In neutral position the holder works very much like it did in the older version – it allow for easy rotation to position the filters as we want them. If you ever dropped your liter holder and saw your filter hit the ground and crush, you know that the neutral position has been both a blessing and very dangerous. And here is where LEE comes with possibly greatest change to the system: half-lock and full-lock positions.
In half-lock the blue locking ring holds the filter firmly to the adapter ring while still allowing for its rotation and proper filter adjustment. Thanks to the locking ring there is no threat of ever again losing the filter due to a sudden drop.
Half-lock position goes one step forward – and everybody who works with filters long enough will quickly recognize the importance of this position. It locks the filter holder in its place preventing any undesirable rotation, so the photographer can be sure that the position of the filters will not change during the course of taking images.
Also new filter guide blocks have undergone design change and now up to three filters can be used without vignetting, even on wide-angle lens. They are easily changeable and a lot more flexible than their predecessors.
