This Circular Polarizer Glass filter can be used to rule out and filter the scattering of light beam and make the light on the straight to your eyes, and then the view will be clear and natural. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The filter factor varies according to how the filter is rotated and its orientation to the sun.

great, will order more from linkdelight
With a cheap price and any photographer's "must have", I am very happy to have found Link Delight.
Buon filtro ad un ottimo prezzo, si deve capire che non ha una posizione fissa per lavorare al meglio, ma che va ruotato a seconda della situazione per ottenere il massimo del risultato.
Very good filter. I recommend this product.
Muy buena transacción de compra-venta. Salió todo segun lo pactado. Muy recomendable. Estoy conforme con tiempo y forma de envio; tanto asi con precio y calidad del producto adquirido.
Happy whith the purchase. Useful to avoid reflection and get some contrast!
Todo muy bien, funciona como indica la informacion
pros: very reasonable price, easy to use, works well for its price.
con: polarizing doesnt work very well.
you get wad you pay for.
Just like in "the old days" when shooting slide-film in high-altitude, a cpl-filter is an absoulute must.
This filter give me just the saturation I need, when shooting water and blue sky everyone needs a filter like this.
I really can't think of anything bad to say about this thing, it works like advertised. It really improves every shot I've taken outside, especially when sun is up but also improves saturation on cloudy days. Worth every penny and belongs to every photographers bag.
