Can anyone offer any advice please on what filter type they are currently using please. I am using 2 lenses at the moment A Sony 18-250 and a Sigma 10-20 they have filter threads of 67mm and 77mm respectively which makes it pretty expensive to buy filters for both. I would like to use a polarizing filter and also a few neutral density filters and was thinking of the Cokin P series system which in theory should allow me to purchase 1 of each filter to slot into the universal holder leaving the holder fitting adaptor rings perm. on each lens.

Does anyone use this stuff? is it any good or is it best to only use screw on filters?

Thanks in advance.

No serious photographers here then ?

I use Hoya pro glass filters.

A circular polariser for specific effects such as to bring out the colours and blue skies and UV filters on each of my lenses. Yes they are expensive and 77mm.

But why put cheap filters on the end of expensive lenses :eek:

The Cokin slide in filters can be good, put I would really only recommend a grad ND filter to even out the contrast between skies and the ground. All of the others, whilst a bit of fun, are often overused. Anyway you can duplicate the effect in post processing.

Thats what I decided to do in the end.

77mm Kenko pro 1 circ polarizer with a 67mm -77mm step up ring and a Kood P series square holder with ND4 and graduated ND slot in filters.

Decided against skylight/UV/Protector filters for the moment due to slight flare issues.

There's often quite a debate for and against uv filters. The for brigade state that it offers protection for the end element, and the against brigade argue a loss of quality.

Yer pays yer money.....

I have never found any flare/contrast issues with the high quality filters. I use them as my kit is not stated as water/dust resistant by canon unless a filter is fitted. The only lens without a filter is my 300 f2.8. I wouldn't like to guess how much that would be if one was made that big!!!! :eek:

Have taken pictures with and without UV filter and can't tell the difference. Use it for protection and on my 50mm f1.8 use that or circ polarising.

After a month in Oz and a few months round scotland I was amazed how dirty the filters were. Quick and easy to clean, wouldn't have liked it to have been my lens I was cleaning.

I use Hoya UV and a 30 quid polarizer - May buy a more expensive one in due course as I like the results esp for blue sky, and cutting out reflections on water/glass etc

i use cokin p series filters and have found no probs with them,, i have only gone for a cicular pol. filter, and a medium dens. grad, i do not use UV filters for any of my lenses as with both of the others on there i dont see the point, and wouldnt benifit spending the extra money. Eventually i will be buying lee filters for my lenses, but as i am going to change them all soon, i am waiting to see what filter size i will need first, as they are MIGHTY expensive ! The cokin P series circular was about £70 and the grad was about £20 i think,, the Lee equiv. is at least twice the price, but worth the quality.

I bought a couple of filters for my 120-300 f/2.8 Sigma lens (110mm fitment IIRC). There aren't that many people that make filters, I don't think Hoya do.

In the end, I also got a few for my 18-70mm lens which is either 67 or 77mm can't remember.

Budget filters, but they seem to work fine. I haven't noticed an loss in PQ - the UV filters are proper glass and transparent to the eye. The polarising filter seems to do a wonderful job at obtaining the deep blue sky effect.

I guess more professional filters will give better results, but the way I looked at it, especially because I was a filter noob, was that it's not a lot of wasted money and gave me the chance to discover how it all works.

I got the stuff of treasuresale chap on ebay. Went there because they sold UV + CPL + other filter kits so you had everything for one lens size at decent prices
