Hi after reading some of the filters threads, I have narrowed my choice to the Hitech 100 series. I intend to get it from teamworkphoto for the price of 179Euro which is about SGD$300. The package consists of 3 NDs & 3 GNDs, a wide angle adapter ring, a 2-slot wide angle filter holder and 2 Lee filter wraps. I think the price is rather cheap compared getting locally here. Would like to hear from brothers and sisters who are using these filters for any comments and advise and whether is a good choice buy. I intend to use it for my Sigma 10-20 f4-5.6 77mm UWA.
