100 mm filter holder system
I bought this holder system recently including the holder itself, 67mm and 77mm adapter rings, 10 and 6 stop nd filters, a 3 stop reverse grad filter and the polarizer filter.
Although one of the adapter rings and the polarizer filter were faulty, Urth customer support was quick to replace both.
The filters itself work impressively well, without any colour cast whatsoever.
The filter holder has a nice design and it works well but it would benefit from some minor changes like changing the colour from black to reflective white on the 2 attachment points and the knob in order to make it easier to check that the hole system is secure partucularly at dusk, night or dawn.
I am happy wit the product and would recommend it.
Last but not least trees are planted in result of us buying Urth products.
