Vari-ND Filter (ND2 to ND400) test - Canon 550D/T2i and Sygma 30mm f/1.4

Bought 26 euros on Ebay, P&P included!<br />A very cheap "variable" neutral grey filter... which gives total control over the aperture when filming with a fast lens.<br />Not too bad for such an affordable item.<br />Judge by yourself.<br />NB: forgive the shaky camera, it was 10° C below zero! ;-)<br /><br />http://jeanbal.tv
