getting that to happen :hmz:

I'm no expert but both the long lens and the filter reduce the amount of light getting to the camera. Possibly the camera is struggling to adjust to this. You could try it with the aperture opened a stop or two and see what happens
