Filters

Are the Z sized filters more durable then the P sized? The price difference is quite big.

I spent a long time reading up about this, in the end I went for Cokin P series. They have a big range, are of good quality and are reasonably priced. What's more you can use other cheaper makes in them if you fancy a bargain. The only thing that I was concerned about was vignetting on wide lenses but you can hack the front off a normal holder like MattMatic said or Cokin actually manufacture a wide angle holder with one slot.

What size wide angle lens are we talking about when vignetting occures would i be ok with the 18-55 on my K10D. Has anyone got any experience with Kood or Hitech.

This is what cokin.co.uk says about the standard P holder

"For shorter focal lengths 20-24 or 28mm as well as for wide angle zooms (24-50mm / 28-85mm / 35-135mm) the Cokin P System is strongly recommended."

in the booklet that came with my holder it says this about the wide angle holder

"Can hold 1 filter (can be a polarizer) and allows the use of of filters with super wide-angle lenses (focal lengths under 20mm in 35mm format)."

it also says that even the X-PRO series (uses 118mm X 130mm filters) can only be used with lenses of 15mm onwards.

So all in, as clear as mud. At the prices of the P series and the fact they are compatible with Jessops, Kood and other non branded filters you can't go far wrong. You can always sell them on without much of a loss if vignetting becomes a problem.

My guess is that you are not going to see much vignetting using a P series on the 18-55.

Don't forget that the digital sensor is significantly smaller than a film frame (which is what Cokin are talking about when they mention focal lengths).

And the filter size is a mere 52mm.

A bit OT - but on Artizen web-site, one can buy it for 59 CAD. Does anyone know how they translate that into GBP - ie via the normal exchange rate, or like the common '1 to 1' we seem to see making it more like £59?

They charge $59 Canadian, it's your credit card company that fixes the exchange rate.

Thanks Mannesty.

I only asked, 'cos a PSP link I followed showed me the price in US dollars, and when I followed through the ordering process, and it discovered I am in the UK, the web-site changed the price to GBP - at the same figure - ie $59 =£59!!
