Square filter help

[bluej511]

Alright well ive been looking at the Cokin P-system (hopefully its the right one) and realized that glass filters and holders are so much cheaper then buying a circular filter for every lens.

What filter holder do i get? Cokin or Lee?
Im thinking of getting some singh-ray glass since i only need to buy one and it will fit every lens i buy.

Whats the difference between 3x3 and 4x4 other then size?

Any help will be great

With your existing kit the Cokin P system should be fine. Note that these are resin, not glass.
If you were to buy an ultra wide lens such as the 10-22 EF-S then the larger filters such as XPro would be beneficial. The wider filters will help reduce the effect of vignetting.

Lee filters are higher quality and 100mm x 100mm (so would be better for wider lenses or full frame cameras), but they are very expensive and scratch easily (speaking from personal experience :evil: ).

A better option for the Cokin P-series holder is HiTech filters. They're a good bit better quality than the Cokin filters. The P-series can be used on ultra wide lenses, you would just need a wide angle holder so as not to vignette. IMHO, get the Cokin P series system.

whats the difference between cokin and hitech? i need something that POSSIBLY i could use singh ray filters in.

Now is singh ray gelatin to or is that pure glass?

HiTech quality falls between Lee and Cokin. Its better than Cokin and cheaper than Lee. In the UK, there can be supply problems. They do 2 main sizes 84mm and 100mm.
Sorry, but I don't know about the singh-ray filters.
