Filters......

[stevegreen]

I have decided that I need to get some filters to fit my 350D.

I have been looking at both Cokin and Hoya filters but don't really know which to go for.

I will be initially looking at a Circular Polarizer and maybe some graduated filters.

The Cokin range looks good and I assume that I would be looking at the P series for my lenses (77mm threads on both the 10-20 Sigma and the 24-105 Canon) One thing that concerns me slightly at the moment is vingetting at 10mm. Will the Cokin range suffer from this? I'm assuming that a screw in filter wouldn't.......but they are soooooooo expensive!

Any advice/alternative suggestions appreciated.

I recently got a 77mm Hoya Circular Polariser as it fits all my L lenses. It produces some very nice effects. The only problem I have with it is that it is difficult to adjust with a lens hood mounted.

I'm also looking at graduated filters.

You can still get vignetting from a screw in filter. I have a 77mm circular polariser which covers all my lenses. I have been looking at the Cokin P series as I would like to get a graduated filter.

The only complaints I have heard about the Cokin system is light leaking in as the filter isn't a tight fit in the holder.

I believe Cokin do a 'Wideangle' holder for the P system. I think it is lower profile to avoid vignetting on wide angle lenses.

How right you are! This is the first sunny day here for a while so I've been out with an assortment of lenses and the circular polarising filter. Vignetting is most noticable on the 24-105 L at 24mm (This is on a 5D body)

You would need a wide holder for the 10-22, the normal one cuts in around 16mm.

I would recommend the Cokin system, definatelly a good buy. I found Hilton Photographic to be the best buy, on eBay. Let me know if you need their eBay id

Thanks for the replies.

I have just been into the local Jessops and the helpful chap behind the counter said that their own 'Pro' brand of circular polarisers are on 1/2 price offer at the moment and that they are as good quality as the Hoya brand (in fact he said they were the same apart from the branding) I asked him about vignetting at 10mm (16mm equivalent) and he said that the profile of the surrounds was quite shallow so I shouldn't see much vignetting at 10mm (16mm) Kaoshans post would suggest otherwise.

£53 for a 77mm thread circular polariser, Jessops brand, seems quite tempting but I wonder if the quality is the same or whether there would actually be that much in it if there were a difference. I had a look at the quality of a Jessops UV filter and it seemed to be quite good.

That's interesting to know - I'm going to pop in to our Jessop's at lunchtime to have a look...

You only really see bad vignetting if your aperture is open wide (i.e. low aperture value) - I've got a 5D, and a Hoya UV filter on my 16-35, and don't get too bad vignetting. It's mostly noticeable if you've got a constant colour scene - e.g. sky, snow, painted wall, etc.

Got a few of their filters and they are good quality

The Cokin cost me £9 for the holder [same again for the wide one] and £6 for the ring adaptors then about £12 a filter Very flexible and I'd say moreso than a standard screw on filter.

Steve,

With the 24-105 L + cpf on either a 350D or a 30D there is no vignetting at 24mm. It only occurs on a FF body.

But there would be on the 10-22mm bud

Even though the 10-22 is an ef-s lens, so the sensor doesn't actually gather any (well, much) light from the edges of the lens?

Yeah thought that would be a factor but it isn't

has anyone got any photos taken with the cokin circular polariser?
Im also looking for a polariser but worried about the cokins quality.

cheers

[spanna]

well ive been advised by a collage photography teacher to go with the lee filter system.
Does anyone use them or have experience of them?
