New Hitech Pro Stop ND Filter Review

When Lee released the ‘Big Stopper’ in 2010, they massively underestimated how much of a demand there would be for a decent 10 stop filter.  Before the Big Stopper arrived, the only square 10 stop ND filter was the 10 stop filter from Hitech.  Unfortunately this filter had a few problems.

    I purchased the big stopper and am returning it because it is not 100mm x100mm as advertised, but 99mm x 99mm. So it does not fit properly in my matte box holder.

    Tiffen and CA vision filters are actually 101 mm square, to ensure a good fit.

    The literature does not indicate it, but I would guess the lee filter is produced for a lee filter holder , unlike the pro standards of Tiffen and ca vision.

    At 199.00 (Canadian ) its also quite inferior to Tiffen. Very thin glass, flimsy pouch, and no protective cloth.

    I'll try the hi tech next.
