Have a 10-22 Canon and been thinking about a polariser.

Does anyone have shots with and without so I can what the benefit is

A poliarizing filter will reduce/remove glare from surfaces (window reflections/paintwork) etc and water. Normally, these have a rotating ring so you can all but eliminate glare.

I have one for each of my cameras and they are worth the investment. Go get one.

Be careful to get a circular polariser and not the cheaper linear ones too.

Linear ones don't work too well with digital.

Also if the front of your lens rotates when you zoom.... well, be careful of that too because it will affect the polarising once you've set it.

Polarisers can be quite thick too and on a 10-22 lens you will need to make sure you get a very thin one to avoid vignetting.

It would have to be a wide angle version

[Chunder]

Wide angle polarisers are expensive unfortunately, but they really add a dramatic element to pictures.
The detail in clouds jumps out, glare across water or metal disappears (it's still bright, but you can see details), etc.

The filter will reduce the light entering your lens, so you'll need a wider aperture and/or faster shutter.

It's also worth pointing out that any glass or plastic that's you photograph (and wet rocks sometimes) will exhibit a rainbow effect - perhaps not quite true to what the eye can see, but it can look pretty groovy

Here's a couple of "good" examples:

Here's some more of mine, and here are a whole bunch of other Flickrites ones...

[richard plumb]

can the wide angle ones prevent the effect you get with uneven polarisation, or are they just thinner to prevent vignetting?

I found with the Sigma 10-20 that at the wider ends you'd get uneven polarisation, so that parts of the sky would be darker blue, and others lighter blue.

Cheers for the feedback so far

But have you seen the price of a 77mm polariser

£57 for a Kenko one was the cheapest I have seen. TBH I never managed to get to grips with the ones I have so haven't bought one for the 10mm yet. Might do in time but before I sink £100 into a filter I want to know I can get the best from it

This shot here was taken with a Circular Polariser on my Canon 350D and you can certainly see the benefit with the bright colours and the deep blue sky.

I would definitely get one as they can really bring out clouds and help saturate colours.

See ya,

Mike.

That looks awesome!
